| 摘 要： | 使用有限元法建立了铝电解槽三维静电磁场耦合计算模型。该模型考虑了槽内导体、母线系统、铁磁材料及空气漏磁等因素对磁场解析的影响; 采用六面体单元对模型进行网格划分; 先求解得到电场结果, 再在该结果基础上采用常规标量法(GSP)分三步对磁场进行求解。以350 kA预焙阳极铝电解槽为例, 分别计算了同厂房中不同相邻槽数和不同的相邻厂房对磁场的影响情况, 发现上下游各选用3台相邻槽和两侧都有相邻厂房的设计较为合理, 并用在此条件下建立的模型计算并优化了该电解槽系列的电磁场分布情况, 得出垂直磁场范围在-2.87×10-3 T至2.15×10-3 T之间, 并与工厂实际测量得到的结果进行对比, 数值接近, 证明了模型和结果的合理性。

| Abstract: | Three-dimensional steady models to caculate coupling electromagnetic field in aluminum reduction cells were developed by finite element method.Effects caused by inside induced current,busbar system around,ferromagnetic shell as well as air were considered.The model was meshed by hexahedrous element.First,the electric current density was calculated,then the results of magnetic field were solved by General Scalar Potential(GSP) with three steps.Taking 350 kA prebaked aluminum reduction cells for example,the e... |
