1.	Rapid cooling of strand surfaces of casting is mainly done to increase casting speed and productivity.(a) True(b) FalseI have been asked this question in an international level competition.This key question is from Solidification with Constant Surface Temperature topic in division Cooling and Solidification of Casting-Forming-Welding I
Answer» Correct CHOICE is (a) True Easiest explanation: For the CASTING line productivity and to increase casting speed, rapid cooling of strand surfaces must be EMPLOYED. It results in the development of THERMAL stresses and formation of surface cracks if the casting speed and cooling CONDITIONS or the arc of casting system are not appropriate for the casting process.
