Abstract

Mathematical models play a critical role in design, optimization, and control of water quenching treatment in metals processing. Modeling these processes correctly is predicated on accurately characterizing the heat transfer at the product surface throughout the quench operation, usually with a boiling curve. These curves are most often generated from time-resolved subsurface temperature measurements carried out during quenching, although data analysis is complicated by the ill-posed nature of the underlying problem. This paper reviews the best experimental and analytical practices that have been developed for recovering the boiling water curve through an inverse heat conduction analysis.
