Chills are used in casting where the part is likely to form

Chills are used in casting where the part is likely to form a cavity.They are used in thicker regions to increase the solidification rate.

A. False

B. True

Solution

TRUE

To maximize the heat tranfer rate a metalic object is provided called CHILL. Chill is inserted into the cavity created due to removal of pattern and inserted in moulding sand.

By changing the direction of the chill the direction of solidification also changes.

Chill is a metalic object which is conductive so heat transfer rate is high compare to moulding sand.
