Abstract
This paper analyzes the way to reduce the energy consumption of aluminum electrolytic cell,and comprehensive-ly considers the various factors affecting the energy consumption of aluminum electrolysis,and carries out the process opti-mization test on the 500 kA aluminum electrolytic cell.Through the control system parameter qualification setting,the opti-mization of the process technical conditions such as Al2O3 concentration,aluminum level,molecular ratio and superheat,the control system parameters are highly matched with the technical conditions of aluminum electrolytic cell.The current ef-ficiency of aluminum electrolytic cell is improved,the average voltage is reduced,and the comprehensive AC power con-sumption of aluminum liquid is greatly reduced.
