摘　　要：提出了两种5 kA级惰性阳极铝电解槽结构,使用有限元仿真方法计算了不同槽型电解槽在分别采用普通阴极、石墨化阴极下的电热场分布情况。计算结果表明:不同槽型电解槽在初始条件下热量不平衡,但在强化电流、增加极距、加强保温后,均能实现热平衡;采用石墨化阴极需要输入更多的热量才能实现热平衡,但能够使阴极底部等温线分布更合理;在同样达到热平衡时,槽型2结构略优于槽型1。Two cell structures of 5kA scale inert-anode aluminum reduction cell were put forward and the thermoelectric field was calculated using finite element method with common cathodes and graphitized cathodes,respectively.The results indicate that the heat is not balanced for both cell structures under initial conditions but it can be balanced by intensifying current,the anode-cathode distance and heat preservation.The cell with graphitized cathodes needs more energy to achieve heat balance but it can assure more reasonable temperature distribution in the cathodes.The cell structure 2 is a little better than the cell structure 1 considering the thermoelectric field distribution only.
