What is the difference between an intermediate frequency induction heating furnace and a high frequency induction heating furnace

Literally, the main difference between an intermediate-frequency induction heating furnace and a high-frequency induction heating furnace is the difference in frequency. Select the frequency according to the requirements of heat treatment and heating depth. The higher the frequency, the shallower the heating depth.


Difference between medium frequency induction heating furnace and high frequency induction heating furnace


The difference between an intermediate frequency induction heating furnace and a high frequency induction heating furnace can be recognized from three aspects:


First, the frequency range difference:


(1) Intermediate frequency: The frequency range is generally about 1kHz to 20kHz, and the typical value is about 8kHz.


(2) High frequency: The frequency range is generally about 40kHz to 200kHz, and usually 40kHz to 80kHz.


Second, the heating thickness


(1) Medium frequency: heating thickness is about 3-10mm.


(2) High frequency: heating depth or thickness is about 1-2mm.


Application


(1) Intermediate frequency: mostly used for heating large workpieces, large diameter shafts, large diameter thick-walled pipes, large modulus gears, etc.


(2) High frequency: It is mostly used for deep heating of small workpieces.
