WHAT IS INDUCTION HEATING:

Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold, silver, aluminum, or carbide. An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor called eddy currents. The eddy currents flow through the resistance of the material, and heat it by Joule heating. In ferromagnetic and ferrimagnetic materials, such as iron, heat also is generated by magnetic hysteresis losses. The frequency of the electric current used for induction heating depends on the object size, material type, coupling (between the work coil and the object to be heated), and the penetration depth.

An important feature of the induction heating process is that the heat is generated inside the object itself, instead of by an external heat source via heat conduction. Thus objects can be heated very rapidly. In addition, there need not be any external contact, which can be important where contamination is an issue.

THE PRAMETERS OF GYD-100AB MEDIUM FREQUENCY INDUCTION HEATING MACHINE For FORGING:

THE ADVANTAGES OF THE INDUCTION HEATING MACHINE:

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 operating 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.

10. Comprehensive full load design: it can work continuously for 24 hours.

11. Small size and light weight: it has a weight of only several dozens of kilograms, of which, the limited floor space can effectively 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.

HOT FORGING:

Hot forging aims to fabricate the work pieces of certain temperature (different materials require different temperatures) into other shapes through forging press with the help of punch press, forging machine or other equipments, for instances, hot extrusion of watch case, watch flan, handle, mold accessory, kitchen and table ware, art ware, standard part, fastener, fabricated mechanical part, bronze lock, rivet, steel pin and pin.

We have established an R&D system. It is supported by advanced engineers and professional workers, who are especially engaged in researching and developing the machinery of middle or high frequency induction heating and high frequency inverter electrolysis and galvanization power supply. Since we owned strong technique development capability, our factory has been insisting on producing new product and new craftwork to assure our leading position on technique in this field.

Under the effort of several years, our factory has produced series of high quality products in various categories. We can also exclusively produce these products on your requirement to meet you need. Our middle or high frequency induction heating equipment is produced for special voltage condition of some countries. For instance, there is single-phase 110V, three-phase 220V induction heating equipment for America and Japan and three-phase 415V, 440V induction heating equipment for such southwestern Asia countries as Malay and Thailand.
