Induction Heat Treatment

Induction heat treatment has been around for over 40 years. Heating is achieved without any direct physical contact and finds use in almost every industry where metals are used, be it in alloying, metal forming, tempering, hot working or shrink fitting. The technique is capable of heating materials at rates of temperature rise not normally associated with other methods, such as electrical resistance or gas heating, with a high degree of efficiency.
The induction heat treatment process relies on induced electrical currents within the material to produce heat. As there is no or limited physical contact, there are potential advantages in production. For example, there is less risk of contamination, a simpler heating arrangement and less insulation may be required.
