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.

A thermal dynamic model of the electrolyzer is considered and certain production events are modeled. Results of variations in production parameters after controlling actions are considered.

The article describes an example of a casting and rolling complex. A program has been developed for calculating the temperature of the metal in the casting and rolling complex sites which is based on a mathematical model for controlling the water cooling of a rotary mold in TIA Portal software using an S7-1200 microprocessor controller. Presents the structure and user interface of the program. The program blocks of the rotary mold, as well as the section of water and air cooling are developed, which include design and thermophysical parameters necessary for calculating according to the mathematical model. In this way, the replacement of any of them with a similar one with modified parameters is possible without making changes to the program structure. The program can be used to debug control algorithms.
