Abstract

Although rapid stress-relieving and rapid tempering are well known processes, such as salt bath processing and particularly induction tempering, these terms are rarely used in conjunction with processes conducted in a convection oven. However, rapid heating technology has been developed for convection ovens where the use of a proprietary high-speed convection oven with turbulent flow is used to achieve not only faster processing times but improved quality and properties are obtained as well. In this paper, an fundamental overview of stress relieving and tempering and the development and use of proprietary rapid-heating technology for stress relieving and tempering operations will be provided. Selected applications related to the production of automotive components will also be discussed.
