| dc.description.abstract | Steel 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-en | Za 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 |
