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…
A flat plate is to be cast in an open mold whose bottom has a square shape of 12.5 cm by 12.5 cm. The mold is 7.0 cm deep. A total of 350 cm³ of molten aluminum is poured into the mold. Solidification shrinkage is known to be 6.25%, which is a volumetric contraction, not a linear contraction. Table 7.1 lists the linear shrinkage due to thermal contraction after solidification. If the availability of molten metal in the mold allows the square shape of the cast plate to maintain its square dimension until solidification is completed, determine the final dimensions (width and height) of the plate.
A sprue in a sand mould has a topdiameter of 20 mm and height of 200mm. The velocity of the molten metalat the entry of the sprue is 0.5 m/s.Assume acceleration due to gravity as9.8 m/s2 and neglect all losses. If themould is well ventilated, the velocity(upto 3 decimal points accuracy) of themolten metal at the bottom of the sprueis ______ m/s.
