Abstract: PURPOSE:To decrease the oscillation of the molten Al layer on the bottom cathode in an electrolytic cell for Al and the curving of the layer surface by constituting said cathode of carbonaceous units having conductivities different in the right and left directions of the centerline of the furnace. CONSTITUTION:DC is conducted between carbonaceous anodes 3 suspended from above on an electrode bath 5 in an electrolytic cell for Al and a cathode 12 consisting of the carbonaceous unit in the bottom of the cell to electrolyze the Al2O3 in the bath 5, thereby forming molten Al 6 on the cathode 12.
