Estimation of Filling Property of Cast Al–Si–Mg Alloy

摘要

Abstract Cast Al-Si-Mg alloys find broad applications in automobile components. Manufacture of defect free castings especially for long thin walled structures requires understanding of filling property. The filling property of cast alloy is studied using pin test piece through cylindrical cores for simulation followed by validation studies. Coating on the mould, pouring temperature and sand fineness are considered as parameters for this study. Simulation studies have been carried out using design of experiments. Results of casting simulation are in good agreement with validation studies. The parameters providing highest filling property are graphite coat on mould, AFS sand fineness 40 and pouring temperature with?+?20?°C for simulation and validation studies.
