Способ относится к электротермии и может быть использован в порошковой металлургии, в частности для штучного нагрева неспеченных порошковых заготовок из ферромагнитного материала при совмещении операции кратковременного нагрева и спекания перед горячей штамповкой. Предлагаемый способ позволяет снизить энергозатраты за счет совмещения автоматической стабилизации температуры поверхности заготовки с автоматическим поддержанием косинуса сдвига фаз между током и напряжением индуктора.The method relates to electrothermal and can be used in powder metallurgy, in particular for heating of green powder blanks of ferromagnetic material, when combining the operation of short-term heating and sintering before hot stamping. The proposed method allows to reduce energy consumption by combining automatic stabilization of the surface temperature of the workpiece with automatic maintenance of the cosine of the phase shift between the current and the voltage of the inductor.
