通过对槽内磁场、电流场的分析和研究,提出一种静流式铝电解槽的概念,采用阴极垂直出电的方式代替目前的水平出电方式,从而大幅度降低铝液层中的水平电流,大幅度削弱电磁力对槽内熔体的影响,进而减小铝液的流动和波动,将电磁影响削弱到最低程度以实现熔体界面高稳定性,并依此原理设计开发新型高效节能型铝电解试验槽.同时对母线配置进行设计,在最优化母线配置下,磁场数值仿真计算结果表明,该电解槽垂直磁场最大值为0.896 3 mT,平均值为0.360 2 mT,远低于同规格普通电解槽的垂直磁场,从而可获得电解槽超稳定运行条件,为大幅度降低极距,实现大幅度节能创造条件.%The concept of stationary stream pattern aluminum reduction cell was presented after analyzing the magnetic field and current flows of aluminum reduction cells. With this kind of innovative design, the electricity flows out of the cell in a vertical path instead of current horizontal path, so the current flow intensity in aluminum melt can be reduced sharply, and the effect of electromagnetic force on the melt is weakened. Furthermore, the flow and fluctuation of the aluminum melt becomes lower, and the effect of electromagnetic force decreases to the minimum level. Under the above principle, a novel kind of high efficient aluminum reduction test cell was designed. With optimal busbar designing method, the simulation results show that the maximum vertical magnetic field strength is only 0.896 3 mT, and the mean value is 0.360 2 mT, which are far below the values of ordinary cells with the same scale. Thus, the cell can perform steady with much lower polar distance, and the goal of substantially energy-saving target would be achieved.
