Abstract:
     An electromagnetically inductive heating method features that the three-phase magnetic conductor composed of magnetic steel and iron core forms a closed three-phase magnetic loop. When three-phase main-frequency power supply is connected to three-phase windings surrounding the iron core, the magnetic steel is quickly heated by eddy current and magnetic lag generated by three-phase alternative magnetic flux in it, that is, electric energy is directly converted into magnetothermal energy. Its advantages are simple strucutre, load balance for three phases and high thermal efficiency.
