DC electric arc furnace – IspatGuru

May 15, 2013 · DC electric arc furnace. DC (direct current) arc furnace is a furnace for steel making which represents a different concept in the designs of arc furnaces. Generally DC arc furnaces have single graphite electrode (cathode) and the current flows down from this graphite electrode to an anode which is mounted in the bottom of the furnace. .
