A Detailed Explanation of the Electric Arc Furnace - What It is and How It Works

An electric arc furnace is a high-temperature furnace, that uses high-voltage electric currents as its primary element, and the electric arc is produced between the electrodes. This Electric arc is used for melting the metal.
Invented in France in 1907, this furnace is a crucial part of iron and steel recycling operations.
There are mainly three main types of electric arc furnaces. They are;
▶ Direct electric arc furnace
▶ Indirect electric arc furnace
▶ Submerged electric arc furnace
The main parts of the electric arc furnace are the roof, hearth (lower part of the furnace, where molten metal is collected), electrodes, and side wall.
The working principles of an electric arc furnace include charging the electrodes, melting the metal, and refining.

Till you stood near one, you will never understand how loud the arc is!

[@SolarPatrol]

That's crazy! Still using them over 100 years later.

Brings back memories hated fishing out a broken stick or making a fresh Launder with Guntapite good money though

Miss those days on the furnace ! 😔

[@keithlewis9106]

We used DC and the voltage was one electrode and bottom was the discharge . 200 tons in 45 minutes.

[@Chinagraphiteelectrodeproducti]

你好，我来自中国，我是中国石墨电极生产厂家出口贸易，现在石墨电极价格便宜，需要采购吗 ？

[@colwem]

what do you mean when you said indirect arc furnace is used for "melting of non-ferrous metals, iron foundries etc" That makes no sense. Iron is the definition of ferrous. It's contradictory.

[@Dinkledorpher]

Very good description.

[@superslashcd]

Is the grades of steel made in an electric arc furnace worse than a blast furnace then? Can you make specialist steels?

[@jamesraymond1158]

Very interesting. What are typical voltages and currents? How many kwh does a typical plant consume in a day?

[@Bonadio2009]

900VAC between phases. 45kA.
A typical transformer for a medium sized furnace is rated for 60MVA.

[@shrimpshot1581]

I know there’s one that has an entire hydroelectric dam dedicated to it

[@djscrizzle]

Evraz here in Pueblo, Colo is just 2 miles from Xcel Energy's Comanche Generating Station. They take their power right off the buss bars at the power plant at 230kV. That furnace is a 40 ton size. Three of them in their plant can be fired up depending on demand.

[@rawpuredata3072]

Electric arc furnaces typically use each year the equivalent power needed for up to 200,000 homes

[@OffGridInvestor]

Shockingly high amounts. Quite a few have their own dedicated power station. There was a system similar to this doing aluminium owned by alcoa near me. 80kms away like 48 miles, they had a coal power station that ran it and had pylons going back to the smelter. Guys tell me when you were 80 yards from the pot and carrying a shovel, you could feel a magnetic force trying to pull the shovel towards the pots.

[@jimwilloughby]

Good explanation, but how long do the electrodes last?

[@CesarGamezT]

a few heats, depends on many factors, but usually a new segment is added every 20 to 30 heats.

[@lavishwhisper6753]

I’ve watched a few of these videos now, and I can’t understand how there are always guys walking around these explosive beasts!?? The sheer noise, heat, flying sparks, gaseous byproducts...why would a human being need to be even remotely close to these things?
Electricity scares (& fascinates) the heck out of me 😳

[@sebastianlesny2230]

once you get a taste of working with it around trustworthy, educated people the interest becomes addicting.

[@razadaza9651]

This is used to process silica for solar cells too

[@NitrousXProductions]

The cons where it produces hydrogen and nitrogen gases could they not be captured then be repurposed for fuelling the electric arc furnace. Meaning that it would be more economically efficient

[@michaellynch1018]

The hydrogen and nitrogen mostly appear dissolved in the steel itself or get sucked away with the other waste gases and dust that come off when the furnace is running. It would be possible yes, but very very inefficient and would be very expensive

[@challengeforgift3367]

Does it heats the air ? How much

[@Zamphirix]

The one I worked around typically made it around 30-40 degrees hotter than the temperature outside. The surface temperature of the outer shell was around 400 degrees.

[@teddysponsler6220]

I'm looking todo an smaller one, an 1/8 of the size of this one., fully automated.

[@cymbala6208]

👍

[@recyclinggestapo6943]

Why don't the electrodes melt?

[@JamesSwordResearch]

The electrodes are made of graphite. Graphite has very high heat resistance, and can handle the heavy current and intense heat required to melt the steel material.

[@recyclinggestapo6943]

[@shermanyoung8185]

The drawback with the EAF process is that it can't mass produce flat roll sheet automotive steel that's why Cleveland Cliffs blast furnace to BOF furnaces are the number one supplier of automotive roll sheet steel in North America and United States steel is probably number #2🧑‍🏭

[@brettbledsoe8154]

This is going to start changing very soon though. Nucor is building a sheet mill in West Virginia that will be an EAF with incredible capabilities including supplying automotive roll sheet. I work for them so you could say I’m bias, but I believe we’re going to change the industry.
