Abstract Scope The bath temperature of a Hall-Héroult cell is an important process variable which affects the aluminium smelting process conditions including the superheat, the alumina dissolution and the energy consumption. However, it cannot be easily measured continuously for real-time monitoring. This paper presents a thermal model of a Hall-Héroult cell and its top chamber, and proposes the use of an extended Kalman filter as a model-based state observer to estimate the average bath temperature continuously in real-time under different process operation scenarios from the variables including the duct gas temperature and velocity. The proposed approach helps improve online operation of aluminium smelting cells by maintaining appropriate thermal balance including superheat and aluminium fluoride level.
