Steelmaking Process - an overview | ScienceDirect Topics

In the steelmaking process that uses an electric arc furnace, the primary raw material is scrap metal. The scrap metal is melted and refined using electrical energy. During melting, oxidation of phosphorus, silicon, manganese, carbon, and other materials occurs, and a slag containing some of these oxidation products forms on top of the molten metal. Oxygen is used to decarburize the molten ...
