Abstract

Effective monitoring and precise control of electrolyte and liquidus temperatures (which together give superheat levels) are imperative for optimising the performance, extending the lifespan, and improving the current efficiency of aluminium smelter cells. During periods of intensive and frequent power modulation, where the power input to the cell is altered, maintaining a perfect mass and thermal equilibrium becomes increasingly challenging. As a result, both bath temperature and superheat will invariably fluctuate. This paper presents a study of a power modulation event, as well as encouraging results on the use of a comprehensive dynamic model, which integrates mass and thermal balances, for the continuous prediction of the bulk electrolyte and liquidus temperatures, ledge thickness, and bath compositions. This paper is working towards addressing the absence of continuous thermal measurements suitable for real-time thermal monitoring and control, especially under complex conditions introduced by power modulation.
