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 154kA 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.
