摘　　要：主要介绍了抗氧化防腐涂料在400 kA系列预焙阳极铝电解槽预焙阳极及钢爪表面上涂刷(或喷涂)应用,分析、验证抗氧化防腐涂料对预焙阳极及钢爪的抗氧化防腐效果。结果表明,阳极抗氧化防腐涂料具备良好的抗氧化性,刷涂抗氧化防腐涂料的阳极,无阳极氧化和阳极钢爪被氧化和侵蚀现象,可延长阳极换极周期至少1天以上。This paper mainly introduces the application of anti-oxidation and anti-corrosion coating on the surface of pre baked anode and steel claw of 400 kA series pre baked anode aluminum electrolytic cell, analyzes and verifies the anti-oxidation and anti-corrosion effect of anti-oxidation and anti-corrosion coating on pre baked anode and steel claw. The results show that the anode anti-oxidation coating has good anti-oxidation property, and the anode coated with anti-oxidation coating has no anodizing and the anode steel claw is oxidized and eroded, which can prolong the anode pole changing period for at least one day.
