IN DEPTH ANALYSIS OF ENERGY-SAVING AND CURRENT EFFICIENCY IMPROVEMENT OF ALUMINUM REDUCTION CELLS

In view of the existing aluminum overcapacity and lower aluminum price in China, many companies have taken measures to reduce production costs and energy consumption. However, there has been no standardized theory or method defined to date. This paper addresses these issues by highlighting the evident impacts of energy-saving and current efficiency improvements in aluminum reduction cells, achieved through new thermal insulation pot lining designs, optimal cathode structure applications, and reductions of horizontal current devices. The research combines the application of new lining materials with relevant process parameters, utilizing finite element software ANSYS® and thermal field simulation software, alongside actual production data, as its calculation methodology. The results demonstrate that this integrated approach, which combines design, simulation, and experimental practices, is effective and feasible in achieving lower energy consumption, cost reduction, and higher profit margins. Specifically, the implementation of these methods has proven to significantly reduce energy consumption in a plant in China, resulting in substantial operational cost savings. This approach is key to elevating Chinese aluminum reduction technology to a globally advanced level amid ongoing energy crises.
