Effect of Molten Metal Temperature on Mold Filling in Evaporative Pattern Casting

International Journal of Metalcasting Aims and scope Submit manuscript

Abstract

The mold filling rate during evaporative pattern casting was measured in a wide range of molten metal temperatures from 800 to 1450 °C. A polystyrene columnar foam was used as the foamed pattern, and bottom pouring was applied to design the casting. Tin alloy, copper alloy, and cast iron were used as molten metals to vary the molten metal temperature. The mold filling rate increased with increasing molten metal temperature at relatively lower temperatures. In contrast, the mold filling rate decreased with increasing molten metal temperature at high temperatures. These phenomena were verified by in situ observation.
