Abstract

Predmet razmatranja rada je tehnologija centrifugalnog vertikalnog lijevanja, razvoj
centrifugalnog vertikalnog lijevanja kroz povijest. U radu je navedena problematika vertikalnog
centrifugalnog lijevanja, tehnološki postupak lijevanja te prednosti i nedostaci lijevanja.
Detaljnije je opisan tehnološki postupak lijevanja, uključujući pripremanje kalupa, lijevanje,
hlađenje te vađenje odljevka. Napravljen je kratki osvrt o skrućivanju materijala nakon lijevanja
što je jedna od najvažnijih pojava pri izradi proizvoda lijevanjem. Opisane su računalne
simulacije kao naophodan alat u industriji i proizvodnji. Eksperimentalni dio temelji se na
simulaciji lijevanja nehrđajućeg čelika EN 1.4301 izvedenoj u programu ProCAST nakon čega
su analizirani rezultati računalne simulacije. Rezultati simulacije su uspoređeni sa stvarnim
stanjem odljevka odlivenim u Laboratoriju za ljevarstvo na Fakultetu strojarstva i brodogradnje.
Napravljena je mikrostrukturna analiza odljevka. Rezultati simulacije podudaraju se sa
rezultatima stvarnog lijevanja.

Abstract (english)

The subject of this paper is the technology of vertical centrifugal casting and the development
of vertical centrifugal casting throughout history. The thesis presents the problems of vertical
centrifugal casting, technological casting process and advantages and disadvantages of casting.
The technological process of casting is described in more detail, including mold preparation,
pouring, cooling and casting removal. A brief review was made of the solidification of the
material after pouring, which is one of the most important phenomena in the manufacture of
products by casting. Computer simulations are described as a necessary tool in industry and
production. The experimental part is based on the simulation of stainless steel EN 1.4301
casting performed in the software ProCAST. The results of computer simulation were analyzed.
The simulation results were compared with the actual condition of the casting cast in the
Foundry Laboratory at the Faculty of Mechanical Engineering and Naval Architecture. A
microstructural analysis of the casting was performed. The simulation results match the actual
casting results.
