| dc.description.abstract | 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 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-en | Tijekom 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 |
