Induction hardening is a form of heat treatment in which a metal part is heated by electromagnetic induction and then quenched, increase the hardness and brittleness of metal part.
Induction hardening equipment is widely used for the surface or inner hardening of steel.
Induction hardening process can be done in two different ways: static and scan hardening
• No physical contact hardening
• Scan/ Stationary hardening
• Short time (a few seconds) hardening increase production and improve quality
• CNC or PLC Control heating and cooling during hardening
Duolin Induction hardening equipments provide induction hardening solution for shaft, gear, roller, steel plate etc. The frequency of induction heating machines is from 1 KHz to 400KHz, which work with CNC or PLC quenching machines.

The main benefit of induction heating for hardening is that it takes just a few seconds.
Hardening test laboratory to check the hardening depth and hardness
1: The drawing of hardening parts
2: Material and hardening position
3: The hardness and hardening depth required
4: Require hardening production or not

The choice of induction heat treatment solution is related to the depth of the heating layer required by the workpiece. For the workpiece with a deep heating layer, should choose the medium frequency induction heating machine. For the workpiece with a shallow heating layer, should choose the high frequency induction heating machine.
The power supply equipment with low current frequency should be used; Another criterion for selecting a power supply is the machine power. As the heating surface area increases, the induction heat treating machine power required increases accordingly.
When the heating surface area is too large or the induction heat treating power supply is insufficient, the continuous heating method can be adopted to make the workpiece and the induction heating coil move relative, first heating and then cooling.
But it’s best to heat the entire surface at once. In this way, the waste heat of the workpiece core can be used to temper the hardened surface layer, thus simplifying the process and saving electric energy. The main function of the induction heating and quenching machine is to position the workpiece and carry out the necessary movement. An induction heat treating system for providing a quenching medium shall also be attached. CNC induction hardening machine tools can be divided into standard machine tools and special machine tools, the former is suitable for the general workpiece, and the latter is suitable for mass production of the complex workpieces.
In order to ensure the quality of induction heat treatment and improve the thermal efficiency, the inductor with proper structure must be designed and manufactured according to the shape and requirement of the workpiece. Common induction coils include outer surface induction heating coil, inner hole induction heating coil, plane induction heating coil, and so on.
