1. high frequency induction heating machine:
High-frequency heating, that is, induction heating, is a way to use
electromagnetic induction to heat electrical conductors (usually
metal), which will generate eddy currents in the metal, and cause
the metal to be heated by Joule due to resistance. The induction
heater includes an electromagnet through which high-frequency
alternating current passes. If the object has a large magnetic
permeability, it may also generate heat due to the loss of magnetic
hysteresis. The AC frequency used depends on the size of the object
to be heated, the type of metal, the degree of coupling between the
heating coil and the object to be heated, and the depth of
penetration.
2. Appliaction of induction heating machine:
· Heat treatment for various hardware and tools, such as plier,
wrench, hammer, ax,screwing tools and shear
· Heat treatment for various automobile and motorcycle fittings,
such as crankshaft,connecting rod, piston pin, chain wheel,
aluminum wheel, valve,rock arm shaft,semi drive shaft, small shaft
and fork.
· Heat treatment for various electric tools, such as gear and axes.
· Heat treatment for machine tools,such as lathe deck and guide
rail.
· Hardening for various hardware metal parts and machined
parts,such as shaft,gear chain wheel, cam,chuck and clamp etc.
· Heating for hardware molds, such as small-size mold, mold
accessory and inner hole of mold.
· Annealing of various stainless steel products, such as stainless
steel basin,annealed and extruded can, annealed folded edge,
annealed sink, stainless steel tube, tableware and cup.
· Forging of various other metal work pieces, such as round steel,
sheet/plate, pipe and others
3. Principle of IGBT induction heating machine:
Induction heating uses the induction current (eddy current loss)
generated by the conductor under the action of a high-frequency
magnetic field and the effect of the magnetic field in the
conductor (hysteresis loss) to cause the conductor to heat itself
for heating. When a current flows through a conductor, a magnetic
field is generated around it at the same time, and the
high-frequency current flows to an inductance coil (usually made of
copper tube) that is wound into a ring or other shape. As a result,
a strong magnetic beam with an instantaneous change in polarity is
generated in the coil. When the heated metal material is placed in
the induction coil, the magnetic beam will penetrate the entire
heated material and generate a large amount of energy in the heated
material in the opposite direction to the heating current. Eddy
current, due to the resistance of the heated metal substance to
generate Joule heat, the temperature of the metal substance itself
rises rapidly, thereby completing the heating of the metal
workpiece.
