High Frequency Induction Heating Equipment The Faster The Melting Speed, The More Obvious The Power Saving Effect.
Overview of high frequency induction heating equipment:
The application in the field of high-frequency welding is an alternating current with a frequency of 100 kHz to 800 kHz. The power frequency of 50 or 60 Hz is first converted into DC, which is converted into high-frequency AC through the oscillation formed by using a vacuum tube combined with a channel capacitor or through an inverter composed of high-frequency power crystal devices MOSFETs (metal oxide field effect transistors), and forms a steel pipe welding heating source through an output device.
