The working principle of induction heating equipment:
Induction heating machine is a kind of three-phase power frequency
alternating current, rectified into direct current, and then the
direct current into adjustable current, supply the alternating
current flowing through the capacitor and the induction coil, and
generate high density in the induction coil. The magnetic line of
force is cut, and the metal material contained in the induction
coil is cut, resulting in a large eddy current in the metal
material.
This eddy current also has some properties of intermediate
frequency current, that is, the free electrons of the metal itself
flow in the metal body with resistance to generate heat. For
example, if a metal cylinder is placed in an induction coil with
alternating intermediate frequency current, the metal cylinder is
not in direct contact with the induction coil, and the temperature
of the energized coil itself is very low, but the surface of the
cylinder is heated to the point of redness or even melting , and
the speed of this redness and melting can be achieved only by
adjusting the frequency and the strength of the current. If the
cylinder is placed in the center of the coil, the temperature
around the cylinder will be the same, and the heating and melting
of the cylinder will not produce harmful gases or pollute the
environment with strong light.
