Question

The axis of rotation of the mould should be horizontal for the casting of long pipes in centrifugal casting.

(a) True

(b) False

I had been asked this question during an online exam.

The above asked question is from Centrifugal Casting in section Special Casting Techniques of Casting-Forming-Welding I

Answer 1

Correct choice is (a) True

Easy explanation: In centrifugal casting, the axis of rotation of the mould can be horizontal, vertical or any angle in between. Generally, very long pipes are cast with a horizontal axis, whereas short pieces are more conveniently cast with a vertical axis, as it requires less area for the casting operation.
