Naceur, M. Kchaou, H. Ksibi] Temperature distribution in a 42CrMo4 steel test piece during local cooling from 900°C with a water jet from an injector is studied. Heat flux distribution with action of a jet on the side surface of a test piece is analyzed. The hardness of a test piece side surface is measured and the microstructure of its different cross sections is studied. Numerical software is used in order to describe cooling kinetics for the side surface of a cylindrical test piece by a fine water jet. Operating parameters are optimized for cooling by analyzing the effect on them of the number of injectors and their arrangement. Conditions are revealed for improving cooling efficiency for cylindrical test pieces with injectors.
