IGBT 120kw steel plate High Frequency induction hardening quenching machine

1. Why do steel plate need to be hardened?

The difference in the application industry makes the heat treatment process of the steel plate different. In order to meet the needs of the work, sometimes the steel plate needs to be annealed and heat treated. The most commonly used equipment for steel plate annealing is high-frequency induction heating machine, and the annealing effect is very good.

The high-frequency induction heating machine is produced with advanced IGBT modules, with very perfect functions and very simple operation. When the steel plate is annealed and heat treated, the heating speed is very fast. Such a fast heating speed effectively avoids the oxidation and decarburization of the steel plate during the annealing process, and ensures the annealing effect of the steel plate. What's better is that when annealing and heat-treating the steel plate, the whole steel plate can be annealed and heat-treated, or a part of the steel plate can be annealed and heat-treated according to the requirements, which can meet the requirements of different customers.

The induction coil of the high-frequency induction heating machine can be replaced freely, which enables the equipment to complete the heat treatment processes such as quenching, annealing, tempering, normalizing, and quenching and tempering, as well as welding, melting, hot assembly, hot disassembly and diathermy forming. Wait for the work, and truly realize the multi-purpose of the device.

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?

The selection of gear quenching equipment is related to gear diameter, gear module, gear quenching depth, gear quenching hardness, tooth thickness, gear material, and gear quenching daily output.
According to the gear diameter and gear thickness, the equipment power used for gear quenching can be determined.
According to the gear module and gear diameter, select the gear quenching process, single-tooth quenching or integral quenching.
According to the quenching depth of the gear, the oscillation frequency of the gear quenching equipment is selected and the above parameters are combined to determine the more suitable gear quenching equipment and gear quenching scheme.
