How to design the height of the induction coil of the ಇಂಡಕ್ಷನ್ ತಾಪನ ಕುಲುಮೆ?

The height of the induction coil of the induction heating furnace is mainly determined according to the power P0 of the heating equipment, the diameter D of the workpiece and the determined specific power P:

a. For one-time heating of short-axis parts, in order to prevent overheating of sharp corners, the height of the induction coil should be less than the height of the parts.

b. When the long-axis parts are heated and cooled locally at one time, the height of the induction coil is 1.05 to 1.2 times the length of the quenching zone.

c. When the height of the single-turn induction coil is too high, the heating of the surface of the workpiece is uneven, and the middle temperature is much higher than the temperature on both sides. The higher the frequency, the more obvious it is. Therefore, double-turn or multi-turn induction coils are often used instead.
