- I'm going to use special hell fuel for melting iron. The main reason of doing this is really high iron melting point. Therefore, I'll mix charcoal, coal and coke to get the highest possible temperature. I hope to reach 1500 °C (2732 °F).

Very interesting I would love to see the next video that’s some scary temperatures you’re talking about. Remember BSafe my friend take care😁👍🏻
Temperatures are really high! In the past I didn't know that it's possible to get such high temperatures without professional equipment at home 😀 It's already done and I was extremely caution because I didn't reach such high temperature in the past.
Very useful, this is exactly what I was looking! Thank you man!
You're welcome. Good luck in melting.
Brilliant! 😄 Just what I was looking for💪💪💪👍👍
Glad to help ;) A little bit more work than with propane burner but much easier to rich very high temperature
I normally don't like music in videos but this time I absolutely loved it :D
Yes, like from beginning of 20th centuries for black and white movies without audio ;)
@@DuralMetalurg exactly!! Love the content :D
@@nick_steele9790 Thanks
Particle boards burn hot enough to melt steel also. They literally melted nails in my rocket stove.
have you thought of putting small tubes into the middle of the tweres and injecting used motor oil into the furnace with the air stream? With just a charcoal fuel seems like it would add to the heat. I figure I will try that in time, when I get around to firing my cupolas. I don't have ready access to coke or hard coal, but I can make as much charcoal as needed, and I'd like to see if I can get enough heat to melt steel scrap. It supposedly turns back into iron with the carbon from coke or charcoal added to it.
It's interesting idea but if you want to make hybrid system it won't be easy. It's always easier to make furnace on one fuel: charcoal (coal, coke), propane, oil or electricity. It's complex engineering project to make it work and be efficient. Anyway I'm sure that it's possible and I hope you'll succeed!
great vid! i think for the mixing im going to use a cement mixer with a saleable lid may be though
It will work for sure
OK! Let's go! :D
How do you get coke? I would have expected this is hard for an individual to get.
Basically yes, but it's produced in the city which is not far away from me. I was given several kilograms. I don't have a lot and usually coal is enough for everything.
@Doggo Blaster Free fuel is great! :)
Question: Where can I buy that crucible that works in a coal forge. Can't find it on the internet. Thanks. Brand and store please.
It's very easy. I bought both crucibles on Ebay. I don't remember the seller but there's plenty you can choose from. Just type "crucible"! And I don't think the one I bought even is a branded product. But quality is very good!
Interesting, ive only thought about this on an industrial level. Time to figure out how to get coke.
Yes, several years ago, I wasn't sure that this is possible as well 😀. Coke is produced in my region, so I could get a little bit. In fact, you can melt iron even using only charcoal + coal (different types of coal allow to reach different temperature). Coke allows to make this much faster.
Ah i see, makes sense. Luckily for me, i live in an old coal mining town, and theres tons of coal slag around. It burns plenty hot, and its basicaly everywhere
Yeah, such location is good for you. In the past I've got messages from people who live very far from coal mines and in suck places it's really hard to get even expensive coal 😉 As I've showed in my video coal allows to get about 2100 C. Of course it's really hard to reach so high temperature but 1500 C is possible.
Once the burn ban is lifted, im going to build a new forge, since my old one is falling appart. Id like to get into forging, and making knives and stuff. As for the coal, most of it here is leftover and not the highest quallity, but it does burn well. In fact, i have acheived very high temperatures with it. I have melted iron on accident, however it is still too difficult to controll. I think with a new forge will enable the heat to be harnessed more effectively, and allow for bigger and better projects. :)
Good luck with your new forge! :)
Have you ever considered using a hopper full of powdered coal dispensing powdered fuel into a tube with forced air to create a more efficient burn? I have been researching powdered coal burners for a while now but I haven't found anybody who has actually tried this on a small scale. Would it work for melting steel?
When I worked for iron and steel works burners used mixture of natural gas and powdered coal. As you say in a small scale it's a different story and might be harder to make it work. I wouldn't mind to try it.
@@DuralMetalurg The only think I'd be worried about is that it would just be gravity fed, and there'd be air in the hopper. If there was a blowback, you might have a bomb.
A pulverized coal set up would be awesome although for direct injection I would think you would need a deeper furnace to allow the heavier ash and clinker to accumulate below your crucible and possibly a way to control the hot fly ash out the top from causing issues plus a way of preheating the furnace and initially igniting the burner. Otherwise a pipe lined with 3000* refractory, 2 bouncy house blowers, powdered coal, a propane or oil fired ignition burner, and some redneck engineering would do it. You would need a hammer/roller mill that could pulverize the coal to the constancy of talc powder for either though
Interesting video! How do you get coal, everywhere I look they only sell charcoal.
Thanks. It depends where you live. In some countries it's easy to find because there are coal mines. In other countries or regions there is no local production, so it can be tricky :)
@@DuralMetalurg yea I thought so too... Well thanks for the fast reply and expect to see me on your other videos too! (I just found this channel)
@@low-keyforce7204 Sure. Thanks
Found this video and wondering if you sell that mixture? Would like to use it to burn out some tree stumps
Maybe in your case it's better to use some flammable liquids? This one is good particularly for melting and you need to supply air continuously. It's a simple mixture which is easy to make. The main idea is that fuel with lower ignition temperature starts fuel with higher ignition temperature.
Hi there, would this work for stainless and inconel?
I'll try that in the future. The higher the temperature the closer it to the crucible maximum allowed temperature. This furnace and coal definitely allows to get + several hundred more degrees.
That piece he was hammering the coke on looked like the piece of radio active material from Chernobyl
Sure Alton :) That's how it works in Ukraine. It would be to easy for me to go to shop and buy some steel products that were produced 60 kilometers from my home by a huge iron and steel works. That's ridiculous! In Europe we never look for easy solutions. I take my car and ride 700 km to Chernobyl, illegally cross Exclusion Zone, try to get rid of chasing guards and finally steal a piece of steel from nuclear reactor ;)
Ok, so I have a question, _why_ does coke burn hotter than charcoal? I'm really looking for a good answer.
secondly, how are the fumes/flames when working with _exclusively_ coal, vs the other two fuels? I would assume the coal would produce more smoke and gas, and fire etc.
lastly, what distinguishes a hot-burning charcoal from a not-so-hot-burning charcoal?
Hi. These are all very good questions but I might not have good answers ;) 1. Well, coke is made of coal. As I understand it has higher concentration of carbon. Charcoal is wood that was burnt without reaction with oxygen. Density and carbon concentration of charcoal is much smaller than in coal and coke. If we talk about coal than it took million years and pressure to form coal under the soil. 2. Fumes and flame depend on the grade of coal. There are a lot of grades of coal and they give very different temperature and fumes. 3. I don't know about hot burning charcoal. I made mine by myself. No pressure, no special techniques.
@@DuralMetalurg thanks for the reply! I'm trying to design a carbon powered high-temperature torch based on a custom design I came up with, and I need to find the most energy dense form of carbon for the project. I believe I can make charcoal myself, and then grind it to a powder, and crush it to form a much denser piece of high purity carbon.
It is not a suprise for most of us because we are using a mixture of charcoal and coal for silver smelting . Dramatically charcoal gives enough heat for burning coal and coal gives enough time to melt metal..😎
100% right but for melting silver you need less than 1000 C and for Iron 1300-1400 C ;) In the same time UA-cam watch people with different background and I believe it can be useful for some of them ;)
I would use anthracite coal for melting metal because it burns hotter than charcoal
That's why I use coal and coke with charcoal. This way charcoal is the ignition source for coal and coke. As far as I know anthracite is a grade of coal.
Anthracite is indeed a very high quality Coal. I live in the South Wales Valleys built upon the backs of magnificent men working an Anthracite seam... it is Hard coal, almost metallic, very high carbon content with very few impurities. The Royal Navy prized it before it shifted to Oil fired ships. It even helped Steam trains with small fire boxes overcome design deficiences of having a too large boiler...Poor quality coal would result in an anemic steam train that couldn't pull decent loads.
in my country we only have the first kind of coal, the rest has no name and doesnt exist, cant even be translated to french. do i have to come to usa to melt steel.
Bonjour! You actually do have the name for coal. It is "houille" or it looks like "charbon" is a synonym as well. Charcoal is "charbon de bois". Well coke is the same in French. You had multiple coal mines for centuries. For example, Nord-Pas de Calais Mining Basin. It looks like now everything is closed. Some countries got rid of their coal mines completely. Many European countries still have coal mines, so you don't have to go as far as the USA if you don't want to. This particular video was made by me at home in Ukraine and there you can buy as much as you want to. I had multiple transit flights through Paris airport when I traveled from Canada to Ukraine and back. As far as I remember just about 2.5 hours from Paris to Kyiv ;) P.S. It looks like Spain just started to close coal mines, so there is still a slight chance to buy some close to your country border :)
I’m sorry but what exactly is coke in this context ?
Here you go. Copied this explanaitation from Wikipedia: Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air-a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
Если у тебя есть кокс - сделай вагранку и всё. Можно плавить БОЛЬШЕ чугуна и не так гиморно имхо.
Я понимаю, но у меня то не промышленные масштабы. Хобби 🙂
I don't get it! If you want really high temperatures, and coke burns at the highest temperature, them why dilute the mix with lower-temperature-burning charcoal & coal? They will just lower the final temperature, surely! The one reason you give is that the 3 fuels have different ignition temperatures. Well, then why not start a chrcoal fire, and then load coke on top? The charcoal flame seems plenty hot enough to ignite the coke. Am I missing something?
It didn't work really good for me when I did the way you said. I start furnace with charcoal anyway but because of high ignition temperature (especially coke) some pieces of it didn't burn at all. Small pieces of different types of coal which are mixed together just work the best. It allows to melt really fast with high temperature. The temperature is not the highest on the top layer if furnace is loaded with charcoal because the air which supplies from the bottom doesn't get so high. May be with different furnace or air supply system the other technique will work better but for this furnace this mixture is the best solution
The mix will light more evenly at a lower temperature and heat up to coke temps faster. The air comes into the furnace from the side, not the bottom. In a super efficient furnace, this theory would work well. In an old steel drum with a pipe in the side, however, mixing up a hot burning fuel with a low ignition temp is an extremely simple way to heat things up fast.
Once it's lit, though, you'll get better results with straight coke, though.
holy hell, 4500 degrees... i wonder how hot anthracite burns with forced air...
Sorry I don't remember where I mentioned 4500... Probably I could make this note as maximum possible for anthracite. About 2200 C is close to maximum you can get. I used forced air. My furnace works by blowing air using the vacuum cleaner and there is burner inside the furnace. It's not just connected pipe. So i use forced air and if you mean using pure Oxygen than probably it can help a lot.
You are from Russia with love? 😂 Russian men are very curious about metallurgy & machine tools.
What does he mean by coke
He means what this word means in metallurgy. You can find the meaning of this word in Wikipedia under coke (fuel). I copied the description for you: "Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air-a destructive distillation process."
@@DuralMetalurgthanks 😊
@@empirorstages You're welcome ;)
I just wasted 4 and a half minutes of my life waiting for nothing all I got is to be continued when you about to melt the coal
Why bother and waste even more time writing a comment? When you watch Netflix or TV and don't like something you start to send mails, messages, call them to tell that you don't like something?
Charcoal burns way hotter than that
Ok. What temperature did you get?
@@DuralMetalurg I’ve melted steel in my charcoal forge so it is above 1300 and I doubt I got perfect combustion. No shade on the mix this is the best fuel for melting still I just have a lot of trouble buying coal in Australia
@@fostersstubbyasmr9557 I see. My homemade charcoal doesn't allow me to reach temperature for melting iron. I mean I can melt my steel crucible and pipe I use for blowing air but it's not enough to melt a couple kilograms, so I started to use coal. With coal I can melt bronze in half an hour and with charcoal it takes me 3 times longer
Just use coke
