AB  - The article describes heat removal from the hot surface by water. Method of cooling in a secondary zone of continuous casting of steel has a significant influence on a quality of continuously cast products mainly from the point of view of internal and surface defects. For this reason, a physical model of the secondary zone has been developed at the Department of Thermal Engineering, which enables testing of both water and water-air nozzles. During laboratory modelling cooling effects of a nozzle have been expressed by means of two parameters. Most commonly used parameter is spray intensity, infrequently heat transfer coefficient is determined. In comparison with the cold model the energy and time consumption at measurements on the hot model are several fold higher. Therefore, also was found correlations between the two models.
