  • Patent number: 10246790
    Abstract: The invention relates to electrowinning of aluminum from cryolite-alumina melts, and can be used in the shunt design of a cathode assembly. In an aluminum electrolysis cell, cathode vertical metal shunts, are designed such that their top part is melted aluminum, and the bottom part is solid aluminum. Shunts are located in conduits made in a hearth slab lining which has a widening in the middle part which is wider than both parts of the shunts. The widening in the shunt conduit can be filled with a composite material, i.e. titanium diboride-carbon. The shunts can be designed as a tube, and the widening in the conduit and the space inside the tube can be filled with the composite material titanium diboride-carbon. The invention makes it possible to increase the electrical efficiency due to the absence of contact assemblies, reduced current loss, and achieving an effective current distribution and current shunting.
