    Abstract

    Methods for determining the main service characteristics of cooling devices (irrigation density, its distribution on the cooling surface, and dependence of the heat-transfer coefficient versus temperature) are described. An investigation of technological and design parameters of spraying jets and their effect on cooling capability of large steel forgings (e.g., hot-rolling mill rolls) are presented. The technological parameters under consideration are water pressure in spraying jets and the number of spraying jets in a cooling device. The varied design parameters of spraying jets are the diameters of the channels in spraying jets, the distance between the jets, and the distance from the cooling surface. The results of the experiments were applied to obtain the dependency between technological and design parameters versus main service characteristics of spraying jets to develop and optimize the technology of heat treatment of large steel forgings. These relations were applied for modeling spray cooling of hot-rolling mill rolls.
