Informative Features Selection for Building an Optimization Model of the Aluminum Electrolytic Cell Thermal Regime
Abstract
Mathematical modeling is the main tool for optimizing the operation of aluminum electrolytic cells. It
helps to get answers to important questions to developers of complex systems in the aluminum
industry. It contributes to the intensification and improvement of these systems development in the
quality with minimal resources and time. One of the main parameters characterizing the process of
aluminum electrolysis is the current efficiency, an output indicator that evaluates the efficiency of the
aluminum electrolytic cells. The paper proposes to use modeling regression equations for automatic
control of the electrolyte temperature according to the statistical parameters of voltage fluctuations.
It helps to control the technological process of electrolysis with correction for the melt temperature
quickly. The authors propose a mathematical model of the thermal regime of an aluminum electrolytic cell based on an estimation of the relationship between the melt temperature and the main indicators of the electrolysis process (melt temperature and composition, concentration of dissolved alumina, cryolite ratio, anode-cathode-distance (ACD) and voltage fluctuation parameters.
