Induction Heating

โ€ขWorks like a transformer (Step down transformer โ€“low voltage and high current )
โ€“ electromagnetic induction principle

Induction Heating Advantages

โ€ข No contact is required between the work piece and the induction coil as the heat source
โ€ข Heat is restricted to localized areas or surface zones immediately adjacent to the coil.
โ€ข Alternating current (ac) in an induction coil has an invisible force field (electromagnetic, or flux) around it

Induction Heating Rate

โ€ขThe rate of heating of the work piece is dependent on the :
โ€ข Frequency of the induced current,
โ€ข The intensity of the induced current,
โ€ข The specific heat of the material (ability to absorb heat),
โ€ข The magnetic permeability of the material,
โ€ข The resistance of the material to the flow of current.
