WebIn controlled solidification, one of the important factors that affects heat transfer from the solidifying casting is the resistance offered at the casting/chill interface. In the present investigation, heat transfer analysis during solidification of Al-12%Si (LM 13) alloy is carried out by collecting temperature history of the solidifying casting. WebDirect Chill (DC) casting is a critical process in the production of aluminum ingots. It is a casting process in which w ater-cooled molds initiate the first par t of solidification. Thereafter , water spr ays impinge on the shell of solid alumin um enclosing the liquid core . To obtain higher productivity and better quality products , A chill is an object used to promote solidification in a specific portion of a metal casting mold. Normally the metal in the mould cools at a certain rate relative to thickness of the casting. When the geometry of the molding cavity prevents directional solidification from occurring naturally, a chill can be strategically placed to help promote it. There are two types of chills: internal and external chills. greg dodd northern gas networks
