1.	Which of the following is independent of the solidification time of the casting?(a) Mould material(b) Chaplets(c) Heat transfer coefficient(d) Mould wall temperatureThe question was posed to me at a job interview.I want to ask this question from Rate of Solidification in portion Cooling and Solidification of Casting-Forming-Welding I
Answer» Correct OPTION is (b) Chaplets Easy explanation: The SOLIDIFICATION time of the casting is generally dependent on the various parameters LIKE mould wall temperature, heat transfer coefficient at the metal and mould interface, mould wall THICKNESS and material of the mould. Chaplets are another part used for SUPPORTING the core in the mould.
