Abstract
U ovome radu prikazane su simulacije lijevanja odljevaka od legure AlSi7Mg u pješčani kalup i kokilu. Teorijski dio rada prikazuje postupak lijevanja gdje je naglasak stavljen na kalupe izrađene od svježe kalupne mješavine. Osim pješčanog lijeva opisan je postupak gravitacijskog lijevanja u kokilu te elementi uljevnog sustava i pravilno oblikovanje vertikalnog uljevnog sustava s ušćem odozdo. Osim ovih postupaka napravljena je podjela i opis aluminijevih legura te su navedeni razlozi zbog kojih je poželjno uvođenje simulacija u ljevačke procese i elementi koji su potrebni kako bi se simulacija mogla provesti. U zadnjem dijelu rada prikazani su rezultati simulacija lijevanja odljevaka od legure AlSi7Mg u pješčani kalup te rezultati gravitacijskog lijevanja u kokilu s različito konstruiranim uljevnim sustavima. Radiografska ispitivanja na stvarnim odljevcima potvrdila su da nema poroznosti skupljanja što je u skladu s napravljenom simulacijom lijevanja odljevka u pješčani kalup.
Abstract (english)
This thesis presents casting simulations of AlSi7Mg alloy castings in sand mould and permanent mould. The theoretical part of the thesis shows the casting process where the emphasis is placed on green sand moulds. In addition to sand casting, the process of gravity die casting was described. Elements of gating system and proper design of vertical gating system with bottom gate were also described. In addition to this processes, classification and description of aluminium alloys has been made. The reasons are given why it is desirable to introduce simulations into the casting processes and the elements necessary for the simulation to be carried out. The last part of the thesis presents the results of casting simulation of AlSi7Mg alloy castings in sand moulds and results of gravity die casting with different designs of gating system. Radiographic tests confirmed that there is no presence of shrinkage porosity what is in accordance with casting simulation of casting in sand mould.
