dc.description.abstractMethod 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 as well as zonal segregations. At the department of thermal engineering, a physical model of the secondary zone has been developed, which enables testing of both water and water-air nozzles. During laboratory measurements cooling effects of a cone nozzle have been expressed by means of three parameters. Most commonly used parameter is an admission characteristic, infrequently heat transfer coefficient is determined and newly a measuring of dynamic impact of the cooling water has been introduced.en
dc.description.abstract-enTijekom kontinuiranog lijevanja čelika, hladenje sekundarne zone od značajnog je utjecaja na kvalitetu odljevaka sa aspekta unutraš njih i površinskih pogrešaka te u kontekstu zonske segregacije u materijalu. U odjelu za termoenergetiku razvijen je fizikalni model sekundarne zone, kojim je omogućeno ispitivanje vodenih sapnica i sapnica za hladenje mješavinom vode i zraka. Tijekom laboratorijskih mjerenja, efekti hladenja koničnom sapnicom izraženi su trima parametrima. Nejčešći je pritom parameter admisijske karakteristike, ponekad se odreduje i koeficijent prijelaza topline a recentno je uvedeno mjerenje dinamičkog utjecaja rashladne vode.en
