Abstract:
1. An electrolytic oxide reduction system, comprising: a plurality of anode assemblies, each anode assembly including a plurality of anode rods having the same orientation and arranged so as to be within the same plane; a plurality of cathode assemblies alternately arranged with the plurality of anode assemblies such that each cathode assembly is flanked by two anode assemblies, each cathode assembly being in planar form, the plurality of anode and cathode assemblies including lift tabs protruding from side ends thereof; and a lift system including lift cups configured to selectively engage one or more of the plurality of anode assemblies, the plurality of cathode assemblies, or a combination thereof, the lift cups of the lift system being aligned with the lift tabs of the plurality of anode and cathode assemblies, each of the lift cups configured to independently rotate around a corresponding lift tab so as to be above the corresponding lift tab in a disengaged state and under the corresponding lift tab in an engaged state, wherein each of the lift cups includes a concave surface and an opposing convex surface, the concave surface facing a top surface of the corresponding lift tab during the disengaged state, the concave surface facing a bottom surface of the corresponding lift tab during the engaged state, the concave surface configured to receive and support the corresponding lift tab during lifting, the convex surface facing away from the top surface of the corresponding lift tab during the disengaged state, the convex surface facing away from the bottom surface of the corresponding lift tab during the engaged state.
