WebControlling the rate of cooling during the start-up phase of the Direct-Chill (DC) casting process is challenging and crucial as this region is highly prone to defect formation. During the DC casting process, primary cooling in the mold is followed by secondary cooling in which the partially solidified shell impinges with cooling water from an ...

An effort has also been made to evaluate the effect of chill material on the soundness of the castings obtained. The required composites were prepared using LM-25 Aluminum alloy as matrix material in which different weight percent of …
http://www.industrialmetalcastings.com/casting_chill_casting.html 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.
