Original abstract
The surface temperature on the small radius surface in positions of straightening is an important parameter that can influence the surface quality of continuously cast steel slabs. Based on the detailed analysis the replacement of cooling nozzles pertaining to the small radius surface in the secondary cooling was performed on the caster in Evraz Vitkovice Steel due to the requirement on the increase of surface temperatures on the small radius surface of cast slabs. The results and experiences obtained after the replacement of cooling nozzles are compared to long-time operational data for the preceding setup of cooling nozzles that are used on the caster since 1995. The comparison is performed with the use of data acquired from the dynamic solidification model and with the use of the statistical operational data. The optimization of cooling nozzles setup is also discussed in the paper.
Czech abstract
Povrchová teplota na malém poloměru povrchu v pozicích rovnání je důležitý parametr, který může mít vliv na kvalitu povrchu plynule odlévaných ocelových desek. Na základě podrobné analýzy nahrazení chladicích trysek, které se týkají malého poloměru povrchu sekundární chlazení byla provedena na kolečka v Evraz Vítkovice Steel vzhledem k požadavku na zvýšení povrchové teploty na malém poloměru povrchu litých desek. Výsledky a zkušenosti získané po nahrazení chladicích trysek je ve srovnání s dlouhodobých provozních dat za předchozí nastavení chladicích trysek, které se používají na kolečka od roku 1995.Srovnání se provádí s použitím dat získaných z dynamického modelu tuhnutí a s využitím statistických provozních dat. Optimalizace chlazení trysek nastavení je popsána v dokumentu.
