Principle of induction heating equipment:
Magnetic induction heating means that the alternating current generated by the induction heating power supply generates an alternating magnetic field through the inductor Baidu (i.e. coil), and the magnetic conducting object is placed in it to cut the alternating magnetic line of force, so as to generate alternating current (i.e. eddy current) inside the object. The eddy current makes the protons inside the object move at high speed and irregularly, and the atoms collide and rub with each other to produce heat energy, Thus, the utility model has the effect of heating articles. It is a heating method by converting electric energy into magnetic energy to make the heated steel body induce magnetic energy and generate heat. In this way, it fundamentally solves the problem of low efficiency of resistance heating through heat conduction, such as electric heating sheet and electric heating ring.  
In short, the principle of electromagnetic induction heating is to use the conversion between electricity, magnetism and heat energy to achieve the effect of heating the heated object itself. The essence of electromagnetic induction heating equipment is to use electromagnetic induction to generate eddy current in the column to heat the workpiece. It converts electric energy into electromagnetic energy, and then electromagnetic energy into electric energy. The electric energy is transformed into heat energy inside the metal, so as to achieve the purpose of heating the metal, so as to eliminate the harm and interference of open fire in the heating process. It is an environmental protection, Heating scheme advocated by the state.
