LINING FOR AN ALUMINIUM ELECTROLYZER HAVING INERT ANODES

摘要

The invention relates to a lining for an aluminium electrolyzer. The lining for an aluminium electrolyzer having inert anodes and being enclosed in a cathode casing comprises a bottom formed from taller bottom blocks having projections and shorter bottom blocks, the shorter bottom blocks being mounted at the ends of the bottom of the cathode device, wherein the shorter bottom blocks alternate with the taller bottom blocks having projections, and vertical channels are provided in the projections of the blocks over the entire thickness of the block for the mounting of conductive elements formed from aluminium and attached in the lower part to a current-carrying collector that is in the form of a plate which extends out of the ends of the bottom blocks and through the longitudinal sides of the cathode casing. This reduces the amount of heat extracted by the conductive aluminium elements and results in stable electrical resistance of the conductive elements over the course of the entire service life of the electrolyzer.
