| Abstract Scope |
Based on the research on the material balance and energy balance of the electrolysis cell, and combined with the simulation analysis of the key technological parameters of the historical operation of the 500 kA electrolysis cell with graphitized cathode ,the influences of aluminum electrolysis temperature, molecular ratio,aluminum level and average voltage on the DC power consumption of aluminum electrolysis were described, and the key technological parameters of aluminum electrolysis were coupled. The range of the optimal DC power consumption of the key technical parameters of aluminum electrolysis was found and combined into a control model of the key technical parameters of the key process. The optimal control model was used to guide the production practice. Under the guidance of the control model,the current efficiency of aluminum electrolysis increased,the DC power consumption decreased significantly,and god economic results were achieved. |
