| Popis: | Consideration has been given to the most widespread three-dimensional formulations of a mathematical model of the process of inducing eddy currents in ferromagnetic materials. Two procedures have been proposed to calculate temperature fields of induction heating devices in a mode of automatic proportional-integral-differential temperature control, which makes it possible to considerably reduce the consumption of computer time with ensuring acceptable accuracy. The first procedure provides for a successive conduct of electromagnetic and thermal analyses with the "scaling" of heat releases from the eddy currents at the stage of control. In the case of shortage computational resources it is possible to use the second procedure which involves a thermal model under the assumption of a uniform release of heat in the region of inductors and is only applicable for the inductors placed inside heated bodies. Using the calculation of temperature fields in press plates, molds, and vulcanized products as an example, the authors have shown the necessity of taking account of the period of stabilization of a temperature field in developing and operating heating plates. |
