The authors of this paper using the thermo-electric field simulation software secondary development based on ANSYS studied the horizontal current distribution in liquid aluminum pad of two cases, namely the cathode and anode configuration adopting “correspondence” and “non-correspondence”. The results showed that the effect of reducing horizontal current is not obvious when anode and cathode using “correspondence” configuration, especially during the actual production cannot eliminate the uneven distribution of anode current, and also can not eliminate the horizontal current caused by anode change. The structure of modern reduction cell determined the horizontal current in the liquid aluminum pad mainly derived from cell width direction, namely the direction of current in and out. Therefore, the reducing of horizontal current should also be more considerate on the cell width direction. The number of cathode should not be previously determined during the bus configuration around the cell.
