FIELD: electrical engineering.
SUBSTANCE: invention relates to an induction heating device, and can be used to heat products made of ferromagnetic steels before their subsequent processing on deforming equipment. Improving the energy efficiency of a two-frequency induction complex during heating of cylindrical steel ferromagnetic billets to plastic deformation temperatures is the technical result of the invention, which is achieved due to the fact that heating is carried out sequentially in two induction sections of the complex at frequencies of 500 Hz and 2400 Hz, while in the first section of the billet heated to the temperature of the Curie point, in the second section to the temperature of plastic deformation. The complex is equipped with a hydraulic drive for feeding blanks into induction heaters with a protective lining, a cooling system collector, and a temperature sensor installed at the outlet of the second section.
EFFECT: improving the energy efficiency of a two-frequency induction complex during heating of cylindrical steel ferromagnetic billets to plastic deformation temperatures.
