Basic technological characteristics of a designed water-drop cooling device (irrigation density, its distribution on the cooled surface, and temperature dependence of the heat transfer coefficient) were determined. The effect of technological and design spraying jet parameters on the cooling capacity of large steel parts (hot rolling mill rolls) was obtained. Among the technological parameters under consideration was the water pressure in front of spraying jets and the number of spraying jets in a cooling device. The varied design parameters were the diameters of the spraying jet channels, the distance between the jets, the distance to the cooled surface, and the operating mode of the cooling device. The experimental data was used to obtain the correlation between listed parameters and basic technological characteristics of spraying jets in order to apply the uniform cooling of mill rolls during heat treatment.
