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

isufficient amount of pure copper is to be heated for casting a large plate in an
open mold. The plate has dimensions: length = 20 in, width 10 in, and thickness 3
in. Compute the amount of heat that must be added to the metal to heat it to a
temperature of 2150°F for pouring. Assume that the amount of metal heated will be
10% more than what is needed to fill the mold cavity. Properties of the metal are:
density = 0.324 lbm/in3, melting point = 1981°F, specific heat of the metal = 0.093
Btu/lbm-F in the solid state and 0.090 Btu/lbm-F in the liquid state, and heat of fusion
= 80 Btu/lbm
