为探讨400 kA铝电解槽的差异和发展趋势，对4种具有代表性的电解槽进行了深入分析。利用ANSYS软件中的数值模拟方法，首先对结构参数进行比较，然后建立三维电磁流场模型，并采用有限元法进行求解。通过结构对比发现，两种电池的电池本体相似，但电流路径和母线分配比不同。A侧电流的70%~ 80%作为磁场补偿电流流经两端。数值模拟结果表明，磁场分布不同，但均满足磁流体动力学稳定性，流态均为适当速度的双涡或多涡。对比表明，所研制的400 kA电池均能满足物理场要求，商业应用也验证了400 kA电池已成为技术成熟、世界领先的产品。
To investigate the differences and the development trends of the 400 kA aluminum reduction cell, four representative cells were deeply analyzed. By using numerical simulation methods in ANSYS software, the structure parameters were firstly compared, and then three-dimensional models of electric-magnetic-flow field were built and solved with finite element method (FEM). The comparison of the structures reveals that the cell bodies are similar while the current flow path and distribution ratio of bus bars are different. It appears that most of the current (70%–80%) in side A are used as the magnetic field compensation current and flow through two ends. The numerical simulation results indicate that the distributions of magnetic fields are different but all satisfy with the magnetohydrodynamics (MHD) stabilization, and the flow patterns are all two or multi vortexes with appropriate velocities. The comparison shows that all studied cells can satisfy with the physical field requirement, and the commercial applications also verify that the 400 kA cells have become the product of the mature and world’s leading technology.
