Abstract
In order to increase manufacture efficiency and lower environmental impact, it is necessary to know the processes of consumption and emission of resource and energy, as the processes span out widely after originating from one process. In this paper, analysis and comparison of exergy were conducted in case when heater tube used in the molten aluminum was made of steel and ceramics. Exergy analysis was done for complete operation of aluminum casting. We then created a guideline for rationalization of casting process for efficient use of resource and energy.
