ABSTRACT:
A forehearth in a melting furnace is arranged with groups of electrodes and with each group having at least a pair of opposed electrodes. The opposed electrodes are connected to a multiphase power source so that the phase relationship between groups of adjacent electrodes along the forehearth is 90.degree. or less and typically 60.degree.. The electrode groups may be arranged along the path of molten material movement in the forehearth and may be arranged to generate and produce a current across the forehearth. The electrodes may be arranged to enter from the bottom, side or top of the forehearth channel.
