Original Abstract

Cooling intensity of working rolls is very important in industrial applications. Durability of these rolls strongly depends on proper cooling. In case of working rolls, not covered with a significant water layer, cooling is more effective with full cone nozzles than with flat jet nozzles. This paper is focused on the measurements of the cooling intensity for three different types of nozzles performed on an experimental roll which enables to measure thermal boundary conditions which occur on a real working roll. Two flat jet nozzles with different spray angles and same flow rate and one full cone nozzle with half flow rate for equal pressure were tested. The measurements showed that it is possible to achieve the same cooling intensities with half amount of water.
