Evaluation and Application of Energy Efficiency in Electrolytic Aluminum Industry

As a high energy-consuming industry, electrolytic aluminum industry consumes too much social resources, which needs to further improve its energy efficiency. This paper analyzes the different views of evaluating the energy efficiency level of electrolytic aluminum industry, and presents it in the form of constructing energy efficiency evaluation index system. Through the calculation of the index and the determination of weight, the level of energy efficiency in the typical scene of electrolytic aluminum industry is evaluated. Finally, an example is given to verify the effectiveness of the evaluation method. This study provides guidance for the improvement of energy efficiency of electrolytic aluminum, and lays the foundation for the implementation of the follow-up energy efficiency improvement scheme.
