摘    要:以商业软件ANSYS为开发平台, 采取标量电位法和双标量磁位法相结合的方法开发了铝电解槽电场与磁场计算模块,并应用到154kA铝电解槽磁场计算。 磁场计算结果表明: 水平磁场基本上形成一个顺时针的漩涡, 而垂直磁场呈现较好的反对称关系; |Bx|max、 |By|max和|Bz|max的计算值与测试值误差分别为0.7%、 8.8%和6.7%; 各个测点的磁感应强度分量Bx、 By和Bz计算值与测试值绝对平均误差分别为14.8%、 7.8%和14.9%。 计算值与测试值比较接近, 表明该方法可以满足铝电解槽母线设计时的磁场仿真计算的要求。

Abstract: On the basis of commercial software ANSYS, the scalar voltage potential method and two scalar magnetic potentials method were used to establish a calculating module of magnetic field and electric field in aluminum reduction cells. The calculated results indicate that the horizontal magnetic filed forms a clockwise swirl and the vertical magnetic field presents the relation of reversed symmetry in 154kA prebaked anode aluminum reduction cells. By the comparison between calculated results and measured results, it is shown that the errors of |Bx|max, |By|max and |Bz|max are less than 10% and the average errors of Bx, By and Bz in every point are less than 15%. These indicate that the results calculated by applying the scalar voltage method and two scalar magnetic potentials method are comparatively precise and meet the need of designing aluminum reduction cells bus-bar.
