Induction Heating

The document discusses induction heating which is a process where heat is produced inside conducting materials when placed in a varying magnetic field. It causes eddy currents that generate heat. Applications include surface hardening of steel, soldering, drying paints, and melting materials. Important features are localized heating, high rates, and no skilled labor or smoke required.

Induction Heating
Induction heating is the process in which heat is produced inside a conducting material (magnetic & non-magnetic), according to the Faraday’s law of
electromagnetic induction, whenever a conductor is placed in a varying magnetic flux, the EMF (voltage) is induced in that conductor. The work piece of
metal that is to be heated is placed within the work coil, high frequency voltage is applied to the work coil this set up an alternating flux or field. The
workpiece cuts the flux and voltage is induced in it, which is called eddy current, this eddy current passes through the workpiece resulting in heat.

The work works as primary coil of the transformer, while the workpiece (which is heated) works as a secondary of the transformer. With this method the heat
is produced in steel 50 times faster than heat can be transferred into the metals in the furnace and resulting temperature is more uniform throughout, since
higher temperature is used in induction welding. Non-magnetic materials are also heated through induction method.

Induction Heating

Important Features of the Induction heating


1. The heat is control near the surface of the work coil.
2. Very high heating rate can be obtained.
3. Skilled labours are not required of the operation.
4. At working place there is no smoke and dust.

Applications of induction heating


There is some important application of the indication heating.

1. Surface harding of steel


2. Soldering
3. Drying of paints
4. Melting of costly materials.
