Investigation of the Process Parameters on Hot Rolling of Al 7178-SiC Metal Matrix

Rolling process is more important processes in manufacturing. Hot rolling is mainly used to produce sheet metal or cross section such as aerospace structure and automotive parts etc.. In present study Al 7178 was taken as matrix metal and silicon carbide powder (40 µm size) is selected as reinforcement to produced to composites with 3%, 6% and 9% of Sic with stir casting process. The metal matrix were fed to Hot rolling. In this investigation influence of the process parameters such that thickness of rolling plate, speed of rollers, percentage of a thickness reduction and temperature of rolling plate during Hot rolling process. Taguchi method of design experiments were conducted to optimise the process parameters which effect on properties of AL 7178 metal matrix.
