Question

In the continuous casting process, there is a strong possibility of breaking of casting parts at the initial stage of solidification.

(a) True

(b) False

This question was posed to me in unit test.

This key question is from Solidification with Predominant Resistance in Mould topic in chapter Cooling and Solidification of Casting-Forming-Welding I

Answer 1

Correct answer is (b) False

To explain I would say: Continuous casting process nurtures the initial thin and fragile solid shells for the avoidance of breakout during the solidification of casting. And it also eliminates the surface and internal defects from the cast product by having the proper solidification dynamics in the casting process.
