Metal Casting

Metal casting is described as a manufacturing process in which a mold cavity is produced by sand, and molten metal is filled inside a mold cavity. The desirable shaped object is achieved after the solidification of molten metal. Large metal objects like machine beds, motor bodies, and others can easily be manufactured using metal casting. The place or shop where metal casting is performed is called foundry.

Question

Q2: True centrifugal casting is performed horizontally to make large diameter
copper tube sections. The tubes have a length= 1.0 m, diameter= 0.25 m, and
wall thickness = 15 mm. (a) If the rotational speed of the pipe = 700 rev/min,
determine the G-factor on the molten metal. (b) What volume of molten metal
must be poured into the mold to make the casting if solidification shrinkage
and contraction after solidification are considered? Solidification shrinkage
for copper = 4.5%, and solid thermal contraction = 7.5%?
