Aluminum Reduction OverviewThis article describes the application of a mathematical dynamic model of an aluminum smelter cell. The model-based programs are used to train personnel. Planned changes in process parameters are fi rst calculated to choose the best practice, and in this paper, the authors give examples of such calculations illustrated by graphs and diagrams. A description is also offered of the application of a model-based cryolite ratio stabilization program, and the economic effectiveness gained through the program is shown.
