CATHODES FOR ALUMINIUM ELECTROLYSIS CELL WITH NON-PLANAR SLOT DESIGN

机译:非平面槽设计的铝电解槽阴极

摘要

Cathodes (1) for aluminium electrolysis cells consisting of cathode blocks (4) and current collector bars (2) attached to those blocks whereas the cathode slots (3) receiving the collector bar have a higher depth at the center than at both lateral edges of the cathode block. Additionally, the collector bar thickness is higher at the center than at both lateral edges of the cathode block. This cathode design provides a more even current distribution and, thus, a longer useful lifetime of such cathodes and increased cell productivity.
