Keywords: Aluminium electrolysis, excess AlF3, control, bath temperature

Abstract: In this paper we investigate from a theoretical point of view the impact of varying bath temperature, excess AlF3 and alumina concentration on cell resistance and cell control. The results are interpreted using knowledge of the behavior of general resistance and anode beam controllers to study the influence on the anode cathode distance. This again leads to the proposal of a new control strategy for bath temperature and excess AlF3. The theoretical results obtained are supported using real data.
