China Wholesale Induction System Manufacturers - induction hardening machine – Duolin Detail:

Products Description

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

Advantages of Induction 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.

Power	4-1500KW
Frequency	0.5-400KHz
Hardening Depth	0.5-10mm
Mechanical Fixture	CNC or PLC Control
Application	Gear, shaft, pipe, bearing, pump fitting, steel plate, roller,wheel,bars

Case depth [mm]	Bar diameter [mm]	Frequency [kHz]	Model
0.8 to 1.5	5 to 25	200 to 400	HGP30
1.5 to 3.0	10 to 50	10 to 100	Ultrasonic frequency series (10-30KH)
1.5 to 3.0	>50	3 to 10	Medium Frequency series (1-8KHz)
3.0 to 10.0	20 to 50	3 to 10	Ultrasonic/ Medium frequency series (10-30KH)
	50 to 100	1 to 3	Medium Frequency series (1-8KHz)
	>100	1	1 Medium Frequency series (1-8KHz)

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

What we need to know before offer induction hardening system?

1: The drawing of hardening parts

2: Material and hardening position

3: The hardness and hardening depth required

4: Require hardening production or not
