Chills in casting pdf
WebChill casting is used to produce castings from iron, steel, aluminum, magnesium, and other alloys. It is particularly effective in the production of castings for aluminum and … 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.

Webtypes, from a casting temperature of about 1450 °C, W 1 and W 2 wedges at lower cooling moduli of 0.11 and 0.2113 will give a much worse chilling. The iron will therefore not be able to produce grey iron without appropriate ladle treatments. The effect of the FeSi addition is obvious as treated irons gave overall lower values for the chill ...
