Abstract

The paper presents an experimental work carried out while studying the cooling of hot steel surfaces by spray nozzles. Links between the experiment and its evaluation are discussed. A relative movement of the quenched surface in relation to the nozzle is typical for all experiments. Two experiments with different configuration are used, speeds are discussed. The first type - experiment on a rotating roll cooled by water nozzles - applies a circumferential velocity of the roll within a range from 1 to 5 m/s. The second experiment studies a situation where a flat cooled surface moves linearly in relation to a twin fluid nozzle. The speed applied here varies from 1 to 3 m/min. Experimental results of the first experiment find their application usually in rolling and th
