I worked on a Blast Furnace starting in the early 1970s and at that time they would skim the slag off the iron and into the pots. And if you filled all the pots you would divert into a pit. The pots would then be dumped into a much larger pit away from the furnace. They would be molten and it would light up the sky for a minute or two. When the pots would come back and be spotted for another cast, liquid lime would be sprayed on the inside wall to make any skull build up slide off easier during the next dump. One other interesting thing would happen if you were making hot 2800F iron and it was limey basic slag, with a higher B/A ratio. You would under fill the pot at least 6" from the top, because once the top surface had a thin crust from cooling it would swell up from gases and start spilling on the ground. Our technique was to throw a wood board on top or moist clay balls. Either would have a boiling effect and allow the gas to escape.
you sure know what you're talking about. I worked at us steel a long time ago. Gary works. they used to spray the inside of the cinder ladles with lime to keep the slag from sticking to the cinder ladle. sometime they would flush the slag into a pit full of water. as the molten slag would be coming out of the furnace it was mixed with water and the result would be like popcorn. they would use that stuff for paving material.
@@danielthoman7324 On another furnace I worked on they used to make popcorn slag by injecting water thru the slag as it falling into the slag pit. Made quite the racket! Especially when iron was accidentally running down the slag runner because of furnace condition or bad practices/maintenance. I worked in Cleveland.

I've seen being poured out and the shell comes out after into a big pit, seems a better, faster way. How long would the league have to sit in a pot for it to solidify like this and why would they do it like this?
Buddy of mine gave me a tour for 3 hours where he worked. It was an EAF plant, we started at the ladles where guys were re-bricking them with fire brick, other being pre-heated. The sound of the gas blowers heating these ladles on their side were deafening. We were suited up with double hearing protection, until you've seen it, you can't understand how loud it was. Those who know what I mean will get it. All through the furnace then the casting and the rolling mills. I never saw anything like this though. Watching the lid on the furnace open, as bright as the sun they said, behind 3" think dark, almost black green glass. WOW man, like looking into a volcano erupting. Charging the furnace with overhead crane, dumping rail car size loads was one of the most incredible operations of manmade machinery in my life. And then, the arc furnace melting the charge - holy shit, the size of everything. Telephone poles made of carbon dancing through the lid. Mind blowing. And then some dude in a fire suit lancing the furnace that allowed the molten steel to pour like tea into the ladle.... man, a thousand ways to die in that place. It's just the size of everything that's beyond amazing to see. At the end I told him "Who ever imagined this, designed it, they are a madman. LOL! Man, what a cool adventure that was.
Light, heat, sound, scale, a place of every extreme by your description! Just like everything else in our world, a seemingly impossible task made downright ordinary by scope of human endeavour.
@@ricbchirop4355 I hope you get the chance also, it will be a life changing experience I'm sure. It certainly left an impression on me I'll never forget. I didn't even talk about the caster and the journey through the rolling mills to the coiler, which completes the process. after the metal is turned into liquid in the furnace, the guy lances the EAF and the metal pours into a ladle underneath it - 2 stories down - the ladle goes through the metallurgist department where they check the makeup and add other elements to make the pour of steel to the desired order. It then drops into the caster - This is where a glowing red brick starts becoming a block of steel, 20 tons at a time. Then it starts on a journey through the rolling mills where it starts as a block that runs through a series of rollers, smashing it thinner and wider as it goes. Then it goes through another oven, 150 foot long if I'm recalling correctly - then it hits the finishing mill series of rollers, 5 or 6 of them. the sheet steel is spit out and is doing about 40 or 50 miles an hour out the other end and hits what is called the "coiler" that starts to roll it up as the big rolls you see on trucks, 20 tons each. Every time the end of the steel hits a rolling mill section it feels like an earthquake because of how it's smashing it's thickness. The engineering that goes in to how the rolls are machined/tapered - just incredible. Consider, the steel, while it's hot/soft, is spread out from the center to the edges in descending order so that the very last roller it comes out to a precise thickness across it's width. the geometry and precision of this otherwise brutal operation is as precise as making surgical instruments. And to top it all off, which to me was amazing - every coil that comes off the production line, is already sold to a customer. There's no such thing as making "stock" material for inventory.
You should consider writing. Your words had me standing right there alongside you. If you haven't taken writing classes you have a natural gift, well, even if you have, too.
Some internet searching: Slag is stony waste matter separated from metals during the smelting or refining of ore. Not sure what a skull is, but based on the video, I would assume the "skull" is the stuff in the solid chunk dropped out of the slag pot. A slag pot is a metal ladle for collecting molten slag flowing from the tap hole of a steel-smelting furnace during smelting. It is positioned under the furnace on a car that moves along a special trestle for slag removal. Emptying slag pots is time-consuming and often difficult. Using chisel operated hammers and banging slag pots against hard objects to remove the slag can additionally damage the pot and may be dangerous for staff deployed on site. Fractum breakers have been designed to efficiently and effectively de-skull slag pots without causing damage. This is achieved by adjusting the breaker’s impact power, enabling the adaptation of energy levels, depending on the task. The steel milling breakers have been designed to remove solidified skull from slag pots, which has a higher success rate compared to traditional de-skulling techniques like oxy-cutting. Clients have hailed the breaking technology for its ability to cope with slag pots handled by both ladles and overhead cranes.
The other part of this I left out was the whole point of these skulls. Now, I don't know for sure, but it seems like there are two ways to dump slag into a slag pit (to get rid of it or store it, I'm not sure). The first way is to move the slag pot on the car (train rails) to the slag pit before the slag cools and hardens and is still molten. Then you dump the slag like river of lava into the slag pit. But apparently this takes up a lot of room and I would guess later recovery of the slag for industrial purposes would be more difficult. So instead, you can let the slag cool into these hard boulders with a creamy molten centers called skulls. Then you can dump out the skulls into the pit and it takes up a lot less room. There is a video on here of a skull exploding, I assume from a build up of pressure. So that's one reason why they probably break them up. Another is to just speed up the cooling process of the skull so it's not a dangerous ball of lava waiting to leak onto something important.
Stupid question is stupid, but as basic slag is a mix of both mineral and metal oxides, would (instead of pouring it into pits, or de-skulling, letting it cool, then grinding it up, and adding it to concrete powder) it possible for molten basic slag to be poured into molds, and cooled until fully hardened ala pre-fab concrete ... in other words, would solid basic slag have the same properties of some pre-fab concrete, or would it just crumble under compression ..?
I don't know, but from watching other videos, it looks like slag deposits once hardened have to be jackhammered out of the molds. So I'm guessing that they need to get the stuff out of molds pretty quickly. But hopefully an expert can weigh in.
In '68, I worked in a blast furnace. The hot iron flow down a channel to a large container called a "pig". The pig was part of a Railroad car. The Slag went into a large bowl also mounted on a Railroad car. The slag was dangerous. We had to coat the bowl with lime. The bowl had to be completely dry. If a water pocket was formed in the slag bowl, then the slag would blow up. Hot slag was dangerous to be around. If slag got on your clothes, then it would burn straight threw to you skin, and burn a hole in your skin. Iron was not a problem. Iron didn't explode, and if hot iron landed on your clothes it brushed off.
I too worked at a Pig Machine before I moved up to the Blast Furnace. I was a Sticker Man. If one of the pigs stuck in the mold (usually because the mold had a crack which allowed the iron a place to "grab" on to) I was the guy a took a bar and hit it while it was stuck upside down. You did work with a heavy cage gauge steel cage over you but.. if one didn't release and fall to the ground after striking it, you would leave the cage and keep smacking it until it dropped. You had to be strong, agile and dumb to be good at it. I was all of the above.... And then you had to move the pigs to a pile manually away from the line.

THIS reminds me of the Steel Mills where I grew up! A Locomotive Engineer, my father often pulled strings of "Crucible Cars" from the blast furnaces to one of several casting plants nearby, to be turned into Tools, Engine Blocks and numerous other items that kept our world turning from the 1950s until 1985, when he retired! Unusual looking, these Very Heavy and Extremely HOT Rail Cars, rolled through the middle of several residential neighborhoods! It was the one job that my father disliked! He was always "Very Afraid" of one (or more) of the cars to derail and overturn, or to simply Split Open and spill it's load of Tons & Tons of Liquid Fire! One tiny drop of 2000 to 3000 degree (or more) of molten metal, will ignite nearly anything it touches and "that" always worried my father, terribly! Most of those homes were in economically depressed neighborhoods and "that fact", made my father worry even more!
@Slick Armor Yeah, that's basically it, because poor people already don't have much, and they would generally have a harder time recovering from something like that than people with more money.
Yeah them little “drops” specks/sparks. Tossing in things or getting samples or temp poles into the ladle. They would come back an make burns. Tiniest of sparks would hit our uniform go through it or hit you in the neck and just roll down your body in your clothes from moving around to keep from burning. The worst when whatever it hits if you didn’t move quick enough it would stick an keep burning. Vs the moving around to keep it moving not to to bad that it cooled enough that it wasn’t a issue an keep working. If it hit the boots an some way slipped through the tongue of the boot them definitely burned. Can’t shake your foot around in them to not be. It just sits in that spot. Fun times Kinda like being attacked by yellow jackets lol. If someone was jumping or shaking or whatever ha ya knew they were getting stung up ha.
Wow,the memories came flooding backs after watching this and reading the comments of others. I used to do that in a steel mill in Oregon...but I was given a Caterpillar 977 track dozer with a bucket to do that. This being the Pacific North-wet... one of those skulls broke open on a small puddle of water!! Boom boom boom,out went the lights! 😄😆 But I lived and was ok!
Back in the late 1960s are used to go up to Middletown Ohio to old Armco steal and watch them do this of course I was outside the fence that was very interesting
In the 70's I worked in the steel mill in the railroad car repair dept. I worked on the torpedo shaped iron cars and the cinder ladle cars. After the ladle cars were filled at the blast furnaces, they were taken across the river to a special dump. Occasionally part of the skull would get stuck in the bottom of a ladle. That car would be set aside to cool. After that coing time the car would be brought into our building. I had to climb up to the overhead crane that was who knows how high off the ground. My helper would connect two cables to the top of the ladle and I would lift it out of the cradle and lay the ladle on the ground. My helper would disconnect the two cables and connect one heavy cable to the bottom of the ladle. I would carefully lift it off the ground and move it to the far end of the building where we had an ingot that was partially buried in the ground. I would lift the lift the ladle even with the ingot and get it swinging like a bell, then moving the craneso the ladle smacked the ingot. One or two smacks and the piece of skull would fall out. Immediately I had to move the crane back to avoid being gassed. Put the ladke on the ground and the helper hooked up the two cables, reinstalled the ladle in the frame of the car. Then the car was put back in service. Hard to believe we did crazy stuff like that.
This reminds me of my Uncle who was actually a Fractum Model 100. He used to take me to work and deskull hot metal all day until he was sold for scrap metal in 1994.
+Thad ward Yeah, and it was pretty cool, actually! Have you ever seen a massive ball of red hot metal waste being broken by a machine sledge hammer before?
When I was a teenager working the Homestead mills in the 50s, we didn't have impact hammers, broke the slag by hand with a 5 lb hammer and cold chisels. "If you get burned, you get burned" the foreman told us.

@@jerrykinnin7941 Ah, so the slag isn't just waste it has some value still? Thank you for your answer, I appreciate it. And honestly, we basically made robot giants to help us do very specific stuff. Or rather, found ways to make ourselves robot giants. It is incredibly cool.
I hail from an old steel & coal town, used to be iron, limestone & coal area. Here they started small in the 1700s and by my time, the slag heaps had become mountains. The slag and coal wastes, were simply hauled up to the tops of the ‘tips’ mountains and added to the top-sides of said mountains. Some would slide down and some would stick fast. It takes a born ‘n’ bred local, to be able to look at a mountain and tell if it’s a natural mountain or a manmade mountain or a bit of both. Slag was often poured into earthen pits and left to cool into blocks. These blocks are typically 4-5ft. long x 1ft. high x 1-2ft. wide. They were used to build walls, where the strength of stone was needed but the looks of brick was not required. There are still walls made of these blocks, they made good retaining walls. Typically held by rough ash mortar; as suggested, they were used where a strong structure was needed at a very low price. Though I takes a crane to move them.
@@weatheranddarkness - Those that I know of, have become parts off privately funded home builds. They’re mostly grown over with ivy/creepers or have been rendered over. When I was in my early teens, me and my friends were on our way to some waste ground. This entailed climbing down or jumping off one such wall. The wall must have been well over 100yrs. old at the time. The rough ash+lime mortar was crumbling. One moment I standing on the wall and the next, the top of the wall slid, sending me into the brambles below. The brambles broke my fall, which was good if a little prickly. Much to my friends’ amusement. However, before I could extract myself, the rest of the wall collapsed along apx. 12ft., (3.7m) burying me in the process. Broke off the end of my left fibula and luckily, a block rolled over my head while being partly supported by moving rubble. That one just broke my nose… could have been worse. My friends dug me out with the bare hands; and a couple of lads on their way to play tennis, bundled me into their 1960s Mini and took me home. Another trip to the hospital for me from there. Most of that wall still exists but has been rendered over or buried by garden make-overs, (the houses weren’t there in my teens).
I had a 1985 Dodge Power Ram D50 4x4 pickup truck that I entered into every ugly pickup truck contest I could find. I named it, "Slag." In two years of ownership, I made just under $10,000 in just prize winnings from Slag. One day, Slag was stolen from a parking lot at work. Four months later, Slag was found in parts because it was parked overhanging a railroad so the train would hit it. I still miss Slag, the best $100 pickup truck anybody could ever have. I still have Slag's shiftstick and hood ornoment with a picture.

@@venomsoul1147 For the last 26 years, I have been in the company of the RMS Stargazer. The Stargazer and I started our journey together in 1996. She started her life with me as a 1997 jeep Wrangler Sport, convertible. If ever anything could be a friend, it has been Stargazer. I have been through two careers, 10 friends, three homes, and various economical levels in life. I lost my home this January of 2022 in a fire. The Stargazer and I spent three nights together because I had nowhere to stay. All that was saved from the fire was what was Stargazer and me. It was a chest of tools, a length of nylon rope, a shovel, duct tape, plastic bags, crow bars, and my five work uniforms. Work dismissed me until I got my house in order because I was placed in a hotel very far away. During my hotel residency, Stargazer stopped running for the first time in our life together. For awhile, I thought of calling a tow truck and ending our journey together. But with nothing else to do at the hotel, I took off the wiring harness, (no easy task) and started repairing it. It took over a month to remake the wiring harness. It was a labour of love. Early July, I reinstalled the rebuilt wiring harness and Stargazer came back to life. She ran terrible due to the damaging voltages that surged through her when she went into a coma. But I lovingly kept repairing her. Today, she runs like new again. She has been with me through so much. No human, "friend," could ever be so wonderful and loyal. I love you Stargazer. I love you forever.

It's simple. A dualized parping couplet is rutted into a fissure known as a Sultan's Hat, thereby releasing super-ingot into a non-restrained region that you see in the video.
The mill i haul to has these wishbone shapped haulers that take the slagpots into a building for "de-sculling" its cool to watch them at night. All glowing and steaming in the rain. Slag is used as an ingredient in concrete.
If it is blast furnace iron slag then you're in the money! Allow it to cool, pulverize it, crush it, grind it, and mill it until it is as fine a baby powder or bleached white wheat flour powder. Mix an equal proportion of slaked lime powder with an equal proportion of blast furnace iron slag powder and an equal proportion of clay powder. Mix and then add water after it has totally blended together while continuing mixing it. And add some sand and gravel. And you got a modernized version of Smeaton concrete. The original Smeaton cement foundation in England facing the continous pounding of the Atlantic ocean is still intact and as food as new after almost 120 years of service as a lighthouse. The lighthouse has to be dismantled and place further inland because the natural rock formation is being worn away by the Atlantic waves but the Smeaton cement foundation is still as good as new and virtually unaffected by the corrosive seawater itself. But no one has ever tried using steel slag as part of the cement mortar and concrete mixture. www.centuryhouse.org/Next/wp-content/uploads/2015/01/2006summ.pdf
Just going to take an uneducated guess here: I'm guessing the slag pot is the train car - it's used to carry the unwanted (non-metallic) leftovers from the smelting process. The Fractum Model 100 is a tool for breaking up the chunks, as it would be easier to move small chunks of slag (e.g.: use a regular front-end loader). Deskulling is the process of emptying a slag pot where things have already cooled to the point of where they aren't easily removed from the slag pot. That's just a guess, though.
When you smelt iron ore the melt separates into two parts: iron and lava rock. The molten iron sinks to the bottom of the melt and the molten lava floats on top. The lava is a waste product and is either skimmed or drained off the top of the melt and is removed for disposal as slag.
@@Spectans1 a drop ball is like a wrecking ball only it's usually attached to a crane overhead. deskulling is knocking out the slag that sticks to the inside of the cinder ladle. I worked in a steel mill a long time ago. back when America still had a lot of steel mills.
At my previous job they had this underground pits where the crane dumps orange hot semi hardened slag in. Then they lower the lid like a toilet seat, and spray water from the lid and suck out the steam through the chimney through an underground tunnel. The temperature shock turns slag into loose rubble and sand, then they use an excavator to manually scoop them out into a truck. Then it gets sent to a yard where they run it through a conveyor that separates still usable iron out and filters the rest by size. Much of it done without external contractors. Really precarious builds, but they work lol. Obviously nobody calculated anything so from there we do continuous adjustments and improvement such as hand rails, making walkways stronger, adjusting the angle of the mesh, etc. But theres this crazy situation on the vibrator feeder below a hopper. This one hook on the trough keeps breaking at the exact same spot and people just kept welding on bent pieces of rebar, which then breaks again, just like the original hook. At least 4 broken off bits of the same design welded one atop another, yet nobody thought maybe they should do an upside down U shape or just try something else so it doesnt keep breaking. Anyways idk what they do with the slag but the dust and skull with iron in them gets fed back into the furnaces.
Nice! I have been working as a blaster💥on power plants wich use household trash as fuel. We blasted slag off the tubes, while the plant was running(online blasting) Doing safety blasting in the fire room before workers could enter and clean the rest of the slag off. NO ONE have permission before the safety blasting was done💥 Very dangerous job!
It would only take a couple days. The outer crust acts as a heat sink instead of an insulator. So it is actively drawing out the heat. You can see how thick the crust was already and that is just after a few hours.
It's an interesting though. Consider that earth is somewhat similar to this slag lump, except about 4 million times larger in diameter (assuming 3m diameter slag) but earth is still glowing hot inside after more than 4 billion years.
You could watch engineers empty slag in to a ravine when Bethlehem Steel was in operation. That was a sight to see, my old man is a rail fan, he use to take me trainspotting all the time as a child and watching slag being dumped was one of those things.

Slag is the impurities from the steelmaking process. This pot was where they transported the slag in. Now they dumped it out, along with the refractory lining of the pot, and are breaking it up so it cools. Slag can be recycled into road materials or other usual when it is cooled and ground up.

Steve Waclo Slag, a waste product of ore refinement and steel production is collected in slag pots. Cooled slag is often metallic glass in appearance and is fairly dense. After it's tipped from the slag pot, it must be broken into manageable pieces and allowed to cool. The mechanism resting against the slag mass is a guide for a steel rod used to split the slag so that it can disposed of, probably, by a front loader.
+Thanks Justin! That 411 was probably also buried somewhere in the 400+ comments! but I'm lazy. Although, I have discovered that scanning comments quickly, picking out anything exceeding one line, is often a worthwhile exercise. There should be a way to move highly liked comments to the top!
I always wondered what happens to the slag when cleaned out of these slag pits. The slag left over is basically obsidian and various metallic oxides, that are hard and abrasive material . So I always wondered if this material would be crushed down to make abrasives or something rather than just being dumped somewhere, or if it could be turned into some sort of insulation or rockwool. My local municipality does not allow glass and certain materials in our landfills for this purpose because it does not break down and this steel slag would be basically the same thing. So hopefully it was repurposed in some way. But then again this is Big industry and companies making millions of dollars don't care about these kind of things and find ways around it kind of like Safelite Auto glass. They claim to recycle all of the glass windshields that come into their place and classify themselves as a green operation because of this. Funny thing is you can go to almost any Safelite Auto Glass store and find the dumpster out back that goes to your landfill; full of broken windshields. I actually have photographic evidence of this from when I had my windshield replaced and went to throw something in the dumpster while I was waiting. When I asked the manager about this, his excuse was that they can only recycle OEM glass because aftermarket glass cannot be made into a new windshield. That was the first lie because that window was the original window for my vehicle and it was OEM, and later that night when I went back to the shop I was able to verify that my windshield was in that dumpster I was able to verify this because of the inspection sticker cut out that matched perfectly. My argument was that glass is indefinitely recyclable and so his answer makes no sense and even if it couldn't be made into a new windshield; that it could be made into things like concrete aggregate, fiberglass insulation material, and abrasives, and many other things which Safelite claims to do being partnered with Shark industries and Owens Corning fiberglass. Then I informed him of my local municipality having ordinances behind glass waste in residential trash and that that dumpster was in violation and a simple phone call could get them a hefty fine. They will never admit it; but I got an email later that night after my online complaint from someone higher up actually offering me all kinds of promos, discounts, and even refund for my service they would just need me to esign some paperwork. Basically they were offering me hush money to keep my mouth shut and the e-signature would probably have been put on a non-disclosure. I didn't take it and put a Google review with the photos of the windshields in a residential dumpster along with the location of the branch that was doing it up on the internet. The next week when I drove by the place I found that they had a new garbage company; as waste management, the company they were working with, dumped them 🤣🤣. I'm sure they're still doing it though so I was only able to make a difference for a couple of months 🤷 but hey it was worth it.

I worked on a Blast Furnace starting in the early 1970s and at that time they would skim the slag off the iron and into the pots. And if you filled all the pots you would divert into a pit. The pots would then be dumped into a much larger pit away from the furnace. They would be molten and it would light up the sky for a minute or two. When the pots would come back and be spotted for another cast, liquid lime would be sprayed on the inside wall to make any skull build up slide off easier during the next dump. One other interesting thing would happen if you were making hot 2800F iron and it was limey basic slag, with a higher B/A ratio. You would under fill the pot at least 6" from the top, because once the top surface had a thin crust from cooling it would swell up from gases and start spilling on the ground. Our technique was to throw a wood board on top or moist clay balls. Either would have a boiling effect and allow the gas to escape.
you sure know what you're talking about. I worked at us steel a long time ago.

@@TheDrewcas I'm only speaking the truth about those bite sized volcanos.
the pies cooked in the deep fat fryer were the best
Buddy of mine gave me a tour for 3 hours where he worked. It was an EAF plant, we started at the ladles where guys were re-bricking them with fire brick, other being pre-heated. The sound of the gas blowers heating these ladles on their side were deafening. We were suited up with double hearing protection, until you've seen it, you can't understand how loud it was. Those who know what I mean will get it. All through the furnace then the casting and the rolling mills. I never saw anything like this though.
Watching the lid on the furnace open, as bright as the sun they said, behind 3" think dark, almost black green glass. WOW man, like looking into a volcano erupting. Charging the furnace with overhead crane, dumping rail car size loads was one of the most incredible operations of manmade machinery in my life. And then, the arc furnace melting the charge - holy shit, the size of everything. Telephone poles made of carbon dancing through the lid. Mind blowing. And then some dude in a fire suit lancing the furnace that allowed the molten steel to pour like tea into the ladle.... man, a thousand ways to die in that place.
It's just the size of everything that's beyond amazing to see. At the end I told him "Who ever imagined this, designed it, they are a madman. LOL! Man, what a cool adventure that was.
You've got a way with words Leonardo... thanks fir sharing that dude. 👍🏽🇺🇸
Light, heat, sound, scale, a place of every extreme by your description! Just like everything else in our world, a seemingly impossible task made downright ordinary by scope of human endeavour.
Im so jealous Leo , love😅 to go on a visit around an EAF. If ever I do I will have Fire ,by Aurthr Brown playing on headphones
@@ricbchirop4355 I hope you get the chance also, it will be a life changing experience I'm sure. It certainly left an impression on me I'll never forget.
I didn't even talk about the caster and the journey through the rolling mills to the coiler, which completes the process.
after the metal is turned into liquid in the furnace, the guy lances the EAF and the metal pours into a ladle underneath it - 2 stories down - the ladle goes through the metallurgist department where they check the makeup and add other elements to make the pour of steel to the desired order. It then drops into the caster - This is where a glowing red brick starts becoming a block of steel, 20 tons at a time. Then it starts on a journey through the rolling mills where it starts as a block that runs through a series of rollers, smashing it thinner and wider as it goes. Then it goes through another oven, 150 foot long if I'm recalling correctly - then it hits the finishing mill series of rollers, 5 or 6 of them. the sheet steel is spit out and is doing about 40 or 50 miles an hour out the other end and hits what is called the "coiler" that starts to roll it up as the big rolls you see on trucks, 20 tons each. Every time the end of the steel hits a rolling mill section it feels like an earthquake because of how it's smashing it's thickness. The engineering that goes in to how the rolls are machined/tapered - just incredible. Consider, the steel, while it's hot/soft, is spread out from the center to the edges in descending order so that the very last roller it comes out to a precise thickness across it's width. the geometry and precision of this otherwise brutal operation is as precise as making surgical instruments.
And to top it all off, which to me was amazing - every coil that comes off the production line, is already sold to a customer. There's no such thing as making "stock" material for inventory.
You should consider writing. Your words had me standing right there alongside you. If you haven't taken writing classes you have a natural gift, well, even if you have, too.
Some internet searching:
Slag is stony waste matter separated from metals during the smelting or refining of ore. Not sure what a skull is, but based on the video, I would assume the "skull" is the stuff in the solid chunk dropped out of the slag pot.
A slag pot is a metal ladle for collecting molten slag flowing from the tap hole of a steel-smelting furnace during smelting. It is positioned under the furnace on a car that moves along a special trestle for slag removal.
Emptying slag pots is time-consuming and often difficult. Using chisel operated hammers and banging slag pots against hard objects to remove the slag can additionally damage the pot and may be dangerous for staff deployed on site.
Fractum breakers have been designed to efficiently and effectively de-skull slag pots without causing damage. This is achieved by adjusting the breaker’s impact power, enabling the adaptation of energy levels, depending on the task.
The steel milling breakers have been designed to remove solidified skull from slag pots, which has a higher success rate compared to traditional de-skulling techniques like oxy-cutting. Clients have hailed the breaking technology for its ability to cope with slag pots handled by both ladles and overhead cranes.
Feint that's some intense googling. thx bro
Feint thank u boss, i was about to embark on a quest to figure out why this is so awesome lol
The other part of this I left out was the whole point of these skulls. Now, I don't know for sure, but it seems like there are two ways to dump slag into a slag pit (to get rid of it or store it, I'm not sure). The first way is to move the slag pot on the car (train rails) to the slag pit before the slag cools and hardens and is still molten. Then you dump the slag like river of lava into the slag pit. But apparently this takes up a lot of room and I would guess later recovery of the slag for industrial purposes would be more difficult. So instead, you can let the slag cool into these hard boulders with a creamy molten centers called skulls. Then you can dump out the skulls into the pit and it takes up a lot less room. There is a video on here of a skull exploding, I assume from a build up of pressure. So that's one reason why they probably break them up. Another is to just speed up the cooling process of the skull so it's not a dangerous ball of lava waiting to leak onto something important.
Stupid question is stupid, but as basic slag is a mix of both mineral and metal oxides, would (instead of pouring it into pits, or de-skulling, letting it cool, then grinding it up, and adding it to concrete powder) it possible for molten basic slag to be poured into molds, and cooled until fully hardened ala pre-fab concrete ... in other words, would solid basic slag have the same properties of some pre-fab concrete, or would it just crumble under compression ..?
I don't know, but from watching other videos, it looks like slag deposits once hardened have to be jackhammered out of the molds. So I'm guessing that they need to get the stuff out of molds pretty quickly. But hopefully an expert can weigh in.

In '68, I worked in a blast furnace. The hot iron flow down a channel to a large container called a "pig". The pig was part of a Railroad car.
The Slag went into a large bowl also mounted on a Railroad car.
The slag was dangerous.
We had to coat the bowl with lime. The bowl had to be completely dry. If a water pocket was formed in the slag bowl, then the slag would blow up.
Hot slag was dangerous to be around. If slag got on your clothes, then it would burn straight threw to you skin, and burn a hole in your skin.
Iron was not a problem. Iron didn't explode, and if hot iron landed on your clothes it brushed off.
I too worked at a Pig Machine before I moved up to the Blast Furnace. I was a Sticker Man. If one of the pigs stuck in the mold (usually because the mold had a crack which allowed the iron a place to "grab" on to) I was the guy a took a bar and hit it while it was stuck upside down. You did work with a heavy cage gauge steel cage over you but.. if one didn't release and fall to the ground after striking it, you would leave the cage and keep smacking it until it dropped. You had to be strong, agile and dumb to be good at it. I was all of the above.... And then you had to move the pigs to a pile manually away from the line.

THIS reminds me of the Steel Mills where I grew up! A Locomotive Engineer, my father often pulled strings of "Crucible Cars" from the blast furnaces to one of several casting plants nearby, to be turned into Tools, Engine Blocks and numerous other items that kept our world turning from the 1950s until 1985, when he retired!
Unusual looking, these Very Heavy and Extremely HOT Rail Cars, rolled through the middle of several residential neighborhoods! It was the one job that my father disliked! He was always "Very Afraid" of one (or more) of the cars to derail and overturn, or to simply Split Open and spill it's load of Tons & Tons of Liquid Fire! One tiny drop of 2000 to 3000 degree (or more) of molten metal, will ignite nearly anything it touches and "that" always worried my father, terribly! Most of those homes were in economically depressed neighborhoods and "that fact", made my father worry even more!
@Slick Armor Because some people have empathy.
@Slick Armor Yeah, that's basically it, because poor people already don't have much, and they would generally have a harder time recovering from something like that than people with more money.
Yeah them little “drops” specks/sparks. Tossing in things or getting samples or temp poles into the ladle. They would come back an make burns. Tiniest of sparks would hit our uniform go through it or hit you in the neck and just roll down your body in your clothes from moving around to keep from burning. The worst when whatever it hits if you didn’t move quick enough it would stick an keep burning. Vs the moving around to keep it moving not to to bad that it cooled enough that it wasn’t a issue an keep working.
If it hit the boots an some way slipped through the tongue of the boot them definitely burned. Can’t shake your foot around in them to not be. It just sits in that spot.

Back in the late 1960s are used to go up to Middletown Ohio to old Armco steal and watch them do this of course I was outside the fence that was very interesting
In the 70's I worked in the steel mill in the railroad car repair dept. I worked on the torpedo shaped iron cars and the cinder ladle cars. After the ladle cars were filled at the blast furnaces, they were taken across the river to a special dump. Occasionally part of the skull would get stuck in the bottom of a ladle. That car would be set aside to cool. After that coing time the car would be brought into our building. I had to climb up to the overhead crane that was who knows how high off the ground. My helper would connect two cables to the top of the ladle and I would lift it out of the cradle and lay the ladle on the ground. My helper would disconnect the two cables and connect one heavy cable to the bottom of the ladle. I would carefully lift it off the ground and move it to the far end of the building where we had an ingot that was partially buried in the ground. I would lift the lift the ladle even with the ingot and get it swinging like a bell, then moving the craneso the ladle smacked the ingot. One or two smacks and the piece of skull would fall out. Immediately I had to move the crane back to avoid being gassed. Put the ladke on the ground and the helper hooked up the two cables, reinstalled the ladle in the frame of the car. Then the car was put back in service. Hard to believe we did crazy stuff like that.
Did the helper use some rod tool to handle the cables?
This reminds me of my Uncle who was actually a Fractum Model 100. He used to take me to work and deskull hot metal all day until he was sold for scrap metal in 1994.

Thank you for your answer, I appreciate it.
And honestly, we basically made robot giants to help us do very specific stuff. Or rather, found ways to make ourselves robot giants. It is incredibly cool.
I hail from an old steel & coal town, used to be iron, limestone & coal area. Here they started small in the 1700s and by my time, the slag heaps had become mountains. The slag and coal wastes, were simply hauled up to the tops of the ‘tips’ mountains and added to the top-sides of said mountains. Some would slide down and some would stick fast. It takes a born ‘n’ bred local, to be able to look at a mountain and tell if it’s a natural mountain or a manmade mountain or a bit of both.
Slag was often poured into earthen pits and left to cool into blocks. These blocks are typically 4-5ft. long x 1ft. high x 1-2ft. wide. They were used to build walls, where the strength of stone was needed but the looks of brick was not required. There are still walls made of these blocks, they made good retaining walls. Typically held by rough ash mortar; as suggested, they were used where a strong structure was needed at a very low price. Though I takes a crane to move them.
I'd love to see some of those walls! Can you point me anywhere?
@@weatheranddarkness - Those that I know of, have become parts off privately funded home builds. They’re mostly grown over with ivy/creepers or have been rendered over.
When I was in my early teens, me and my friends were on our way to some waste ground. This entailed climbing down or jumping off one such wall. The wall must have been well over 100yrs. old at the time. The rough ash+lime mortar was crumbling. One moment I standing on the wall and the next, the top of the wall slid, sending me into the brambles below. The brambles broke my fall, which was good if a little prickly. Much to my friends’ amusement.
However, before I could extract myself, the rest of the wall collapsed along apx. 12ft., (3.7m) burying me in the process. Broke off the end of my left fibula and luckily, a block rolled over my head while being partly supported by moving rubble. That one just broke my nose… could have been worse. My friends dug me out with the bare hands; and a couple of lads on their way to play tennis, bundled me into their 1960s Mini and took me home. Another trip to the hospital for me from there. Most of that wall still exists but has been rendered over or buried by garden make-overs, (the houses weren’t there in my teens).
I have no idea what I just watched... but I loved it.
So nice to see how the glowie stuff is beeing freed 😄
Surprisingly, very entertaining. "Deskulling" is such a descriptive word to describe it.
All that terminology is a deliberate choice
I had a 1985 Dodge Power Ram D50 4x4 pickup truck that I entered into every ugly pickup truck contest I could find. I named it, "Slag." In two years of ownership, I made just under $10,000 in just prize winnings from Slag. One day, Slag was stolen from a parking lot at work. Four months later, Slag was found in parts because it was parked overhanging a railroad so the train would hit it. I still miss Slag, the best $100 pickup truck anybody could ever have. I still have Slag's shiftstick and hood ornoment with a picture.

@@venomsoul1147 For the last 26 years, I have been in the company of the RMS Stargazer. The Stargazer and I started our journey together in 1996. She started her life with me as a 1997 jeep Wrangler Sport, convertible. If ever anything could be a friend, it has been Stargazer. I have been through two careers, 10 friends, three homes, and various economical levels in life. I lost my home this January of 2022 in a fire. The Stargazer and I spent three nights together because I had nowhere to stay. All that was saved from the fire was what was Stargazer and me. It was a chest of tools, a length of nylon rope, a shovel, duct tape, plastic bags, crow bars, and my five work uniforms. Work dismissed me until I got my house in order because I was placed in a hotel very far away. During my hotel residency, Stargazer stopped running for the first time in our life together. For awhile, I thought of calling a tow truck and ending our journey together. But with nothing else to do at the hotel, I took off the wiring harness, (no easy task) and started repairing it. It took over a month to remake the wiring harness. It was a labour of love. Early July, I reinstalled the rebuilt wiring harness and Stargazer came back to life. She ran terrible due to the damaging voltages that surged through her when she went into a coma. But I lovingly kept repairing her. Today, she runs like new again. She has been with me through so much. No human, "friend," could ever be so wonderful and loyal. I love you Stargazer. I love you forever.

No, the exact opposite, in fact.
not really though, its still red in the middle
If it is blast furnace iron slag then you're in the money! Allow it to cool, pulverize it, crush it, grind it, and mill it until it is as fine a baby powder or bleached white wheat flour powder. Mix an equal proportion of slaked lime powder with an equal proportion of blast furnace iron slag powder and an equal proportion of clay powder. Mix and then add water after it has totally blended together while continuing mixing it. And add some sand and gravel. And you got a modernized version of Smeaton concrete. The original Smeaton cement foundation in England facing the continous pounding of the Atlantic ocean is still intact and as food as new after almost 120 years of service as a lighthouse. The lighthouse has to be dismantled and place further inland because the natural rock formation is being worn away by the Atlantic waves but the Smeaton cement foundation is still as good as new and virtually unaffected by the corrosive seawater itself. But no one has ever tried using steel slag as part of the cement mortar and concrete mixture. www.centuryhouse.org/Next/wp-content/uploads/2015/01/2006summ.pdf

Just going to take an uneducated guess here:
I'm guessing the slag pot is the train car - it's used to carry the unwanted (non-metallic) leftovers from the smelting process. The Fractum Model 100 is a tool for breaking up the chunks, as it would be easier to move small chunks of slag (e.g.: use a regular front-end loader). Deskulling is the process of emptying a slag pot where things have already cooled to the point of where they aren't easily removed from the slag pot.
That's just a guess, though.
Joel Bennett it doesnt looks like an uneducated guess
I work in the agriculture industry, so I'd say it is a pretty uneducated guess. :P
My thoughts also! :P
Now 1.3 million views.
When you smelt iron ore the melt separates into two parts: iron and lava rock. The molten iron sinks to the bottom of the melt and the molten lava floats on top. The lava is a waste product and is either skimmed or drained off the top of the melt and is removed for disposal as slag.
Somehow that looks like the most satisfying job in the Universe right now.

@@danielthoman7324 Thank you for the info, much appreciated.
At my previous job they had this underground pits where the crane dumps orange hot semi hardened slag in. Then they lower the lid like a toilet seat, and spray water from the lid and suck out the steam through the chimney through an underground tunnel. The temperature shock turns slag into loose rubble and sand, then they use an excavator to manually scoop them out into a truck. Then it gets sent to a yard where they run it through a conveyor that separates still usable iron out and filters the rest by size. Much of it done without external contractors. Really precarious builds, but they work lol. Obviously nobody calculated anything so from there we do continuous adjustments and improvement such as hand rails, making walkways stronger, adjusting the angle of the mesh, etc. But theres this crazy situation on the vibrator feeder below a hopper. This one hook on the trough keeps breaking at the exact same spot and people just kept welding on bent pieces of rebar, which then breaks again, just like the original hook. At least 4 broken off bits of the same design welded one atop another, yet nobody thought maybe they should do an upside down U shape or just try something else so it doesnt keep breaking. Anyways idk what they do with the slag but the dust and skull with iron in them gets fed back into the furnaces.

I imagine if they didn't break it apart, it would take days, possibly weeks, for the center to cool to ambient temperature.
It's a long way2 vector if use rock en rolls(OrangeClockworks!!AngusAus!)
It would only take a couple days. The outer crust acts as a heat sink instead of an insulator. So it is actively drawing out the heat. You can see how thick the crust was already and that is just after a few hours.
It's an interesting though. Consider that earth is somewhat similar to this slag lump, except about 4 million times larger in diameter (assuming 3m diameter slag) but earth is still glowing hot inside after more than 4 billion years.

It looks so warm and snug, I just want to jump in and roll around.
I'll put that on my bucket list, somewhere near the bottom.
when it broke open I half expected a Superman villain to come walking out of the center and the video turns into a trailer for another Avengers movie
Huh,Eons,eh,maybe you TV,get a Sky box curl verCoAX,dishABoutUmayGet2SeeOvaLooks!?
You could watch engineers empty slag in to a ravine when Bethlehem Steel was in operation. That was a sight to see, my old man is a rail fan, he use to take me trainspotting all the time as a child and watching slag being dumped was one of those things.
We have a magnesium plant.. I love the green slag they use to sell for driveway gravel
The stuff apparently is sold as blasting grit. It is mainly magnesium orthosilicate.
When that thing busted open I wanted so bad for Chuck Norris to slowly rise up to full height right out of its molten core.
this guy has a lot of patience.
I imagine a bunch of hungry steel mill workers just outside of frame, eagerly waiting, each with a hot dog on the end of a stick.
8 years later gets recommended to me. now I know a chunk of slag is called a skull. So the magma inside is brain?
My grampa had a steel mill in Indiana, when I was a kid, I could go watch all the glowing stuff being poured and rolled. Even far away, it would feel hotter than standing in the sun.
can someone explain what I just watched?
Kevin Klika a pot of oxidized junk from a steel mill. It was cooled on the outside so the could slide it out like sliding a muffin out of a muffin pan, but the inside is still hot because it takes forever to cool down.
Cooking of strawberry muffin
+Screwg oogle good explaining
Hillary ordered a new anal plug for Anthony...
oh my goodness a political reference, you are so funny!
When the big V12 opens up the molten core, it's pretty satisfying.
"Cracking a Dragons egg"
I imagine that's what cracking a dragon's egg would be like...
It's called skull? That is so metal! (get it?)
Hatagashira Nope. Explain.
Simmons That's also pretty metal.
+acid junkie Slag is produced from smelting metal
When I was a boy in the 60s I used to watch the trains tipping slag from the crucibles at Ravenscraig/Corvalls British Steel works in Motherwell from my Grans flat, it was amazing, it used to light up the sky like daylight.
That's hot.
Never would I think to see a guy walking around a Steel/Iron mill in shorts 🩳
The title doesnt make any sense to me but I still had to watch this
Slag is the impurities from the steelmaking process. This pot was where they transported the slag in. Now they dumped it out, along with the refractory lining of the pot, and are breaking it up so it cools. Slag can be recycled into road materials or other usual when it is cooled and ground up. You're welcome, from a lady engineer.
"Good work Miners, Get that Ommoran core loaded and lets wrap up this mission."
"ROCK AND STONE!"
"WHOOO!"
"IF YOU DON'T ROCK AND STONE, YOU AIN'T GOIN' HOME!"
"MUSHROOM!"
And now this just comes up when opening yt. Love those algorithms 🤣
Mine am Iron Man!! ParaNoIDzzzz,Boston tea party?
Its like those chocolate covered cherries your grandma always gives you.
who else watched this video because they had NO FUCKING CLUE what on earth the title meant? lol it got me too curious....kinda like 2 girls one cup yet not gross haha
I fucking love metallurgy and metal works.
For those who have no idea what we just watched, a bit of context would have been appreciated 😄.
Steve Waclo Slag, a waste product of ore refinement and steel production is collected in slag pots. Cooled slag is often metallic glass in appearance and is fairly dense. After it's tipped from the slag pot, it must be broken into manageable pieces and allowed to cool. The mechanism resting against the slag mass is a guide for a steel rod used to split the slag so that it can disposed of, probably, by a front loader.
+Thanks Justin! That 411 was probably also buried somewhere in the 400+ comments! but I'm lazy. Although, I have discovered that scanning comments quickly, picking out anything exceeding one line, is often a worthwhile exercise. There should be a way to move highly liked comments to the top!
I like it when big processes are just big versions of small processes
I always wondered what happens to the slag when cleaned out of these slag pits. The slag left over is basically obsidian and various metallic oxides, that are hard and abrasive material . So I always wondered if this material would be crushed down to make abrasives or something rather than just being dumped somewhere, or if it could be turned into some sort of insulation or rockwool. My local municipality does not allow glass and certain materials in our landfills for this purpose because it does not break down and this steel slag would be basically the same thing. So hopefully it was repurposed in some way. But then again this is Big industry and companies making millions of dollars don't care about these kind of things and find ways around it kind of like Safelite Auto glass. They claim to recycle all of the glass windshields that come into their place and classify themselves as a green operation because of this. Funny thing is you can go to almost any Safelite Auto Glass store and find the dumpster out back that goes to your landfill; full of broken windshields. I actually have photographic evidence of this from when I had my windshield replaced and went to throw something in the dumpster while I was waiting. When I asked the manager about this, his excuse was that they can only recycle OEM glass because aftermarket glass cannot be made into a new windshield. That was the first lie because that window was the original window for my vehicle and it was OEM, and later that night when I went back to the shop I was able to verify that my windshield was in that dumpster I was able to verify this because of the inspection sticker cut out that matched perfectly. My argument was that glass is indefinitely recyclable and so his answer makes no sense and even if it couldn't be made into a new windshield; that it could be made into things like concrete aggregate, fiberglass insulation material, and abrasives, and many other things which Safelite claims to do being partnered with Shark industries and Owens Corning fiberglass. Then I informed him of my local municipality having ordinances behind glass waste in residential trash and that that dumpster was in violation and a simple phone call could get them a hefty fine. They will never admit it; but I got an email later that night after my online complaint from someone higher up actually offering me all kinds of promos, discounts, and even refund for my service they would just need me to esign some paperwork. Basically they were offering me hush money to keep my mouth shut and the e-signature would probably have been put on a non-disclosure. I didn't take it and put a Google review with the photos of the windshields in a residential dumpster along with the location of the branch that was doing it up on the internet. The next week when I drove by the place I found that they had a new garbage company; as waste management, the company they were working with, dumped them 🤣🤣. I'm sure they're still doing it though so I was only able to make a difference for a couple of months 🤷 but hey it was worth it.
Chatwall! Use line breaks and paragraphs!
@@Shinzon23 wasn't aware I needed to cater to your reading preferences. Oh I forgot this is 2022 people think they're entitled to tell people how to speak, how to write, how to think, how to live, etc. Get bent
@@jerichojoe307 Wow... someone makes a useful suggestion to use line breaks and paragraphs so people's eyes aren't glazing over trying to read an entire wall of chat and yet you're chewing me out... because you're old and crusty.... I think?
If anyone, you should be the one "getting bent",as you put it.

I LOVE content like this. It’s why I’m not as successful in life!
Ничего не понял, но очень интересно.
Это шлак с доменной печи так сказать пенка когда варят металл .в таких кувшинах вагонах вывозят из печи и выливают в яму затем тушки водой .только они наверное долго его везли что он остыл потом его дробь на фракции и получается строительный материал.
