摘　　要：普通预焙槽电解过程会形成一定厚度的槽帮,它的形成对于铝电解生产的正常进行有着十分重要的作用。本文用有限元方法建立了一个200kA预焙槽的二维电热模型,通过循环迭代,模拟出了其槽膛内形。计算结果与现场测试结果比较表明,二者吻合较好。A layer of certain thickness will be formed on the side wall of cell during aluminum electrolysis process.It is of much importance to normal operation of electrolytic cell.A 2D thermoelectric model of a 200 kA prebaked cell is set up by using finite element code.Then,tank hearth profile will be simulated through iterative loop.It is found that the result calculated is good agreement with that measured in situ.
