A Simulation Model for Aluminium Electrolytic Cells Concerning on Process Control

This paper describes the steps and the results of developing work in the field of mathematical modelling and dynamical simulation regarding aluminium electrolytic cells at Hungarian Aluminium Corporation (HUNGALU). Based on the main physical-electrochemical equations, a complex model has been developed. For the examined period of time, the alumina balance formation and the cell voltage alterations are the fundamental processes. The model parameters has been tunned for a real cell. In accordance with the plant situation, the regular operational events as well as the personnel’s interactions can determine the simulated process. The computer-based simulator can be applied for test and educational purposes. The research worker or a trained potroom assistant can watch and modify the forming process. It is an effective method to check the results of possible work routines. With the aid of the simulator, the planned control algorithms can be evaluated. Outlines of theoretical background, with examples of practical applications, are given in the paper.
