An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking. Arc furnaces used in research laboratories and by ...
Electric arc furnaces (EAFs), which apply current to the metal via electrodes over an electric arc. The Flodin furnace is an early EAF, specially designed to smelt iron from ore through the direct addition of carbon; Electric induction furnaces, which heat the metal through eddy currents, requiring metal mostly free of gangue and corrosion
To supply its mills, Nucor uses electric arc furnaces and continuous casting to melt scrap steel as opposed to blast furnaces to melt iron. In 2023, the company produced and sold approximately 18.5 million tons of steel and recycled 18.4 million tons of scrap. [1] None of Nucor's mills are unionized and the corporate culture is opposed to trade ...
Their furnaces were electric arc smelters, one of the first viable methods for extracting metals. The businesses of the era dramatically increased the supply of aluminium, a valuable element not found in nature in pure form, and reduced its price.
1941 electric arc furnace During the 1990s, Crucible expanded its operations to Canada, working with General Motors , and building a 35,000-square-foot (3,300 m 2 ) facility with newly patented smelting and processing equipment costing $25 million.

The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys. The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.
