1.	Chvorinov’s rule is commonly used for prediction of surface finish of the casting made in the mould.(a) True(b) FalseI had been asked this question during an interview.The doubt is from Solidification of a Large Casting in an Insulating Mould in chapter Cooling and Solidification of Casting-Forming-Welding I
Answer» The correct option is (b) False Explanation: Chvorinov’s rule is not USED for the aspect of finishing of the casting. It is mainly used to ensure that the casting made in the MOULD will SOLIDIFY before the riser. This is very necessary if the LIQUID metal within the riser is to effectively feed the casting to compensate for SOLIDIFICATION shrinkage.
