dc.description.abstractThe article describes the design and optimization of the foundry production of porous metal. The formation of porous metal by infiltrating liquid metal into the mould cavity appears to be the fastest and most economical way. However, it is not possible to do it without proper production parameters. For this reason, a 3D model of a particular casting is first created in the Rhinoceros 4.0 software and then the entire production process is designed and optimized using the numerical simulation in the MAGMASOFT (R) 5.4 software. To create cavities in the casting, the use of sand cores is considered and the used unit bentonite mixture (UBM) becomes the mould material. With the simulations of pouring and solidification of the casting, the right conditions for the real production can be defined precisely; the time and financial costs connected with the production of non-conforming pieces can be saved. Thus, the aim is to ensure the production of sound castings that will find their use in the field of energy, specifically as heat exchangers.cs

dc.description.abstract-enV članku avtorji opisujejo dizajn in optimizacijo ulivanja poroznih kovinskih ulitkov. Ugotavljajo, da je formiranje porozne kovine s postopkom infiltracije raztaljene kovine v votlino livarskega modela najhitrejši in najbolj ekonomičen način. Toda tudi v tem primeru tega postopka ni možno izvajati brez ustreznih proizvodnih parametrov. Zato so avtorji najprej kreirali 3D model izbranega ulitka s programsko opremo Rhinoceros 4.0 in nato s programom MAGMASOFT® 5.4 izvedli numerično simulacijo dizajna in optimizacije celotnega proizvodnega procesa. Za izdelavo livarskega modela so uporabili peščena jedra in betonitno mešanico (UBM). S simulacijo polnjenja modela z raztaljeno kovino in strjevanja ulitka pri optimalnih pogojih so tako v realni proizvodnji lahko natančno določili čas in stroške, ter s tem prihranke, pri izdelavi ulitkov različnih zahtevnih oblik. Avtorji so tako omogočili proizvodnjo kvalitetnih ulitkov, uporabnih na energetskem področju, predvsem za izmenjevalnike toplote.cs
