Abstract

The practice of aluminum plants for creation and improvement of an anode mass cover is reviewed. Aluminum plants operating low-power electrolyzers use alumina as a cover material, exhibiting low thermal conductivity, but good gas permeability. Operation of more powerful electrolyzers requires effective anode protection from oxidation, a reduction in carbon dioxide discharge, stabilization of the bath thermal balance with a high current, and optimization of heat loss upwards through a cover. A contemporary cover consists of a mixture of crushed electrolyte and alumina in almost equal proportions, and it is an electrolyzer subsystem having a marked effect on technical and economic indices.
