o:3924 Influence of chemical composition on the quality of castings obtained by the easy melting models en Abstract: This work presents the results of influence the chemical composition on the quality of castings, obtained using the wax models. After molding the wax models and melting the wax in a dryer, the mold cavity was filled with liquid metal. Four series of castings with the following chemical composition were cast: first series (Cu=90.5%; Sn=6.5%; Zn=3.0%), second series (Cu=83.7%; Sn=7.0%; Zn=9.3%), third series (Cu=90.2%; Sn=1.5%; Zn=3.0%; Pb=3.3%; Fe=2.0%) and fourth series (Cu=85.0%; Sn=5.0%; Zn=5.0%; Pb=5.0%). Based on the obtained results, a lack of filling was observed on a candlestick from the fourth series of castings. The quality of other castings is satisfactory, which refers to the external look. Faults in the form of voids are present, but minimal surface finishing allows obtaining the castings with relatively smooth surfaces. Keywords: Easy melting models, castings quality, wax model. 91552100 136847881 1552100 978-86-7827-052-9 2024-02-02T12:52:23.046Z 44 no 46 Milijana Mitrović Tehnički fakultet u Boru 0000-0001-7478-2453 Saša Marjanović Tehnički fakultet u Boru person 0000-0001-6930-2232 Jasmina Petrović Tehnički fakultet u Boru person 0000-0002-9131-339X Emina Požega Institut za rudarstvo i metalurgiju Bor person 0000-0001-6797-2435 Miloš Janošević Institut za rudarstvo i metalurgiju Bor person 0000-0002-0818-1235 application/pdf 1262946 https://unilib.phaidrabg.rs/o:3924 no yes 1 70 92000004 71A03 Proceedings: International October Conference on Mining and Metallurgy (53 ; 2022 ; Bor) 165 168 2022
