Description
Summary:In electrolytic aluminum production, anode rods, industrial tools, and gas purification equipment corrode intensely. A high corrosion rate of the tools and equipment in cryolite-alumina melts is found. To decrease the corrosion destruction of operating equipment and anode rods made from ferrous metals, it is suggested to deposit composite chromium coatings. Purification of electrolytic gases from sulfur dioxide is possible by the acidic scheme with obtainment of sulfurous acid. However, this is accompanied by intense corrosion of equipment made from ferrous metals. The possibility of applying corrosion inhibitors, specifically oxazolidines, for protection of gas purification equipment made from steel CT3 that exists in aluminum plants is considered.
