摘 要: 以商業(yè)軟件ANSYS為開發(fā)平臺， 采取標(biāo)量電位法和雙標(biāo)量磁位法相結(jié)合的方法開發(fā)了鋁電解槽電場與磁場計算模塊，并應(yīng)用到154kA鋁電解槽磁場計算。 磁場計算結(jié)果表明： 水平磁場基本上形成一個順時針的漩渦， 而垂直磁場呈現(xiàn)較好的反對稱關(guān)系; |Bx|max、 |By|max和|Bz|max的計算值與測試值誤差分別為0.7%、 8.8%和6.7%； 各個測點的磁感應(yīng)強(qiáng)度分量Bx、 By和Bz計算值與測試值絕對平均誤差分別為14.8%、 7.8%和14.9%。 計算值與測試值比較接近， 表明該方法可以滿足鋁電解槽母線設(shè)計時的磁場仿真計算的要求。

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 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.
