Abstract
Tema ovog diplomskog rada je analiza poroznosti tlačno lijevanih odljevaka od legure aluminija. Rad se sastoji od teoretskog i eksperimentalnog dijela. U teoretskom dijelu ukratko je opisano visokotlačno lijevanje i njegove komponente – proces lijevanja, strojevi za tlačni lijev, kalupi (alati) za lijevanje, parametri tlačnog lijeva, prednosti i nedostaci te još neke bitne karakteristike koje se tiču visokotlačnog lijeva. Nakon toga, dan je pregled najčešćih legura aluminija od koji se rade odljevci prvenstveno za automobilsku industriju te su opisana svojstva svake od legura. Na kraju teoretskog dijela opisane su greške na odljevcima s kojima se najčešće susreće u ljevaonicama te je opisano kako prepoznati grešku i korigirati proces kako bi greška nestala. Eksperimentalni dio rada uključuje optimiranje jedne pozicije (odljevka) koja ima problem s poroznosti. Optimiranje je napravljeno tijekom studentske prakse u firmi LTH Metalni Lijev d.o.o. u Benkovcu. Problem je rješavan kroz nekoliko koraka koji uključuju optimiranje parametara lijevanja na stroju za tlačno lijevanje, izradu simulacija i promjenu konstrukcije alata. Na kraju su dobiveni komadi s puno manje poroznosti. Cijeli proces optimizacije napravljen je onako kako se u praksi rješava problem i postupak je detaljno opisan u eksperimentalnom dijelu ovog rada.
Abstract (english)
The topic of this thesis is the porosity analysis of die-cast aluminum alloy castings. The paper consists of a theoretical and an experimental part. In the theoretical part, high-pressure die casting (HPDC) and its components were briefly described - the casting process, die-casting machines, molds (tools) for casting, die parameters, advantages and disadvantages high-pressure die casting process. After that, an overview of the most common aluminum alloys from which castings are made primarily for the automotive industry was given, and the properties of each alloy were described. At the end of the theoretical part, the common die casting defecets were described, along with methods for identifying and rectifying them to eliminate the errors. The experimental part of the work includes the optimization of one position (casting) that has a porosity problem. The optimization was made during the student internship at the company LTH Metalni Lijev d.o.o. in Benkovac. The problem was solved through several steps, which include optimization of the casting parameters on the die casting machine, creating a simulation and changing the construction of the tool. In the end, castings with much less porosity were obtained. The entire optimization process was done how the problem is solved in practice and the procedure was described in detail in the experimental part of this paper.
