From the physical point of view, the casting speed affects the temperature field formation along the cast steel blank, e.g., the surface and corner temperatures as well as the solidification of the steel, e.g., the shell thickness, the isosolidus and isoliquidus curves, the metallurgical length and the width of the mushy zone. In order to achieve a particular steel structure, the temperature ranges in particular positions (e.g., due to the straightening), and to minimize the occurrence of defects, it is very important to pay attention to a proper determination of the casting speed. The aim of this paper is to investigate the impact of the casting speed on the temperature field formation of continuously cast steel billets, and on the aforementioned parameters. Three steel grades with various chemical compositions and the originally implemented numerical model of the transient temperature field of continuously cast billets in Zeleziarne Podbrezova in Slovakia were utilized for the analysis. The results proved the significant influence of the casting speed on the temperature field formation and on related parameters. The conclusions may be utilized, e.g., for the determination of the casting speed and for the setup of the caster"},{"@xml:lang":"sl","#text":"Pri kontinuirnem ulivanju je hitrost ulivanja eden od odločilnih parametrov, ki vplivajo na celoten proces proizvodnje jekla in na storilnost. Iz fizikalnega vidika hitrost ulivanja vpliva na nastanek temperaturnega polja vzdolž jeklene gredice, kot na primer na temperaturo robov in površine ulitega bloka, kot tudi na strjevanje jekla, kot na primer debelina strjene skorje, krivulje izosolidusa in izolikvidusa, metalurška dolžina in širina kašastega področja. Da bi dosegli želeno strukturo jekla, temperaturno področje v določenih položajih (npr. zaradi ravnanja) in da bi zmanjšali nastanek poškodb, je zelo pomembno, da smo pozorni na pravilno določitev hitrosti ulivanja. Namen prispevka je raziskati vpliv hitrosti ulivanja na oblikovanje temperaturnega polja pri kontinuirno ulitih gredicah in na že navedene parametre. Za analize so bila uporabljena tri različna jekla z različnimi kemijskimi sestavami in originalen numerični model prehodnega temperaturnega polja gredic v Železarni Podbrezova na Slovaškem. Rezultati potrjujejo pomemben vpliv hitrosti ulivanja na nastanek temperaturnega polja in s tem povezanih parametrov. Ugotovitve se lahko uporabijo na primer za določitev hitrosti ulivanja in za postavitev livne naprave"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-LCDINYBX","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-LCDINYBX"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-LCDINYBX/5fcb374c-4237-4e79-bcb0-6224a26b0e5a/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-LCDINYBX/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-LCDINYBX"}}}}
