摘要： A direct current arc furnace has at least one anode movable into the furnace interior and at least one cathode also movable from above into the furnace interior, between which cathode and the inserted material or the melt an arc is produced. The anode contains a cooling system in its interior having a controller which cools at least the immersion region of the anode to a temperature which is lower than the temperature of the melt.This furnace device and the anode are utilized in methods for melting and heating of materials with advantage, at least the immersion region of the anode being maintained at a temperature which lies below the temperature of the melt.
