ABSTRACT:
The invention comprises an improved Hall cell for electrolytic reduction of aluminum from a molten salt bath having a carbon cathode bottom wall and sidewall, a cover over said cell, at least one anode within said cell depending from an anode support rod passing through said cover, conductive means over the carbon bottom wall to reduce the spacing between the anode and the cathode, and protective sidewall lining means relatively inert to attack by the molten salt bath on the inner surface of the carbon sidewall. Cooling means are provided to cool an upper portion of the sidewall lining adjacent the surface of the molten salt bath to promote the formation of a protective layer of frozen bath over the exposed portion of the sidewall lining adjacent the surface of the molten salt bath while retaining within the cell at least a portion of the heat removed from the sidewall lining.
