The Road to Optimization of 500 kA Aluminum Electrolysis Cell Process Technology
The world's first 500 kA electrolytic aluminum production line of Liancheng Branch has been affected by factors such as large tank size,high current density,and raw materials.Since its commissioning,except for no fundamental improvement in the main indicators of electricity consumption,the consumption of materials such as alumina and anode wool has met the standard,and the tank life has reached the expected level.Based on this,members of the process technology team conducted analysis and research on the design of the magnetic field and flow field of the electrolytic cell,furnace size and busbar configuration,thermal balance and heat dissipation distribution,electrolyte composition control,material balance and self-control system,and continuously explored and optimized to ensure the smooth operation of the system.
