摘要：
A DC electric arc furnace having laterally offset hearth and arcing electrodes, has the arcing electric power for one of the electrodes carried by a conductor arranged with respect to the furnace hearth to provide an electric field within the furnace and which bucks the field created by the offset electrodes so that the arc formed within the furnace is vertically oriented.
