What is high frequency induction heating machine?

The high-frequency induction heating machine uses the principle of electromagnetic induction, so that the alternating current passes through the induction coil to generate an alternating magnetic field, and the alternating magnetic field cuts the workpiece to generate eddy currents in the workpiece, so that the workpiece is heated. The HF induction heating machine ranges between 30 kHz and 80 kHz in frequency, with a heating depth of 0.5-2.5 mm, and is suitable for the heating of small and medium-sized parts.

What are the benefits of the HF induction heating power  supply?

The high frequency induction heating equipment is widely used and plays a very important role in the field of industrial heating. Compared with medium frequency induction heating machine, it has a relatively small heating depth of 0.5-2.5 mm. For this reason, it is mainly used for the heating of small and medium-sized workpieces and surface heating of workpieces.

  • Induction hardening: used for surface hardening of gears, shafts, auto parts, etc.
  • Induction brazing: used for brazing of hardware tools, diamond tools, saw blades and copper pipes.
  • Induction melting: used for melting 1-3kg of gold, silver, copper and other metals.
  • Induction heating: used for heating smaller size workpieces.

Induction heating head

Power requirements of induction heating head

The HF induction heating machine with power above 35 KW can be equipped with a movable induction heating head. Since a flexible cable is required to connect the machine when an induction heating head is used, power attenuation will occur. We need to use a machine with large power to ensure the heating performance.

Why is a water chiller required for the machine with an induction heating head?

The reason is that both the flexible cable and the heating head require a strong cooling effect. When an induction heating head is used, your induction heating equipment will need to be equipped with an industrial chiller. The strong cooling capacity of the industrial chiller can ensure that the water temperature in the flexible cable (with a length of 3-5 meters) and copper pipe of the induction heating head is below 35 °C.

How to cool the high frequency induction heating machine?

High-frequency induction heating machines generate a lot of heat during operation, so a cooling system is required to ensure continuous and stable operation of the machine. It can usually use two cooling methods to achieve different cooling effects.

Water tank + water pump

This simple water cooling system consists of a 2-5m³ water tank and a self-priming booster pump. After running the water pump, the cooling water in the water tank is pumped into the machine at a certain pressure, which can reduce the temperature of the machine and achieve the cooling effect.

Industrial chiller

The industrial chiller realizes cooling by using a compressor. Its refrigeration effect is so good that the machine can work in a stable and safe manner. If you use an induction heating head, it is better to use an industrial chiller to ensure that the water temperature in the copper pipe of the heating head is below 35 °C. It is small in size and is equipped with movable casters, which is very convenient.

How to install the high frequency induction heating machine?

The installation of the high-frequency induction heating machine is very easy. You only need to connect the required water cooling system or chiller, and then connect the single-phase 220V power supply (machines with a power of 15KW) or three-phase 380V (machines with a power of 25KW and above).
