The operation principle of intermediate frequency induction furnace

In molybdenum powder before choose coal furnace and electric resistance furnace drying more boring, with the skills and the advance of science and technology, foreign molybdenum powder choose sense of intermediate frequency furnace more boring.

The operation principle of medium frequency induction furnace is boring. Application by medium frequency induction furnace boring first is Faraday electromagnetic induction principle representation, namely alternating current will attack induced current in the conductor, and then the conductor between the appearance of the onset of fever, induction heating is a good form of electric heating, one of the electrical energy into heat energy, the three-phase power supply by medium frequency induction power supply into intermediate frequency alternating current, when the alternating current turned round induction coil, it will attack alternating magnetic field sensor, that is to say, will attack range and direction are alternating magnetic flux Φ changes over time.

When the conductive metal tube is placed within the induction coil, according to Faraday's law of electromagnetic induction, metal tube inside will attack the corresponding е induction electromotive force, because the metal is a conductor, intermediate frequency furnace would be due to the existence of the induced electromotive force induced current I2, the induced current I2 is called eddy current, and on the basis of joule - lenz's law, the eddy current in metal pipe with resistance must be internal flow at will attack will surely heat Q, and then make the metal is heated.
