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.

found some crazy video of an arc furnace and immediately had to look it up lol

[killmimes]

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.

[affectionatepunch]

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

[nigel]

AND CAN’T BE POWERED BY WINDMILLS… SOLAR PANELS… RAINBOWS… UNICORNS… OR WET DREAMS.

[keithlewis]

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

[lavishwhisper]

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 😳

[jimwilloughby]

Good explanation, but how long do the electrodes last?

[jamesraymond]

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

[razadaza]

This is used to process silica for solar cells too

[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.

[shermanyoung]

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🧑‍🏭

[superslashcd]

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

[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

[teddysponsler]

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

[alozano]

Union Carbide in Mexico use coke to make electrodes

[timgaming]

I need pdf on that where can I get one

[PrimitiveProcess]

100% recycling all slags. We need sustainable and environmentally friendly technology-Steel Slag Processing.
