20.500.12556/DKUM-66802 Casting process optimization by the regression analysis applied on the wear resistant parts molding Optimizacija procesa lijevanja pomoću regresijske analize primijenjene na kalupljenje dijelova otpornih na habanje Conducting a comprehensive research of the casting process of wear resistant parts (white hard casting), a significant correlation is established between the technological parameters (temperature, aging time in the mold and coolant flow) and the final product hardness. The fundamental theory of Box-Wilson's gradient method marked the baseline for the foreseen researches. The method defines the coherence of the process parameters, since their dispersion in the examined process is relatively small. Main target of the experiment was a definition of the optimal casting conditions. Therefore the different technological routes are identified and the casting process is modified until the best outcome is achieved. Target function was initially in a hypothesized form, while later on evolved into a consistent form due to the application of experiment-statistics, process optimization and process management based on empirical feedback. Provodeći sveobuhvatno istraživanje procesa lijevanja dijelova otpornih na habanje (lijevanje bijelog željeza), uspostavljena je značajna korelacija između tehnoloških parametara (temperatura, vrijeme starenja u kalupu i protok rashladnog sredstva) i tvrdoće finalnog proizvoda. Osnovna teorija Box-Wilsonove metode gradijenta činila je osnovu za predviđena istraživanja. Ta metoda definira koherentnost parametara procesa budući da je njihova disperzija u ispitivanom procesu relativno mala. Glavni je cilj eksperimenta bila definicija optimalnih uvjeta lijevanja. Stoga su identificirane različite tehnološke rute i modifikacije u procesu lijevanja dok se nije postigao najbolji rezultat. Ciljna je funkcija u početku imala oblik hipoteze, ali je kasnije dobila konzistentan oblik primjenom statističkih podataka dobivenih eksperimentom, optimizacijom procesa i upravljanjem procesom na bazi empirijske povratne veze. casting mathematical model quality management wear resistance litje matematični modeli management kakovosti obrabna odpornost true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-11 11:56:40 2017-07-11 11:58:01 2022-08-01 13:11:13 2019-07-11 15:59:25 2012 0 0 str. 141-146 št. 1 Letn. 19 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1330-3651 621.941:004.89 15346181 18034966 1330-3651 URN:SI:UM:DK:PYNWZMPQ Tehnicki_vjesnik_2012_Slavkovic_et_al._Casting_process_optimization_by_the_regression_analysis_applied_on_the_wear_resistant_parts_moldi.pdf Tehnicki_vjesnik_2012_Slavkovic_et_al._Casting_process_optimization_by_the_regression_analysis_applied_on_the_wear_resistant_parts_moldi.pdf 1 18CBFB1129E5B862B5366B2CAE27E66C 812d913e7299a656fee91fc642a802977ba9a1fcef008cb15b14582da166de95 65095600-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/ad39ad44-b78b-447e-a3c0-9ce035853962 https://dk.um.si/Dokument.php?lang=slv&id=114008 http://hrcak.srce.hr/79170 1 https://dk.um.si/Dokument.php?lang=slv&id=114007 Fakulteta za strojništvo 0 0 0
