Question

In salvaging of castings, cooling fluid used can be directly exposed to the hot castings to enhance heat transfer.

(a) True

(b) False

This question was addressed to me at a job interview.

Query is from Salvaging Techniques topic in division Salvage of Defective Castings of Casting-Forming-Welding I

Answer 1

Correct option is (b) False

For explanation: A cooling medium like coolant air from the compressor or steam is commonly directed to the casting along one or more casting surfaces. This flow for cooling is considered as backside flow, where the cooling medium is not directly exposed to the high temperature of surfaces of the casting.
