Abstract

For the purpose of improving the casting yields of ductile iron castings, the casting conditions for riserlese design were investigated with 150mm cube. As the important casting conditions, chemical composition, pouring temperature, mold rigidity and cooling rate were confirmed. 1. We could obtain the sound castings with the hypereutectic ductile iron. 2. In order to reduce liquid contraction, the pouring temperature should be low as much as possible 3. We could obtain the sound castings through using the rigid mold without mold cavity deformation 4. The modulus of the castings should be 2.5cm one or larger.
