1.	Superheating is the only main consideration for the existence of no contact resistance between the metal and mould.(a) True(b) FalseThis question was posed to me in class test.Enquiry is from Solidification with Predominant Interface Resistance in section Cooling and Solidification of Casting-Forming-Welding I
Answer» Correct answer is (b) False Best explanation: For no contact RESISTANCE between the metal and mould, the solidification process is CONSIDERED by assuming that the thermal resistance at the INTERFACE is of over-riding IMPORTANCE. In this KIND of cases, superheating is not considered for the temperature distribution in the casting solidification.
