Date Jun. 6, 1996A d.c. arc furnace for metallurgical purposes includes two or more electrodes arranged on the furnace vessel and projecting into the furnace vessel. To avoid actions of forces departing from the magnetic fields derived form the currents conducted to the electrodes and effecting deflections of the electric arcs, the electric supply means provided for each of the electrodes are each arranged in the immediate vicinity of the electrode to be supplied, the electric supply means of one electrode being arranged so as to be spacially separated from the electric supply means of the remaining electrodes, viewed in the peripheral direction of the furnace vessel.
