Abstract

Two versions are considered for modernizing the construction of a type S-8BM Soderberg electrolyzer cathode unit, developed by the department of new technologies of the Engineering-Technological Center of OOO Rus-Inzhiniring. Industrial tests show that both structures make it possible to lower the metal level from 50 to 25 cm and to increase the current strength from 174 to 185 kA without worsening the technical and economic indices of electrolyzer operation. The anticipated risk of anode overheating connected with descent of the anode deeper into the cathode shaft, and also creation and support of an acceptable shape of the work space as a result of lowering the metal level and increasing the current strength during the operating period does not develop.
