The project of diversion of aluminium electrolysis cell cathode

摘要

Abstract invention patent: "project of diversion of aluminium electrolysis cell cathode of the present invention relates to non-ferrous metallurgy, more particularly, to electrolytic extraction of aluminum from criolita fused alumina, and can be used in the project. Deviation from a cathode assembly.In an electrolytic cell for aluminium, deviations of vertical metal cathodes, which conduct electrical current from the molten aluminum to the Links toolbar of cathode, are designed so that the upper part of such deviations are cast aluminum and the lower part for The solid aluminum.The deviations are located in the conduits made in a finishing bottom slab with an enlargement in the central part which is wider than both sides of the deviations. The enlargement in the conduit diversion may be filled with a composite material, that is, diboreto of titanium carbide.The deviations can be designed as a tube, and the enlargement in the conduit and the space in the interior of the tube can be filled with the composite material diboreto of titanium carbide.The application of the solution proposed technique makes possible a significant increase in the electrical efficiency due to the absence of contact assemblies which contain materials dissimilar in the diversion of cathode, the loss of power is reduced and the range of a current distribution effective Gara Ntida and deviation of current effectively.
