Principle of medium frequency induction heating:
The intelligent medium frequency induction heating device is a power supply device that converts the power frequency 50HZ alternating current into an intermediate frequency (300HZ or higher to 20K HZ). The three-phase power frequency alternating current is rectified into a direct current, and then the direct current is converted into an adjustable intermediate frequency. The current supplies an intermediate frequency alternating current flowing through the capacitor and the induction coil to generate a high-density magnetic line in the induction coil, and cuts the metal material contained in the induction coil to generate a large eddy current in the metal material. The eddy current also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat.
Advantages of IF/MF induction heating equipment:
1. High heating temperature and non-contact heating
2. High heating efficiency - energy saving
3. Fast heating rate - less oxidation of the surface of the object being heated
4. Temperature is easy to control - product quality is stable and peace of mind
5. Can be locally heated - good product quality, energy saving
6. Easy to implement automatic control - effort
7. Good working environment - almost no heat, noise and dust
8. Less job footprint - high productivity
9. It can heat the workpiece with complex shape and wide application.
10. The workpiece is easy to heat evenly - the product quality is good.
Main Features of MF induction melting furnace:
1) Medium frequency induction melting furnace can be used for the melting of steel, stainless steel, iron, brass, copper, aluminum, gold, silver, platinum , zinc, metal alloys and so on.
2) Because of the stirring effect which caused by the magnetic force, the melting pool can be stirred during the melting course to ease the floating of the flux and oxides to produce high quality casting parts.
3) Wide frequency range from 1KHZ to 20KHZ, working frequency can be designed by changing the coil and compensating capacitor according to the melting material, quantity, stirring effect desire, working noise, melting efficiency and other factors.
4) Compared with SCR medium frequency induction furnace, it can save energy at least 20% and up.
5) Small and light weight, a lot of modes can be selected to melt different amount of metals. Not only it is suitable for the factory, but also suitable for the college and researching companies to use.
6) 24hours non-stop melting ability.
7) It’s easy to change melting furnace for different capacity, different material, different way of pouring out, to suitable for all kinds of requirements.
