Another steelmaking process widely used today is the electric furnace. The furnace charge is generally 100 percent scrap and an electric arc is used as the heat source for the refining process. The electric furnace is generally not used for deep drawing steel or very light gauge steel because of its inability to reduce the residual element In the mini-mill process high-grade steel scrap is combined with pig iron hot briquetted iron (HBI) and other metals and melted at a temperature of approximately 3 000 degrees Fahrenheit in an electric-arc furnace (EAF).

Characteristics of Electric Arc Furnace Steelmaking
Electric arc furnace steelmaking mainly uses arc heat and the temperature in the arc action zone is as high as 4000 °C. The smelting process is generally divided into a melting period an oxidation period and a reduction period. In the furnace not only an oxidizing atmosphere but also a reducing atmosphere can be caused so the efficiency of dephosphorization and desulfurization is high.
