1. Application Ranges of induction hardening machine.
Induction heating power technology currently has the highest
heating efficiency, fastest speed for metal materials, and low
consumption and environmental protection. It has been widely used
in hot processing, heat treatment, hot assembly and welding,
smelting and other processes of metal materials in all walks of
life. It can not only heat the workpiece as a whole, but also heat
the workpiece locally; it can achieve deep heat penetration of the
workpiece, and it can only heat the surface and surface of the
workpiece; it can not only directly heat metal materials, but also
non-metallic materials. Indirect heating of materials, etc.
Therefore, induction heating technology will be more and more
widely used.
Fundamental:
Put the workpiece into the inductor (coil), when an alternating
current of a certain frequency is passed into the inductor, an
alternating magnetic field is generated around it. The
electromagnetic induction of the alternating magnetic field
produces a closed induced current in the workpiece—eddy current.
The distribution of the induced current on the cross section of the
workpiece is very uneven, and the current density on the surface of
the workpiece is very high and gradually decreases inward. This
phenomenon is called the skin effect. The electric energy of the
high-density current on the surface of the workpiece is converted
into heat energy, which increases the temperature of the surface
layer, that is, surface heating is realized. The higher the current
frequency, the greater the current density difference between the
surface layer and the inside of the workpiece, and the thinner the
heating layer. Surface quenching can be achieved by rapid cooling
after the temperature of the heating layer exceeds the critical
point temperature of the steel.

3. Induction Quenching Hardening Machine Application:
(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.
In the manufacture and production of mechanical equipment such as
automobiles and machine tools, there are many workpieces of
transmission mechanisms that need to bear large loads and frequent
start and stop, so the surface needs to have high hardness,
strength and wear resistance. Better toughness is required. For
example: gears, camshafts, valve rods, forward rods, automobile
half shafts, spline shafts, sprockets, optical shafts, guide rails,
profiling parts, etc. Therefore, it is necessary to perform surface
heat treatment on these workpieces. The traditional surface heat
treatment includes: surface carburizing, nitriding; carbonitriding;
surface quenching, etc. Compared with other heat treatment
processes, surface quenching has lower cost, higher efficiency and
more It is small, the operation is simpler, the advantages are very
obvious, and it is widely used in industrial production.
