500 kA铝电解槽磁场数值模拟及测试分析

Numerical simulation and test analysis of magnetic field in 500 kA aluminum electrolyzer

利用SolidWorks三维建模及COMSOL三维仿真模拟软件,对500 kA铝电解槽进行数值模拟.对某厂家500 kA铝电解槽进行磁场测试,测试结果与模拟结果吻合较好.得出500 kA铝电解槽的磁度分布,并对500 kA铝电解槽进行磁场优化,通过增加立柱母线和槽周母线到铝电解槽的距离降低立柱母线与槽周母线对铝液层的影响.优化使得铝液层在Z轴方向上磁场分布趋于均匀稳定.为改善生产工艺技术条件提供了技术支持.

Using 3D modeling of SolidWorks and 3D simulation software of COMSOL,the numerical simulation of 500 kA aluminum electrolyzer was carried out.A magnetic field test on 500 kA aluminum electrolyzer of a manufacturer is carried,and the test results are in good agreement with the simulation results.The magnetic field distribution of 500 kA aluminum electrolyzer was obtained and optimized,the influences of the column bus bar and groove bus bar on the molten aluminum layer are reduced by increasing the distance between the column bus bar and aluminum electrolyzer as well as the distance between the groove bus bar and aluminum electrolyzer.After the optimization,the magnetic field distribution of the molten aluminum layer tends to be uniform and stable along the Z-axis direction.The simulation and test provide technical support for improving the technical conditions of production process.
