摘　　要：应用等效电阻网络法与有限元相结合的方法,对侧部四点进电铝电解槽电流场进行了数值计算。计算结果表明,铝电解槽铝液中存在着由进电端指向出电端的水平电流,铝液电流密度四个角部最大,达到22214A/m2,总体上铝电解槽电流分布较为对称。应用此方法,不仅可应用于传统电解槽的优化设计,也为新型导流型电解槽的开发打下了良好的技术基础。Equivalent resistance method（ERM） and finite element method（FEM） is adopted in this paper to calculate current held in aluminum reduction cells of four side anode risers. The calculated results indicate that anode current in A side is large than of B side but cathode in A side is less than of B side, these indicate that horizontal current from A side to B side exists in aluminum reduction cells, Current density in metal pad in four corners is laxgest then other place, up to 22214 A/m2. As a whole, current distribution in alumium reduction cells is quite symmetrical,, So Equivalent resistance method and finite element method are not only applied to optimization design of traditional reduction cells, but also to establish better technology basis to development of new drained aluminum reduction cells,
