【摘要】 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。更多还原

【Abstract】 The SY300 Prebake cell of some factory as a basic simplified model, the solidworks software was used to build a three-dimensional physical model of aluminum reduction cell. In the use of some assumptions, reasonable ideal field segmentation and under the premise of sharing model information and results, the physical model of electric field, magnetic field, flow field and its calculation module of coupling field were established respectively by using the the finite element software Comsol and Matlab Multiphysics software. On Comsol platform, electric, magnetic field of aluminum electrolytic cell were solved when replacing the anode, and current density and magnetic field distribution were simulated, analyzed and discussed. According to different groove chamber shape, aluminum liquid flow field were given, too. Study shows that the horizontal movement has significant influence on magnetic current, liquid aluminum forms the basic symmetry state.更多还原
