Determine the volume of molten metal

Reference no: EM131420558

For the steel ring of preceding Problem 11.10, deter-mine the volume of molten metal that must be poured into the mold, given that the liquid shrinkage is 0.5%, and the solidification shrinkage and solid contraction.

Problem 11.10

A horizontal true centrifugal casting process is used to make aluminum rings with the following dimensions: length = 5 cm, outside diameter 65 cm, and inside diameter = 60 cm.

(a) Determine the rotational speed that will provide a G-factor = 60.

(b) Suppose that the ring were made out of steel instead of aluminum. If the rotational speed computed in part (a) were used in the steel casting operation, determine the G-factor and

(d) Would this rotational speed result in a successful operation?
