Steelmaking in Electric Arc Furnace

Steelmaking in Electric Arc Furnace Though De Laval had patented an electric furnace for the melting and the refining iron in 1892 and Heroult had demonstrated electric arc melting of ferro-alloys between 1888 and 1892, the first industrial electric arc furnace (EAF) steelmaking process only came into operation in 1900. Development was rapid and there …
