摘　　要：近年来石墨化阴极炭块凭借其优异的性能被电解铝行业所青睐。但部分企业只将阴极及其他部分内衬材质做了改变,磁场及母线配置并未调整,导致电解槽能量平衡不匹配,出现电解槽偏冷、伸腿肥大等现象,影响电解槽的正常生产。本文采取对全石墨阴极电解槽进行钢棒保温这一措施,有效减少电解槽散热,通过对钢棒保温前后的温度、效应系数、以及电压差值进行对比分析,有效证明该措施有效,最终达到引导电解槽能量趋于平衡的目的。In recent years,the graphitized cathode carbon block has been favored by electrolytic aluminum industry because of its excellent properties.However,some enterprises only changed the lining material of the cathode and other parts,and the magnetic field and bus configuration were not adjusted,thus resulting in a mismatch in the energy balance of the electrolytic cell,as well as the phenomenon of the electrolytic cell being cold and extending the ledge,which seriously affected the normal production of the electrolytic cell.In this paper,the measure of steel bar insulation for the fully-graphitized cathode electrolytic cell is adopted to effectively reduce the heat dissipation of the electrolytic cell.Through comparative analysis of the temperature,effect coefficient and voltage difference before and after the steel bar insulation,it is effectively proved that the measure is effective,thus finally achieving the purpose of energy balance of the electrolytic cell.
