摘　　要：利用SOLIDWORKS建模软件及COMSOL仿真软件对某厂家350 kA铝电解槽进行电场磁场模拟,对比传统普通阳极炭块电解槽和不同石墨化度阳极炭块电解槽电场磁场的差异。笔者根据不同石墨化度炭块理化性质的不同,探索不同石墨化度阳极炭块对电解槽电场磁场的影响差异,发现阳极炭块石墨化处理可降低电解槽整体电压降,降低铝液中水平电流密度,减小垂直于铝液方向的磁通密度。基于此,认为阳极炭块的最优石墨化度为10%。By means of the SOLIDWORKS modeling software and COMSOL simulation software,the electric field and magnetic field of a 350 kA aluminum electrolytic cell of a factory were simulated,and the differences of electric field and magnetic field between traditional ordinary anode carbon block electrolytic cells and electrolytic cells with anode carbon blocks of different graphitization degrees were compared.According to the different physical and chemical properties of carbon blocks of different graphitization degrees,the influence of anode carbon blocks with different graphitization degrees on the electric field and magnetic field of electrolytic cell is explored.It is found that graphitization treatment of anode carbon blocks can reduce the overall voltage drop of electrolytic cell,the horizontal current density in aluminum liquid and the magnetic flux density perpendicular to the direction of aluminum liquid as well.Based on this,it is considered that the optimal graphitization degree of anode carbon block is 10%.
