摘　　要：借助ANSYS有限元分析软件,建立了铝电解槽1/4槽有限元解析模型,对其电、热场进行耦合计算,并以某厂156kA预焙阳极铝电解槽为研究对象,根据实测的电解槽运行数据对模型进行了检验,结果表明:本文所建立的1/4槽有限元解析模型的计算结果与实测值吻合较好(电压降偏差在30mV以内,炉帮特征尺寸偏差在2cm以内,槽壳表面温度偏差10℃以内),能较真实地反应铝电解槽内的电、热场的三维分布状况,可为铝电解槽的优化设计提供准确、快速且经济、可靠的研究手段。The finite element model of the quarter of aluminum reduction cell is built and the thermal- electric field of the cell is computed according to the finite element analysis software ANsYS, A 156KA baked anode aluminum reduction cell is analyzed and reseazched by using the model. The results show that the simulation results coincide with the tested data （the error of the Voltage drop is less than 30mV, and the elgenvalue of freeze less than 2cm, the temperature on shell surfaces less than 10℃ ）, and thermal- electric field distribution of the cell is truly reflected. Therefore provide good methods for designed and optimizing of aluminum reduction cells.
