Finite element simulation method was used to simulate the electric field of 400 kA aluminum electrolytic cell under the traditional cathode steel bar structure and the special-shaped cathode steel bar structure, which mainly included the cathode voltage drop and the level current of aluminum liquid. An improved structure of cathode steel bar was proposed by analyzing the abnormal structure of the cathode steel bar. The cathode steel bar has the characteristics of bulge and extension. The result shows that the improved cathode steel bar can further reduce the voltage and level current of aluminum electrolytic cell, thus improving the current efficiency of electrolytic cell, reducing the energy consumption of a single cell by about 33.6 kW•h, and improving the stability of electrolytic aluminum.
