Abstract

The sand cooling process before the mulling of green sand is a very important process in order to obtain the green molding sand with proper conditioning and performance characteristics. In this study, the high-temperature molding sand that exceeds 100 °C is investigated, and then the water cooling behavior of the molding sand is investigated by the experiment. The components of the molding sand are silica sand/artificial mullite sand and Na-type bentonite. The compactability index which is one of the properties of molding sand is controlled by the amount of water. Temperature and moisture content during sand cooling are studied to clarify the difference between natural (air) cooling and watering cooling methods. Further, theoretical analysis calculates the temperature drop of water cooling using heat transfer equations and the evaporation equation of water.
