Electric Arc Furnace (EAF) - HarbisonWalker International

The electric arc furnace (EAF) is the major producer of hot metal in the steel industry today. There are two types of EAFs: alternating current (AC) and direct current (DC). AC EAFs have three electrodes, while DC EAFs have two: a cathode, which is a single electrode in the roof of the furnace, and an anode in the bottom of the furnace.
