<p>A direct current smelting furnace is disclosed. The anode and cathode are series connected electrodes, both of which are immersed in the furnace charge. A plurality of pairs of electrodes is preferably employed, and switching means are provided so that each pair of electrodes can be switched independently of the other. In this manner, four separate electrode arrangements can be achieved with the anode and the cathode switching position to ensure more even wear of the electrodes. The arrangement of the present invention has substantial advantage over known direct current and alternating current furnace arrangement.</p> |
