1.	For a single riser in the casting system, the chill should be placed at the ends of the riser.(a) True(b) FalseI have been asked this question in an internship interview.Question is taken from Riser Placement topic in section Cooling and Solidification of Casting-Forming-Welding I
Answer» Correct answer is (a) True For explanation I would say: To have PROPER directional solidification and to maintain the RISER mechanism, the chill USED should be placed at the ends of the riser. When more than one riser is used in the casting SYSTEM then the chill should be placed at the midway between the TWO risers to have accurate and systematic solidification.
