Efficient and reliable super audio frequency (SF) induction heating machine

What is super audio frequency induction heating machine?

With the principle of electromagnetic induction, the SF induction heating machine produces a certain induced current on the surface of the workpiece to heat it. The SF induction heating machine can have more than 3 mm heating depth. It is mainly used for iron bars heating, auto parts hardening, etc.

What are the benefits of an SF induction heating machine?

  • Non-contact heating
  • Precise heating position
  • Infineon IGBT
  • Easy to realize automation
  • Complete fault alarm function

How to cool the SF induction heating machine?

There are three ways to cool an super audio frequency induction heating machine, and you can choose one of them based on your needs.

  • Simple water cooling system. It is composed of a water tank and a water pump. You need to prepare 1-2 water tanks with a volume of 3-5 m3 or above. You will also need a water pump that can meet the water pressure requirements of the machine. When the water cooling system operates, the water temperature at the water outlet of the machine shall be kept below 40 °C.
  • Closed cooling tower. The closed cooling tower is an internal circulating water cooling system, which includes a water tank, a blower, water-circulating pump and a spray pump. You just need to inject pure water into the cooling tower to make it work. It features a closed system, preventing water evaporation. Since the use of pure water, the limescale is greatly reduced. It is small in size and occupied and suitable for an indoor working environment.
  • Industrial chiller. The main working part of the industrial chiller is the compressor, which is of a stronger cooling effect and can effectively ensure the 24-hour continuous operation of the machine.
