Question

In solidification of large casting in an insulating mould, precise calculations are made for the analysis of freezing time of the complex contours of casting.

(a) True

(b) False

This question was posed to me in an internship interview.

My question comes from Solidification of a Large Casting in an Insulating Mould topic in portion Cooling and Solidification of Casting-Forming-Welding I

Answer 1

Right choice is (b) False

To elaborate: In solidification, to find out the freezing time of complex contours of casting, only observations are made without any use of calculations. This is mainly done to observe the basic features to know whether the analysis made underestimates or overestimates the actual freezing time of the casting material.
