Аннотация: The article presents the results of a study of the modes of induction equipment designed for aluminum extrusion. Powerful single-phase inductors connected to a three-phase network cause asymmetry of currents and voltages, worsening the work of the rest of the equipment of the workshop, sharply increasing losses. The study of the moПоказать полностьюde of a single-phase inductor in a three-phase network was carried out by software using parametric circuit models built using hybrid analysis. Replacing approximate engineering methods with automated computational algorithms and mathematical modeling made it possible to perform a more accurate calculation. To increase control flexibility in practice, automation of balancing using a microcontroller is proposed. In the problem, the advantages and rationality of heating aluminum with electricity are shown, which allow us to proceed to a calculated estimate of the efficiency of electric heating in comparison with gas.
