1.	Which of the following is used for the controlling of heat flow in the casting process?(a) Mechanical resistance(b) Biscuit(c) Chaplets(d) Thermal resistanceI got this question at a job interview.Query is from Solidification with Predominant Interface Resistance topic in division Cooling and Solidification of Casting-Forming-Welding I
Answer» Correct answer is (d) Thermal resistance To EXPLAIN: In the casting PROCESS, the heat flow is generally controlled by the thermal resistance of the metal-MOULD interface. These interfaces can be of convex, concave or plane shape, depending on the heat flow rate required for the casting. These processes mainly INCLUDE PERMANENT mould casting and die casting.
