Abstract
Casting process enables the economical manufacture of products with intricate geometry to near net shape. Almost all metals and alloys are produced from liquids by solidification. The objective of the study is to find the impact of pouring temperature and chill thickness on aluminum–silicon (LM6) castings. The casting parameters such as pouring temperature and external mild steel and copper chills are considered for the experimental work. The simulation has been done using AutoCAST-X1 software to identify the hot spot and locate the shrinkage defect. The experimentation has been conducted with no chill, mild steel chills and copper chills with varying thicknesses. In this work, an attempt has been made to obtain the rapid cooling rate of aluminum–silicon (LM6) castings using external chills. It is observed that the chill has a significant effect on the properties of the castings. The design of the experiment has been set up, and experiments were conducted as per the full factorial array. Castings are made by controlling the casting process parameters at three different levels. The regression models of ultimate tensile strength and hardness have been developed with predictors. The better mechanical properties were obtained by controlling pouring temperature and the application of external chills.
