ABSTRACT:
An alumina reduction cell is described in which a bed of holow refractory hard metal (RHM) shapes form a packed cathode bed above the carbonaceous cell cathode and within the molten aluminum pad. This packed bed permits free flow of the molten aluminum and reduces RHM material usage as compared to known packed bed cells.
