The results of the numerical simulation of heat exchange at the cooling metal blank made of steel 30ChGSN2A are shown. The velocities of blank cooling with the flow of gas-liquid medium are defined. Cooling intensity changes depending on the blank motion speed opposite the flow of cooling medium are analyzed.
