摘  要:针对8 kA稀土电解槽石墨阳极有效使用时间低于预期、残极率高及更换阳极后炉况波动大的情况,采取了调整石墨阳极尺寸、优化阳极布局、增加阳极数目的措施。生产实践表明:优化阳极布局结构后的8 kA稀土电解槽阳极残极率下降9.3百分点,阳极单耗降低了6.5%,电流效率提升0.8百分点,电解槽在更换阳极后炉况的稳定性及部分电解生产技术指标都得到了提升。In order to address issues such as the shorter effective service life of graphite anodes than expected,high residual anode rates,and significant instability in furnace conditions after anode replacement in the current 8kA rare earth electrolyzer,measures were implemented to adjust the dimensions of the graphite anodes,optimize the anode layout,and increase the number of anodes.Production practices have demonstrated that after optimizing the anode layout structure,the residual anode rate of the 8 kA rare earth electrolyzer decreased by 9.3 percentage points,the anode consumption per unit reduced 6.5%,and the current efficiency increased by 0.8 percentage points.Furthermore,the stability of the electrolyzer's conditions after anode replacement and several electrolysis production technical indicators have been improved.
