Operating Principle

Frequency conversion electromagnetic induction heating, commonly known as induction heating, is a method of heating metal materials.

It operates on the principle of electromagnetic induction to transform the power frequency power supply into one within a specific range.

This heating technique is mainly suitable for metal hot working, heat treatment, welding, and melting processes. Moreover, this type of heating technology also has applications in other fields.

In the packaging industry, it can be used for the sealing of aluminum foil in the medical and food industries.

In the realm of semiconductor materials, it serves purposes like extruding monocrystalline silicon and heating to attach metal parts for automotive glass.

The fundamental components of an induction heating system are the induction coil, an AC power source, and the workpieces.

The induction coil can be fabricated into diverse shapes according to the different items to be heated. It is linked to the power source, which supplies alternating current to the coil.

The alternating current in the coil generates an alternating magnetic field that passes through the workpieces, thereby producing the eddy currents required for heating.

Advantages of Induction Heating Equipment

1. Fast heating: the minimum rate of heating is less than 1 second (rate of heating is available for adjustment and control).

2. Wide coverage of heating: it can be used to heat various metal parts (replace removable induction coil as per different perating switches).

3. Easy installation: it can be used once it is connected with power source, induction coil as well as water supply pipe and rising pipe; it is small in size and light in weight.

4. Easy operation: you can learn to operate it within several minutes.

5. Fast start-up: it can be started to perform heating operation on condition that water and power supply is available.

6. Low power consumption: As compared with conventional vacuum tube high frequency equipments, it can save the power by approximately 70%.

The smaller the size of the work piece is, the lower power consumption

would be.

7. High effectiveness: it has such features as uniform heating (it is applicable to adjust the spacing of the induction coil to ensure the appropriate temperature as required

by each part of work piece), fast warming and limited oxic horizon, and can guard against any waste after annealing.

8. Comprehensive protection: it has such functions as overpressure, over-current, overheat and water shortage alarm indications as well as automatic control and protection.

9. Controllable temperature: it is applicable to control the temperature for heating work pieces as per the preset heating time, and thereby control the heating temperature at a certain technical point.

save the workshop space.

12. Elimination of high voltage: it requires no step-up transformer which may produce approximately ten thousand voltage, and

thus can ensure the maximum safety.
