Electric Steelmaking Plants

Electric Arc Furnace (EAF, employed for large productions): In arc furnaces, which are the most used in an industrial way, a powerful electric arc is created between the electrodes and the scrap load taking advantage of the heat generated by the arc itself. There are two major techniques, based on AC and three electrodes, in addition to the DC

Electric Arc Furnace Process - an overview | ScienceDirect Topics

Modern steelmaking is an integrated process consisting of blast furnace (BF) ironmaking and basic oxygen furnace (BOF) or electric arc furnace (EAF) steelmaking. Molten steel from BOF or EAF process can undergo a secondary refining process in a ladle furnace, or be sent directly to the continuous caster.
