Abstract

Mathematical modeling methods are used to study the formation of temporary and residual stresses in spray hardening, differentiated thermal treatment, and induction hardening using commercial frequency current (CFC) heating. The principles for selecting cooling regimes in hardening are formulated to ensure minimal temporary and residual stresses and at the same time to obtained a hardened layer of a sufficient thickness. The advisability of using steel of enhanced hardenability such as steel 75Kh2GNMF in the production of large-sized forming rolls is demonstrated. A rational heat-treatment schedule has been developed for support rolls made from this steel.
