160kw electric igh frequency induction heating machine for forging
1. Principle of high-frequency induction heating machine:
The workpiece is placed in the inductor, which is generally a hollow copper tube that inputs intermediate frequency or high frequency alternating current. The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, it is strong on the surface, but very weak in the interior, and it is close to 0 in the center. This skin effect is used. , the surface of the workpiece can be heated rapidly, and the surface temperature rises to 800-1000ºC in a few seconds, while the temperature of the core rises very little.
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.
