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.
