One option for computing this thermal load is to measure the temperature and to study the thermal load through the heat flux. A unique work roll was made for testing different process conditions, such as rolling velocity, roll cooling, skin cooling and reduction. This work roll was tested on a real, hot-rolling, continuous pilot line. Two types of temperature sensors were embedded in the work roll in order to measure the temperature and these gave very detailed information about the development of the temperature inside the work roll. A time-dependent heat flux was computed using an inverse heat-conduction task with a detailed numerical model. The surface-temperature history was also obtained from this computational model. These boundary conditions give detailed information about the influence of different process conditions and allow a computation of the temperature field in the work roll. The paper describes the measuring equipment, details of the used temperature sensors, the inverse heat-conduction task for computing the thermal-surface boundary conditions and the results obtained from hot-rolling conditions"},{"@xml:lang":"sl","#text":"Zaradi dolge dobe trajanja delovnih valjev je pomembno sledenje njihovih toplotnih obremenitev, ki jih je težko izmeriti. Ena od opcij izračuna termičnih obremenitev je merjenje temperature in študij toplotne obremenitve s toplotnim tokom. Izdelan je bil valj za preizkušanje različnih procesnih pogojev, kot so hitrost valja, ohlajanje valja, ohlajanje skorje valja in odvzem. Ta delovni valj je bil preizkušen na realni kontinuirni vroči valjarniški pilotni liniji. V delovni valj sta bili vgrajeni dve vrsti temperaturnih senzorjev, da bi izmerili temperature, in obe sta dali zelo podrobno informacijo o poteku temperature v njem. Izračunana je bila časovna odvisnost toplotnega toka z natančnim matematičnim modelom inverznega toka toplote. Iz tega računskega modela je bila dobljena tudi zgodovina temperature površine. Ti mejni pogoji so dali natančno informacijo o učinku različnih parametrov procesa in omogočili izračun temperaturnega polja v delovnem valju. V članku je predstavljena merilna oprema, detajli uporabljenih senzorjev temperature, inverzno prevajanje toplote za izračun mejnih termičnih razmer na površini in rezultati, dobljeni pri valjanju"}],"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-BZREE9AY","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-BZREE9AY"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-BZREE9AY/1f96cc82-4c45-4b68-aead-9f4fee8bfca2/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-BZREE9AY/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-BZREE9AY"}}}}
