| Abstract: |
| FEM of aluminum electrolytic cell electric field under abnormal condition was built based on ANSYS commercial software platform applying 420 kA large-scale prebaked anode aluminum reduction cell as object. The effects of sludge and anode exchange on electric field in running process were calculated and analyzed. The results show that large-area sludge formation changes the original steel bar current distribution characteristics obviously, but dispersive and small precipitation has little influence on current distribution of steel bar. Electric field of electrolyte layer, average current density of liquid aluminum layer, and steel bar current change sharply with change of anode change positions. This research can be fundamental for precipitation diagnostic analysis and anode exchange system optimization. |
