Abstract
POSTUPAK ZA LIVENJE POD PRITISKOM METALNIH DELOVA U PENU ZA JEDNOKRATNU UPOTREBU, naročito od aluminijuma i njegovih legura prema kome se potopi model dela za livenje od organske pene u kalup čiji zidovi su ograničeni sa kupatilom suvog peska koji ne sadrži vezivo, kalup se napuni sa metalom u tečnom stanju, koji zameni penu i progresivno očvršćava, a zatim se primeni rastući izosatički gasni pritisak istovremeno na kalup i metal što pre posle konačnog punjenja, nazna čen time, da se primenjeni pritisak povećava do vrednosti izmedju 1,5 i 10 MPa. Prijava sadrži još 3 zavisna zahteva.PRESSURE PROCESSING METALLIC PARTS FOR SINGLE-USED FOAM, especially aluminum and its alloys, by which the mold of the organic foam casting mold is immersed in the walls, bounded by a dry sand bath containing no binder, the mold is filled with metal in liquid state, which replaces the foam and progressively solidifies and then applies increasing isosatic gas pressure simultaneously to the mold and metal as soon as possible after final filling, increasing the applied pressure to a value between 1.5 and 10 MPa. The application contains 3 more dependent requests.
