Research of Aluminum Reduction Cell Thermal Balanced Intelligent Control System

Abstract:

This paper proposes an intelligence control system of heat balance for aluminum reduction cell and reviews in each period the control technique of aluminum electrolysis at home and abroad. Mutual coupled relations of physical fields such as electric field, magnetic field, flow distribution, thermal field, stress field, concentration field in aluminum reduction cell are analyzed simply. In this system automatic control of furnace temperature and liquidus temperature in aluminum electrolyte are detected in real-time accurately. This control system can reduce the superheat of aluminum reduction cell in a certain range, and reduce production cost of per ton of primary aluminum on maximal degree. Thus, energy consumption and waste is decreased and heat balance in aluminum electrolysis is realized, efficient operations are certified in the product of aluminum electrolysis.
