dc.description.abstractThe traditional production of machinery and tools at ŽĎAS, a. s., and the increasing requirements placed on the final product, particularly those related to the internal quality of forgings, requires new technological measures for the ingot’s casting and solidification. The development and use of the new mould type 8K9.2 for tool-steel ingot casting has reduced the share of forgings with unacceptable quality. A substantial improvement has been achieved, especially in terms of the occurrence of defects, such as cavities and cracks in the ingot body.en
dc.description.abstract-enTradicionalna proizvodnja strojev in orodij v podjetju ŽĎAS, a. s., in naraščajoče zahteve pri lastnostih končnega proizvoda, ki so povezane z notranjo kakovostjo izkovkov, so zahtevale nove tehnološke ukrepe pri litju in strjevanju ingotov. Razvoj in uporaba nove kokile vrste 8K9.2 za litje jeklenih ingotov sta zmanjšala delež ingotov nesprejemljive kakovosti. Pomembno izboljšanje je bilo doseženo pri pogostosti napak, razpok in votlin v notranjosti ingota.en
