What is the principle used in induction heating?

The induction heating works on the principle of transformer action, in which the primary winding which is supplied from an AC source is magnetically coupled to the charge, to be heated, which acts as a short-circuited secondary of a single turn.

Which induction is the principle of induction furnace?

Electromagnetic induction
The principle of induction furnace is the Induction heating: Induction heating is a form of non-contact heating for conductive materials. The principle of induction heating is mainly based on two well-known physical phenomena: Electromagnetic induction.

What are the three main components of an induction heating system?

An induction heating system comprises a tank circuit, a power supply, and a work coil.

What factors affect induction heating?

Operating Frequency Lower-frequency, higher-power systems are generally suited for heating larger parts that require through heating. Lower-power, higher-frequency systems are often the right choice for surface heating. As a general rule, the higher the frequency, the shallower the heating of the part.

What are the types of induction heating?

Induction heating:

  • Core type furnaces.
  • a. Direct core type induction furnace.
  • b. Vertical core type induction furnace.
  • c. Indirect core type induction furnace.
  • Core less type furnaces.

What causes heating in induction furnace?

In an induction furnace, the metal charge material is melted or heated by current generated by an electromagnetic field. When the metal becomes molten, this field also causes the bath to move. This is called inductive stirring.

Where is induction furnace used?

Induction furnace for metal of melting – is the most demand industrial equipment in the metallurgical industry. Such furnaces are ideal for melting ferrous, non-ferrous and precious metals.

What frequency is used in induction heating?

Radio frequency (RF) induction generators work in the frequency range from 100 kHz up to 10 MHz. Most induction heating devices (with induction frequency control) have a frequency range of 100 kHz to 200 kHz.
