dc.description.abstractInadequate information on available natural moulding sands in Nigeria resulted to the use of the sand for casting without recourse to their suitability. This practice resulted to poor casting quality and underdevelopment of Nigerian foundry industry. In this study, the properties of Oyun natural moulding sand were evaluated to determine its suitability for sand casting. The chemical and physico -mechanical properties of the sand samples were examined using America Foundrymen’s Society (AFS) guidelines. The results of the chemical analysis showed that the sand contained SiO₂and, Al₂O₃from 84.49 to 84.58% and 7.17 to 7.22% respectively, with smaller proportions of other elements such as NaO₂and K₂O, CaO, Fe₂O₃, MgO and TiO₂. The physico-mechanical properties of the sand were clay content (14.96 -15.79 %), moisture content (8.15 –8.48%), grain fineness number (83.40 –89.24), green compressive strength (77.31 –79.73 KN/m²), dry compressive strength (200.24 –214.65 KN/m²) and refractoriness (above 1300°C). These results were within the AFS standard recommendation values for non-ferrous metal casting. Hence, Oyun moulding sand was found suitable as mould sand for various types of casting of metals like grey steel, aluminum, bronze, brass and light steels. Effective utilization of this sand for foundry applications will help to improve the economy of Nigeria and subsequently aid in reducing social problems as result of unemploymenten_US

Description:
The chemical analysis showed that Oyunmoulding sandwas silica sand with chemical compositions within the AFS acceptable range values for moulding sands. Thus, Oyunnatural moulding sand was suitable for casting of metals, most especially with low meltingtemperature. There were presencesof some elements such as CaO, Fe₂O₃, MgO, and TiO₂apart from the main constituents which most of them serve as impurities. The present of these impurities such as CaO, K₂O, and NaO₂lowers the refractoriness, which may affect the suitability of the sand for casting of ferrous casting, though suitable for nonferrous casting.Though, these elements were in smaller proportion. The results of the physico-mechanical tests agreed favorablywith the AFS recommended values for casting some metals, most especially non-ferrous metals. Therefore, the properties make the sand suitable for metal casting
