| Abstract Scope |
Anode change is a key production process in aluminum electrolysis and causes zone anode current fluctuations in reducing cells. When the anode in the zone changes, the zone current decreases significantly. As the new anode heats up and participates in the electrochemical reaction, the current gradually recovers. The recovery modes for the anode swap zone current are complex and can be broadly divided into three modes: linear, plateau, and surge. The plateau mode occurs most frequently and may be due to the slow dissolution of the solidified electrolyte on the surface of the new anode. The surge pattern is caused by a change in the anode in the adjacent area during the recovery period, which results in a current surge of approximately 4.5 kA. These features of current recovery in the anode replacement zone can be used to optimize alumina feed control during electrolysis production. |
