dc.description.abstractSteel making at ŽĎAS, a.s. using secondary metallurgy technology makes it possible to produce liquid metal with high levels of metallurgical cleanliness. During the casting and subsequent cooling of forging ingots, the steel solidification takes place. Directional material solidification, grain size, chemical heterogeneity and discontinuities can have a negative effect on the products’ final properties. The comparison of the chemical composition based on a numerical calculation with the heterogeneity of the real ingot has proven the possibility of using MAGMA software to model the casting and solidification of ingots for open-die forgings made from 26NiCrMoV115 steel.en
dc.description.abstract-enZa uporabo tehnologije sekundarne metalurgije se v ŽĎAS izdeluje tekoče jeklo z veliko metalurško čistostjo. Med ulivanjem in ohlajanjem kovaških ingotov se izvrši strjevanje. Usmerjeno strjevanje, velikost zrn, kemična heterogenost in diskontinuitete lahko negativno vplivajo na lastnosti končnega proizvoda. Primerjava kemične sestave z numeričnim izračunom heterogenosti realnega ingota je dokazala možnost uporabe softvera MAGMA za modeliranje ulivanja in strjevanja ingotov za prosto kovanje iz jekla 26NiCrMoV115.en
