9.Coil protection frame

Generally speaking, the principle of induction furnace design is:

Put a metal cylinder in the induction coil with alternating intermediate frequency current. The metal cylinder is not in direct contact with the induction coil. The temperature of the energized coil itself is already very low, but the surface of the cylinder is heated to red, or even melted, and this speed of redness and melting can be realized by adjusting the frequency and the strength of the current.

If the cylinder is placed in the center of the coil, the temperature around the cylinder will be the same, and the heating and melting of the cylinder will not produce harmful gases or pollute the environment with strong light.

Induction Furnace Design Features

Melting device series


Induction furnace is mainly used for smelting steel, iron, copper, aluminum and alloys, etc. It has the characteristics of high melting efficiency, good power saving effect, uniform metal composition, less burning loss, fast temperature rise, and easy temperature control. It is suitable for various metal smelting occasion.


(Intermediate frequency) induction furnace

Constant power output, faster melting speed and more obvious power saving effect.

The zero-pressure frequency sweep software starts, which can better meet the requirements of frequent starts.

Comprehensive protection measures, such as overcurrent, overvoltage, current limiting, pressure limiting, water shortage, and lack of protection, make the equipment run reliably under the premise of ensuring the melting speed.

Simple operation, suitable for various casting processes.

As we all know, the induction furnace rectifies the three-phase power frequency alternating current to direct current, and then converts the direct current into an adjustable current, which supplies the alternating current flowing through the capacitor and the induction coil, thereby generating high-density magnetic lines of force, and Cut the metal material contained in the induction coil.

Therefore, a good plan needs to make a corresponding induction furnace design plan according to the characteristics of the metal material, power level, temperature, etc.
