摘　　要：氯化物熔盐电解槽内部磁场的稳定对电流效率的提升非常重要。以50 kA氯化物熔盐电解槽为研究对象,运用有限元软件COMSOL建立电解槽三维电磁场模型,模拟了50 kA电解槽不同平面x、y、z三个方向的磁场强度和电磁力分布特点,重点研究工艺参数对磁场强度和电磁力分布的影响。结果表明,电流增加,每个平面的磁场强度和电磁力均增加,且增幅相同;降低极距、增加电解质液面高度、增加阳极半径均会使磁场强度最大值和电磁力最大值增加。The stability of magnetic field inside the chloride molten salt electrolysis cell is very important for the improvement of current efficiency.Applying 50 kA chloride molten salt electrolysis cell as research object,and the finite element software COMSOL was used to establish a three-dimensional electromagnetic field model of the electrolysis cell,which simulated the magnetic field strength and electromagnetic force distribution characteristics of the 50 kA electrolysis cell in different planes x,y and z,focusing on influence of process parameters on magnetic field strength and electromagnetic force distribution.The results show that as the current intensity increases,the magnetic field strength and electromagnetic force of each plane increase,and the increase range is the same.Reducing the polar distance,increasing the height of electrolyte level,and increasing the anode radius will increase the maximum magnetic field strength and electromagnetic force.
