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.
