What is the relationship between the heating frequency of the induction heating furnace and the penetration depth?

The relationship between the heating frequency and the penetration depth of the प्रेरण हीटिंग फर्नेस should be considered. The higher the frequency of the intermediate frequency power supply, the shallower the penetration depth; the lower the current frequency, the deeper the penetration depth. The frequency is inversely proportional to the penetration depth. Therefore, for some large bars and large diameter round steel heating, the frequency is relatively low, which can shorten the heating time and improve the heating efficiency.
