Compared with ordinary electric furnaces, induction heating has the advantages of fast heating speed, small deformation of the workpiece and high hardness of appearance. The principle of induction heating is that when the light flows through the inductor, because of the electromagnetic induction, an alternating magnetic field is generated in the workpiece in the inductor, and the alternating magnetic field induces an induced potential, which forms a current in the workpiece. That is, eddy current. The density of the eddy current is scattered in the workpiece, and the closer to the surface current of the workpiece, the higher the frequency is, the larger the surface current is. Therefore, when the heating is applied, the power concentration is at the surface of the workpiece. Because this part of the surface temperature rises the fastest. As the surface temperature of the workpiece increases, the resistivity of the workpiece increases. When the temperature reaches the Curie temperature (768 ° C), the electric power is concentrated on the inner layer... Therefore, induction heating is a step-by-step heating process, and the precise selection of heating power, office frequency and heating time can achieve the required quenching temperature. According to the different depth of quenching, it can be divided into three types: High frequency heating facilities: Intermediate frequency heating facilities: Power frequency induction heating facilities: With long cycle life and high energy desity, Lithium Polymer Battery is advanced rechargeable battery and power for various customer electronic products, such as phone, smart security products, POS machine, GPS tracker and so on.

It has a set of equipment that converts the power frequency from 50 cycles/second to high frequency (70000~1000000 cycles/second) (it is generally considered appropriate to use a vacuum tube high frequency generator) with a quenching depth of less than 3 mm.
It also has a set of equipment that converts the power frequency from 50 cycles/second to medium frequency (500~10000 cycles/second). It is usually an intermediate frequency generator (low power factor) and a thyristor inverter with a quenching depth of about 5 mm. .
The power frequency of the inductor is the same as the frequency of the grid, ie 50 cycles/second, so the energy can be extracted directly from the grid + ç¾ç¼•, and the quenching depth is above 10 mm. Not enough is the power factor is too low.
