Recently, the major project of Zhengzhou Collaborative Innovation “The Development of Energy Flow Optimization and Intelligent Control System of Aluminum Cell”, jointly undertaken by Zhengzhou University, Zhengzhou Light Metal Technology Co., Ltd, Henan Zhongfu Industrial Co., Ltd, etc., has completed the basic experimental research and industrial system development and integration, and the first set of system has been formally put into industrial operation in Zhongfu Aluminum Industry Co., Ltd.

At the launching ceremony, Professor Liang Xuemin from School of Materials Science and Engineering of Zhengzhou University, who is in charge of the project, introduces the progress of the project and the preliminary research results obtained so far. Subsequently, the first set of energy flow optimization and intelligent control system of 400kA electrolytic cell (HORRS system) starts smoothly.

In the future, the project team will carry out further research to obtain the optimal thermal characteristics of the electrolytic cell through energy flow optimization, explore the limit optimization process of the operation of the electrolytic cell, and further tap the potential of “input terminal energy” of aluminum electrolysis. At the same time, the new concept of “output terminal energy saving” in aluminum electrolysis is established. Based on the successful implementation of the interconnection with the urban heat network, research is carried out step by step and new technologies and complete sets of industrial systems are developed to expand the application field of “output terminal energy saving” of electrolytic aluminum to interconnect with large industrial user systems such as industrial heat network, in order to achieve the overall goal of 8%~10% energy saving for electrolytic aluminum.

The successful development and application of this technology will open up a new energy saving approach for China’s aluminum electrolysis industry, and provide a strong technical support for China’s aluminum industry to implement the national goals of “peakingcarbon dioxide emissions” and “carbon neutral”.
