Abstract
An anode for a direct current arc furnace is proposed, in which at least part of the area of the furnace receiving the melt is provided on the inside with an electrically conductive refractory lining, which is electrically connected to the conductor located on the outside and in which a cathode is positioned vertically above the melt. The electrically conductive lining (3, 4; 9) and/or the conductor (1, 8) have varying values with respect to their electrical characteristics in the circumferential direction relative to the vertical axis of the cathode (2; 11), so that there is a planned, asymmetrical current distribution on the furnace bottom.
