RESISTANCE OF ANODE IRON CURRENT SUPPLIES IN MAGNESIUM ELECTROLYZER WITH BOTTOM ANODE LEAD-IN

摘要

Relationship between resistance of anode iron current supplies and electrolyte temperature was determined on diaphragm-free electrolyzers with bottom anode lead-in. It was found out that rise of electrolyte temperature leads to increase of corrosion speed of iron current supplies and cathodes, as well current output decreases. Destruction mechanism of current supplies is described, and voltage enlargement in 《iron-graphite》 contact was determined during the campaign. The results of testing of electrolyzers showed that rise of iron content in waterless carnallite by 0,01 percent is followed with decrease of current output by 2,3 percent.
