Question

Reclamation may improve the casting quality, but does not affect the economic expenditure.

(a) True

(b) False

I had been asked this question in exam.

My query is from Sand Reclamation Techniques in division Sand Reclamation & Control Test of Casting-Forming-Welding II

Answer 1

The correct choice is (b) False

To explain: For the increasing cost of new sand and limited availability of high quality sand sources, reclamation is very important and necessary from the economic point of view. It reduces the cost involved in making of moulds and cores by keeping the quality equal to that produced by the new sand. Reclamation makes the processes economical and environmental friendly.
