Abstract

U radu su navedena i opisana pravila lijevana aluminijskih legura i prikupljeni podatci o konstrukciji i izradi uljevnog sustava za jednokratni pješčani kalup.

U teoretskom dijelu ovog rada opisano je deset pravila ljevanja kako bi odljevci bili što veće kvalitete i kako bi se izbjegla pojava grešaka prilikom lijevanja. Izrađeno je više CAD modela vertikalnog i horizontalnog uljevnog sustava te su izvšene njihove simulacije lijevanja i skručivanja u simulacijskom programu QuickCAST. Odabrane su najčešće verzije vertikalnog i horizontalnog uljevnog sustava te su isti uljevni sustavi poboljšani kako bi se usporedili rezultati kvalitete lijevanja sa simulacijama. Nakon toga izrađeni su drveni elementi uljevnih sustava dimenzija korištenih u simulaciji, pomoću kojih su izrađeni kalupi od svježe kalupne mješavine u koje su lijevani stvarni odljevci.

Na kraju eksperimentalnog dijelu rada može se zaključiti da je dobra podudarnost rezultata simulacije i stvarnog lijevanja.

Abstract (english)

In this paper are listed the rules od casting aluminum alloy and described all data for the construction and development of the gating system for one-sand mold are collected.

Theoretical part of this work have studied ten rules of castings for making high quality casting and to avoid the occurrence of errors during casting. We made several CAD models of vertical and horizontal gating system, and performed their simulation of casting and solidification in simulation program QuickCAST. Chosen are the most common version of the vertical and horizontal gating system, and we have the same filler systems improve to compare results of quality casting. Wooden patterns od gating system were manifactured in dimensions used in the simulation.

They are made wooden models runners measuring system used in the simulation, with which they made in real castings. Moduls for casting of real castings were made using green and sand mixture. Simulation results are in good agreement with the casting results.
