Abstract

Ovaj rad se sastoji od dva dijela: teoretskog i eksperimentalnog.

U teoretskom dijelu ovog rada objašnjen je postupak lijevanja, osnovne greške prilikom lijevanja, te utjecaj pojila i hladila na skrućivanje odljevka.

U eksperimentalnom dijelu ovog rada provedeno je lijevanje aluminijske legure AlSi13 u pješčani kalup kroz pojila različitih dimenzija. Odljevci su bili u obliku palice kvadratnog presjeka. Promatran je i utjecaj hladila.

Na temelju rezultata može se zaključiti, da se odabirom... More pojila većih dimenzija i dodavanjem hladila znatno smanjuje pojava poroznosti u odljevku. Less

Abstract (english)

This paper consists of two parts: theoretical and experimental.
The theoretical part of this paper explains the casting process, basic casting deffects, and the influence of feeders and chills on the solidification of the casting.
In the experimental part of this paper, casting of AlSi13 aluminum alloy in a sand mold was carried out through feeders of different dimensions. The castings were in the shape of a square bars. The effect of chill was also analyzed.
Based on the results, it can... More be concluded that by choosing larger feeders and by adding a chill, the occurrence of porosity in the casting is significantly reduced. Less
