Application and development of medium frequency induction furnace

Medium frequency induction furnace is used to heat metal workpiece by electromagnetic induction. It is the main heating equipment in mechanical processing industry. It has the advantages of fast heating speed, energy saving and environmental protection.

1. The application of medium frequency induction furnace makes the capacity of smelting furnace in foundry industry from small to large, from small to tens of kilograms to tens of tons, even some smelting furnace capacity has exceeded 30t, holding furnace capacity has exceeded 50t.
2. The application of medium frequency induction furnace makes the heating power of medium frequency induction furnace from small to large, generally from 100kW to 15000kw, and even has a large medium frequency power supply of 20000KW.
3. The development of medium frequency induction furnace power supply from parallel resonance to series resonance makes the medium frequency induction furnace develop from a set of medium frequency power supply driving a smelting furnace body to “one pulling two” (one melting, one insulation, series circuit) until “one pulling three”.
4. Medium frequency induction furnace has made great progress in steelmaking. Good results have been achieved in the production of stainless steel with medium frequency induction furnace and steel refining or AOD furnace.
5. In recent decades, with the development of crystal turn tube technology, the medium frequency power supply in medium frequency induction furnace has also made an important breakthrough. At present, the medium frequency power supply has developed to “three-phase six pulse”, “six phase twelve pulse” and “Twelve phase twenty-four pulse”. The reliability of Thyristor Medium frequency induction furnace is high, and the power supply device can be synchronized with the treatment of higher harmonic.
6. The application of automatic control of medium frequency induction furnace can easily use PLC programming, and the control system can effectively control the electronic parameters of medium frequency induction furnace, especially in the forging heating production line and quenching and tempering heating production line, which makes great contribution to the construction of intelligent chemical plant.

With the development of science and technology and the progress brought by technology, the technology of medium frequency induction furnace is becoming more and more mature. In forging industry and metal quenching and tempering heating, it liberates manpower, reduces production cost, stabilizes quality and improves production efficiency. Medium frequency induction furnace is still exploring heating applications in other industries, with a bright future.
