Abstract


The mathematical model of system «inductor-ingot» for investigation electromagnetic process at the continuous casting of aluminum ingots in a direct chill mold is considered in this article. Calculation at various parameters of a power line is made, electromechanical characteristics of stirrer are found. The frequency range at which electromagnetic influence of an inductor on a liquid heart of an ingot is most effective is established. The results of mathematical and physical modeling which have shown reliability of mathematical model are compared.
