1. Application of high frequency induction quenching machine:

Induction hardening is the use of electromagnetic induction to generate eddy currents in the workpiece to heat the workpiece.
Detail applications are stated as follows:
1. Quench for various hardware and tools, such as plier, wrench, hammer, ax, screwing tools and shear (orchard shear).
2.Quench 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.
3. Various electric tools, such as gear and axes.
4. Quench for machine tools, such as lathe deck and guide rail.
5. Quench for various hardware metal parts and machined parts, such as shaft, gear (chain wheel), cam, chuck and clamp etc.
6. Quench for hardware molds, such as small-size mold, mold accessory and inner hole of mold.

3. Induction Quenching Hardening Machine Classfication:

The induction hardening types are divided into: power frequency, low frequency, intermediate frequency, super audio frequency, high frequency, and ultra high frequency. The suitable frequency is selected according to the hardening depth. The greater the depth of the hardened layer, the lower the required frequency, and vice versa, the higher.

4. How Does Induction Heating Work?:
When a magnetic field changes near a metal or other conductive object, a flow of current (known as an eddy current) will be induced in the material and will generate heat. The heat generated is proportional to the current squared multiplied by the resistance of the material. The effects of induction are used in transformers for converting voltages in all sorts of appliances. Most transformers have a metallic core and will therefore have eddy currents induced into them when in use. Transformer designers use different techniques to prevent this as the heating is just wasted energy. In this project we will directly make use of this heating effect and try to maximise the heating effect produced by the eddy currents.

Annealing (tempering and modulation):

1. The heat source is on the surface of the workpiece, the heating speed is fast, and the thermal efficiency is high
2. Because the workpiece is not heated as a whole, the deformation is small
3. The heating time of the workpiece is short, and the amount of surface oxidation and decarburization is small
4. The surface hardness of the workpiece is high, the notch sensitivity is small, and the impact toughness, fatigue strength and wear resistance are greatly improved. Conducive to exert the potential of materials, save material consumption, and increase the service life of parts
5. The equipment is compact, easy to use and good working conditions
6. Facilitate mechanization and automation
7. Not only used in surface quenching, but also in penetration heating and chemical heat treatment.
