Rational modes of high-temperature induction treatment of hard ferromagnetic bodies

We consider a new approach to computer simulation of the process of induction treatment of heat-sensitive hard ferromagnetic bodies, based on the well-known mathematical model of description of the physicomechanical processes in heat-sensitive bodies possessing different capacities for magnetization and polarization under the action of quasisteady electromagnetic fields. We have determined the rational parameters of high-temperature treatment of a cylinder (frequency and heat transfer coefficient in cooling), which enable one to warm the cylinder to the necessary temperature as soon as possible and afterwards to cool it in such a way that the maximum stresses in it in the course of treatment should not exceed the allowable stresses.
