Abstract

U ovom radu opisana je kratka povijest ljevarstva prema različitim povijesnim razdobljima.
Objašnjena su svojstva aluminija i njegovih legura, s posebnim naglaskom na njihove
industrijske primjene. Također, pojašnjeno je lijevanje u trajne kalupe, kokilni lijev, kalup,
postupak lijevanja te primjena samog postupka. Nadalje, opisan je softverski program za
računalnu simulaciju lijevanja ProCAST. U eksperimentalnom dijelu rada prikazana je
simulacija lijevanja aluminijeve legure AlSi12 u kokile te su prikazani rezultati simulacije
punjenja kalupa i skrućivanja odljevka. Simulacija je omogućila vizualizaciju procesa te
prikaz skrućivanja i mogućnost pojave poroznosti u odljevku

Abstract (english)

In this paper, a brief history of foundry practice across various historical periods was
described. The properties of aluminum and its alloys were explained, with a particular focus
on their industrial applications. Additionally, permanent mould casting process, mould, the
casting procedure, and the application of the process were clarified. Furthermore, the
ProCAST software program for computer simulation of casting was described. In the
experimental part of the paper, a simulation of casting aluminum alloy AlSi12 in a gravity die
is presented, along with the results of the simulation of mould filling and solidification of the
casting. The simulation provided a visualization of the process and showed the solidification
and the possibility of shrinkage porosity occurrence in the casting.
