  • Cathode construction
    Patent number: 6113756
    Abstract: An electrolytic reduction cell for production of a metal includes an outer steel shell, a layer of insulating material adjacent the outer steel shell and a carbonaceous layer overlaying the insulating material and protecting the insulating material from an electrolytic bath to be contained in the cell. The carbonaceous layer includes at least one carbonaceous cathode block having an upper surface and a lower surface, with a plurality of electrical contact plugs being mounted in electrical contact with the lower surface of the cathode block. A collector plate is in electrical contact with the electrical contact plugs. The electrical contact plugs are distributed over the lower surface of the cathode block such that in operation of the cell, a substantially isopotential surface is achieved at the top surface of the cathode block.
