330 kA铝电解槽异形阴极碳块对水平电流的影响

采用有限元仿真计算，对330 kA铝电解槽进行传统阴极碳块结构和异形阴极碳块结构的电场进行仿真模拟，主要对铝液中水平电流分布进行分析。研究发现，异形阴极碳块结构相对于传统阴极碳块结构能够在影响压降较小的前提下降低水平电流密度。模拟结果表明，在异形阴极碳块表面凸起中增加隔断并改变凸起角度，对降低铝液中水平电流效果明显，能够降低铝液中最大水平电流密度27.8%，平均水平电流密度34.3%，有效提升了铝电解槽电流效率。

Effect of Shaped Cathode Carbon Blocks on Horizontal Current 330 kA Aluminum Electrolytic Cell

Finite element simulation calculations were employed to simulate the electric field of a 330 kA aluminum electrolytic cell with both traditional and shaped cathode carbon block structures. The main focus was on analyzing the horizontal current distribution in the molten aluminum. The study reveals that compared to the traditional structure, the shaped cathode carbon block structure can reduce the horizontal current density with a minimal impact on the voltage drop. The simulation results indicate that adding partitions on the surface protrusions of the shaped cathode carbon block and altering the protrusion angles has an obvious effect on reducing the horizontal current in liquid aluminum, which can reduce the maximum horizontal current density of aluminum melt by 27.8% and the average horizontal current density by 34.3%, and effectively improve the current efficiency of aluminum electrolytic cell.
