The coil's spatial-temperature evolution is calculated using the finite-difference method in the axial and radial directions, i.e., 2 dimensional. The model is verified by measuring the coil's temperature during reheating using 10 pre-installed thermocouples arranged in two lines of 5 thermocouples, each at a different coil radius. The sensitivities of the furnace-air temperature and the initial-coil temperature on the time to switch are determined, i.e., -52.5 s/°C and -55.5 s/°C, respectively. The mathematical model proved to be a multipurpose tool for different simulation-based reheating studies, while its industrial real-time application offers an even wider range of uses and capabilities: automatic coil-temperature control and observing reheating conditions on an industrial level"},{"@xml:lang":"sl","#text":"Članek obravnava uporabo matematičnega modela razvoja temperature v Al-kolobarju med toplotno obdelavo v peči s prisiljeno cirkulacijo. Razvoj prostorske temperature v kolobarju je izračunan z uporabo metode končnih diferenc v osni in radialni smeri. Model je bil preizkušen z merjenjem temperature v kolobarju med ogrevanjem s predhodno vgrajenimi 10 termoelementi, razporejenimi v dveh vrstah po 5 na dveh različnih premerih kolobarja. Ugotovljena je bila občutljivost temperature atmosfere v peči in začetne temperature v kolobarju v odvisnosti od peči: -52,5 s/°C oziroma -55,5 s/°C. Matematični model se je izkazal kot večnamensko orodje za različne simulacije ogrevanja, medtem ko industrijska uporaba v realnem času ponuja še širše področje uporabe in zmogljivosti: avtomatsko kontrolo temperature kolobarja, opazovanje razmer pri ogrevanju na industrijskem nivoju"}],"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-ZWFR22CV","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-ZWFR22CV"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-ZWFR22CV/dabbfdc8-2df8-4f8e-8d2f-a0accbd5f56b/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-ZWFR22CV/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-ZWFR22CV"}}}}
