以某厂SY300型预焙槽为基础简化模型,利用solidworks软件建立铝电解槽三维物理模型。在使用部分假设条件、合理理想分割场域、多场共享模型信息和结果的前提下,运用COMSOL Multiphysics有限元软件和Matlab软件分别建立了物理模型的电场,磁场,流场及其耦合场的计算模块。在COMSOL平台上,求解更换阳极时电解槽的电场和磁场,对电流密度和磁场分布进行仿真、分析和讨论。针对不同槽膛形状给出了相应的铝液流场。研究表明,水平电流对磁流体运动有显著的影响,铝液的形态基本呈对称状态。
Based on the SY300 prebake cell of a certain plant, the model was simplified and solidworks software was used to establish the 3D physical model of the aluminum reduction cell. Under the assumption of some assumptions, reasonable and ideal segmentation of the field, and the sharing of model information and results in multiple fields, the calculation of the electric field, the magnetic field, the flow field and the coupling field of the physical model are established by using COMSOL Multiphysics finite element software and Matlab software respectively Module. On the COMSOL platform, the electric and magnetic fields of the electrolyzer during anode replacement were solved, and the current density and magnetic field distribution were simulated, analyzed and discussed. Corresponding aluminum liquid flow field is given for different groove shapes. The research shows that the horizontal current has a significant influence on the magnetic fluid movement, and the shape of the aluminum liquid is basically symmetrical.
