Investigation of Electrical and Energy Parameters of Induction Unit for Heating Steel Balls with Considering the Mutual Influence of Loading Elements

The paper presents a method for calculating the electrical and energy parameters of an inductor with a dispersed load in the form of a set of steel balls of the same diameter in the absence of electrical contact between them. The article also presents the results of experimental studies to determine the electrical parameters of the inductor loaded in the form of steel balls at a fixed temperature. The paper describes a method for determining the degree of influence on the integral electrical parameters of an element of a dispersed medium, consisting of conducting ferromagnetic balls, depending on the distance between adjacent elements of a medium placed in a uniform alternating electromagnetic field. The model takes into account the nonlinearity of the magnetic properties of the medium, which increases the accuracy of calculations. The considered dependencies can be used in determining the electrical resistance of a complex load during induction heating.
