based on the types of electric current, alternating current (AC) EAF and direct current (DC) EAF. In an AC-EAF, the electric current passes from one elec-trode through an arc to metal charge, and then goes up to another electrode. In the DC-EAF, typically a single elec-trode is in the roof and the other elec-trode is in the bottom of the furnace.
