摘 要: 运用大型有限元分析软件ANSYS中附带的APDL模块解决铝电解槽热非线性和炉帮形状的循环计算问题，充分考虑电解质发生相变时产生的潜热， 建立了热电场数学模型， 开发了准三维热电耦合模型。 选择普通炭块和碳化硅作为侧部保温材料两种情况， 对我国300kA侧部五点进电预焙铝电解槽进行了热电耦合分析，绘出了热场等温线图。 结果表明， 300kA侧部五点进电预焙电解槽的阴极和侧部炭块的设计是合理的。

Abstract: By using ANSYS APDL, the non-linear behaviors in aluminum reduction cell were considered and the profile of bath freeze was computed. Considering the phase change problems, the thermo-electric mathematical models and 2D+ thermo-electric models were built up. For the cases of common carbon and SiC, the thermo-electric coupled filed of 300kA prebaked aluminum reduction cell was computed. The results indicate that the design of cathode and side of 300kA prebaked aluminum reduction cell is reasonable.
