Physical Simulation on Chill of Thick Walled Ductile Iron Casting for Spent-Nuclear-Fuel Container

Abstract:

Forced cooling measures need to be adopted in order to ensure the thick walled ductile iron casting solidification within the stipulated time. In this paper, the thick walled ductile iron casting for spent-nuclear-fuel container is used as the research object. The technology of outside mold has been identified in the actual production process. Through physical simulation experiment, the thickness of the outside the chills can be determined, and the cooling effect of chills is verified. The results show that cooling conditions have a decisive effect on the eutectic solidification, the residence time of eutectic platform and the time of casting solidification.
