Катодное устройство алюминиевого электролизера

摘要

FIELD: non-ferrous metallurgy; electrolytic production of aluminum. SUBSTANCE: proposed cathode unit includes detachable lined metal bath mounted inside framework formed by transversal stiffening members interconnected by means of longitudinal stiffening strakes, end stiffening strakes and compensating members made in form of metal plates mounted between walls of metal bath and framework. Transversal stiffening members are made in form of frames at differential strength characteristics over length; compensating members are mounted perpendicularly relative to walls of metal bath and are rigidly secured with inner webs frames; end stiffening members are secured on metal bath. End stiffening strakes are made in form of isosceles prisms. EFFECT: enhanced strength of cathode casing. 2 cl, 7 dwg
