摘　　要：以3 kA稀土电解槽为研究对象,采用有限元分析软件AYSYS WORKBENCH建立电解槽的数学模型,分析几种不同的常用阳极炭块材料对稀土电解槽的电场影响。结果表明,采用半石墨质,半石墨化和石墨化三种阳极炭块,其熔体电压分别是5.8575 V、5.7699 V、5.6791 V。综合计算表明,使用石墨化阳极材料可以降低成本,从而获得良好的经济效益。In this paper a mathematic model of 3KA rare earth electrolysis cell was developed by using the finite-element analysis software ANSYS WORKBENCH to analyze the impact of several different common anode carbon block material on the electric filed of rare earth electrolysis cell. Calculation results show that melt voltage of semi-graphitic,semi-graphitized and graphitized anode carbon block are 5. 8575 V,5. 7699 V,5. 6791 V. Through the comprehensive consolidation,choosing graphitized electrode can reduce costs and improve the overall economic benefits of rare earth industry.
