THE PHYSICAL ESSENCE OF THE ALIGNMENT PROCESS OF A FERROMAGNETIC WORKPIECE IN A SINGLE TURN IIS
Abstract
Investigation of straighten the dents on the ferromagnetic and non-ferromagnetic billet have been carried out with the help of an induction inductor system. The results of applying the effect of attraction were identical, which indirectly confirms the idea of the main role of the interaction of unidirectional currents, along with the acting magnetic attraction and the Lorentz repulsion. A mechanism is proposed that explains the possible causes of the attraction effect at frequencies up to 2 kHz: the induction current is pumped into the dent until the maximum is filled with vortex centrifugal currents and, as a consequence, is attracted to the tool screen. It is determined that the attraction becomes possible at low frequencies up to 2 kHz, when the pumping rate of the current is higher than the rate of its diffusion into the circuit. Increasing the operating frequency leads to the fact that the effect of attraction is replaced by repulsion.
