Comprehensive Evaluation Method for the Aluminum Electrolytic Cells Performance based on the Information Entropy
Through the analysis of electromagnetic force,one of the most important factors in estimating the aluminum electrolytic cells stability and was caculated based on the information entropy.Considering energy consumption,a comprehensive evaluation method of stabilization and energy consumption of the aluminum electrolytic cells was put forward and applied on the study about the electromagnetic field under the condition of different polar distances of the 320 kA aluminum electrolytic cells.The result showed that the index can effectively and comprehensively evaluate cells stability and energy consumption,and revealed the influence relationship between the polar distances and aluminum electrolytic cell stability,the current efficiency and slot voltage,and a polar distances configuration which keeped 320 kA aluminum cell efficiently operation was obtained.
