In this work an analysis of variation of the process parameters and their influence on the cast product quality is made. The statistics of actual process parameters and their deviation from the technological setpoints is performed. The influence of the winter - summer season on the cooling system is particularly covered in the analysis. The stored process parameters archive is used for establishing a database of the typical process parameters transients. In paralell to the system for data acquisition an experimentally verified simulator of the process has been developed. Based on the simulator and typical process parameters, an influence of the process parameters on the thermal field of the Al4.5CuPbBi, 0.285 m diameter billet is calculated. Variation of the temperature field is correlated with the cast quality for estimating the allowed process parameters deviations. The described work represents the continuation of the development of the system for data acquisition and monitoring towards the complete automatization of the DC casting process"},{"@xml:lang":"sl","#text":"V livarni IMPOL Slov. Bistrica smo v letu 1996 začeli na podlagi v celoti doma razvitega sistema spremljati in zapisovati parametre polkontinuiranega ulivanja Al-zlitin. V tem delu analiziramo spremembe procesnih parametrov med postopkom ulivanja in njihov vpliv na kvaliteto. Pri tem statistično obdelamo dejanske parametre ulivanja in njihov odmik od tehnoloških predpisov. Posebej analiziramo vpliv letnega časa na delovanje hladilnega sistema. Na podlagi arhiva podatkov vzpostavimo nabor značilnih prehodnih pojavov procesnih parametrov sistema. Vzporedno s sistemom za spremljanje procesnih parametrov smo razavili eksperimentalno verificiran simulator procesa. Na podlagi simulatorja in značilnih prehodnih pojavih sistema izračunamo vpliv procesnih parametrov na temperaturno polje gredice zlitine Al4.5CuPbBi premera 0.285 m. Variacije temperaturnega polja povežemo s kvaliteto ulitka in ocenimo dopustne meje odmika procesnih parametrov. Opisano delo je nadaljevanje razvoja sistema za spremljanje procesnih parametrov do popolne avtomatizacije"},{"@xml:lang":"sl","#text":"Nadaljuje se kot: Materiali in tehnologije"}],"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-SHLG0JXZ","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-SHLG0JXZ"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-SHLG0JXZ/22a38c4f-02ec-4c45-b721-5e00275aad74/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-SHLG0JXZ/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-SHLG0JXZ"}}}}
