PROCESS OF PRODUCTION OF ALUMINIUM BY ELECTROLYSIS OF CRYOLITE-ALUMINA MELT AND ELECTROLYZER FOR ITS IMPLEMENTATION

摘要

FIELD: production of metal aluminium. SUBSTANCE: periphery of liquid cathode is screened by diaphragm placed under liquid cathode. Current is supplied to additional layer of molten aluminium located under diaphragm which leads to suppression of convection of molten aluminium. EFFECT: increased efficiency of process. 9 cl, 5 dwg
