160kw High Frequency Induction Heating Forging Queching Machine
1. high frequency induction heating quenching machine:
Induction heating is commonly used in the heat treatment of metal
parts. The most common applications are induction hardening of
steel parts, brazing and soldering in order to combine metal parts,
and annealing of parts to be softened in steel parts.
Induction heating can produce high power density, can reach the
required temperature in a short contact time, and can adjust the
magnetic field to precisely adjust the part to be heated, reducing
thermal deformation and damage.
The heat treatments described above can be used for local
hardening, resulting in parts with different properties.
A common application of hardening is to create an area that is
locally hardened and resistant to corrosion, but retains the
toughness of other parts. The depth of induction hardening can be
adjusted by adjusting the induction frequency, power density and
contact time.

Precautions:
The power supply for induction heating is generally low-voltage
high-current alternating current. The workpiece to be heated is
placed in an electromagnetic coil driven by alternating current,
usually with a capacitor, set as an LC circuit to generate
imaginary power, and the alternating magnetic field generates eddy
currents in the workpiece.
Magnetic materials enhance their heating effect because of their
hysteresis. Materials with high relative permeability (100–500) are
also easier to heat, and the hysteresis occurs below the Curie
temperature, where the material still maintains its original
magnetic properties. The high permeability of the workpiece below
the Curie temperature is quite useful. Temperature difference,
specific heat and mass all affect the heating of the workpiece.
The energy transfer of induction heating is affected by the
distance between the coil and the workpiece. The loss of energy
includes heat conduction, heat convection and heat radiation
between the work and the fixture.
The induction coil is generally made of copper tube, and it is
cooled by water. The diameter, form and number of coils affect the
efficiency and the shape of the magnetic field.
