How Important is Temperature for Induction Heat Treatment?

Jul 16, 2016

Heating temperature is one of the important parameters of induction heat treatment technology. The selection and control of induction heating temperature is the main point to ensure heat treatment quality. Heating temperature of induction heating equipment is different due to the difference of metal materials and heat treatment purposes. However, in order to get high temperature structure, the heating temperature is usually over the phase-transition temperature. In addition, when the surface temperature of metal workpieces reaches the specified temperature, the temperature needs to be kept for some time to make surface and inner temperature consistent so as to complete the transition of microscopic structure. This time is called heat preservation period.

As to high-energy density heating and surface heat treatment, its heating speed is very fast and there is no need of heat preservation period, while chemical heat treatment need a little longer heat preservation time.
