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

The solidification time of a casting is proportional
to)? , where V is the volume of the casting and A is the

Q.B3. As part of a project, students have been asked to cast an Aluminium disc for use as a flywheel. The flywheel is part of an engine development project and needs to be 200 mm in diameter and 20 mm thick. Green sand casting will be used. The shrinkage associated with this metal and process is 5% at the solidification stage and further 3 % on cooling to room temperature. Aluminum has a density of 2710 kg/m³ and a melting temperature of 660°C. The pouring temperature is 700°C while the specific heat of aluminum is 887 J/kg.K. The latent heat of fusion of Aluminum is 396 kJ/kg. From previous experiments the Chorinov constant for the mold was found to be 10 s/mm². Determine: a.) The dimensions of the pattern (diameter and thickness) that will need to be made for this part (ignore riser and sprue). b.) The time it will take for complete solidification of the part. c.) Assuming an electric furnace at 10% efficiency is used to heat the metal and it takes around 2 hours achieve pouring…
