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.

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.

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 😳

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

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.

Electric arc furnaces typically use each year the equivalent power needed for up to 200,000 homes
@OffGridInvestor
@OffGridInvestor 5 месяцев назад
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.

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
@michaellynch1018 10 месяцев назад
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

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
@brettbledsoe8154 7 месяцев назад
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.

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.

Why don't the electrodes melt?
@JamesSwordResearch
@JamesSwordResearch Год назад
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.
