120kw Shaft Induction Quenching Machine 35KHZ Induction Hardening Equipment

IGBT 120kw Gear High Frequency induction hardening quenching machine

1. Brief introduction of induction hardening machine

High-frequency quenching is mostly used for surface quenching of industrial metal parts. High-frequency current is passed through the coil to generate a high-frequency magnetic field, and an induced current is generated in the ferromagnetic material. Due to the skin effect, the induced current accumulates on the surface of the material to generate heat. , reaching the phase transition temperature. Chilling achieves the purpose of quenching.

3. Induction Quenching Hardening Machine Application:

Where is induction hardening used?
Induction is used to harden numerous components. For example: gears, crankshafts, camshafts, drive shafts, output shafts, torsion bars, rocker arms, CV joints, tulips, valves, rock drills, slewing rings, inner and outer races.

(1) For auto parts and motorcycle parts hardening.

(2) For machinery parts, like gears, transmission wheels, axles, shafts, spline shafts, ball stud hardening.

(3) For machine tools quenching, like guide rail machine tools hardening.

(4) For spanner, pliers, CNC machines, hammer, axe hardening etc.

4. What are the advantages of induction hardening?

Induction heating equipment, that is, equipment for induction heating of workpieces for surface quenching. The principle of induction heating: the workpiece is placed in the inductor, and the inductor is generally a hollow copper tube inputting intermediate frequency or high frequency alternating current (1000-300000Hz or higher). 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 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 within a few seconds, while the temperature of the core changes very little.

How to choose induction hardeing equipment?

Selection of induction heating frequency: The frequency is selected according to the requirements of heat treatment and heating depth. The higher the frequency, the shallower the heating depth.
1. The depth of high-frequency (above 10KHZ) heating is 0.5-2.5mm, which is generally used for the heating of small and medium-sized parts, such as small-module gears and small and medium-sized shaft parts. ​​
2. the intermediate frequency (1~10KHZ) heating depth is 2-10mm, which is generally used for the heating of shafts with large diameters and gears with large and medium modules. ​​
3. The depth of the hardened layer by power frequency (50HZ) heating is 10-20mm, which is generally used for diathermy of larger-sized parts and surface quenching of large-diameter parts (diameter above 300mm, such as rolls, etc.).
