摘　　要：本文基于实际生产中端头槽电流效率低、稳定性差的情况进行研究分析,从设计角度分析了端头槽与普通槽熔体区磁场存在较大差异的原因。本文探讨了仿真模型中上、下游电解槽数量对计算槽磁场的影响,在此基础上分析端头进出电槽磁场与普通槽相比恶化的表现及原因。同时,通过现场经验总结和大量的模拟计算,针对端头槽提出优化设计方案。模拟计算结果表明,优化后的端头槽磁场分布得到明显改善,对于电解系列端头槽的安全、稳定生产具有重要意义。This paper conducts research and analysis based on the low current efficiency and poor stability of the end aluminum reduction pot in actual production,and analyzes the reasons for the significant differences in the magnetic field in the melt zone between the end aluminum reduction pot and the ordinary aluminum reduction pot from a design perspective.This paper explores the influence of the number of upstream and downstream aluminum reduction pot in the simulation model on the calculation of the cell magnetic field.Based on which,it analyzes the performance and reasons for the deterioration of the magnetic field in and out of the aluminum reduction pot compared to ordinary aluminum reduction pots.Meanwhile,through on-site experience summarization and extensive simulation calculations,an optimized design plan is proposed for the end aluminum reduction pot.The simulation calculation results show that the optimized magnetic field distribution of the end aluminum reduction pot has been significantly improved,which is of great significance for the safe and stable production of the end aluminum reduction pots in the potline.
