A round casting is 0.2 m in diameter and 1 m in length. Another casting of the same metal iselliptical in cross section, with a major-to-minor axis ratio of 2, and has the same length andcross sectional area as the round casting. Both pieces are cast under the same conditions.What is the difference in the solidification times of the two castings?arrow_forward

- Imagine that you work in a foundry and are asked to calculate the solidification time of particular component. This part has rectangular cross sectional area with a width-to-thickness ratio of 4 and the same length and cross-sectional area of a cylinder of the same metal. The cylinder has a diameter of 250 mm and a length of 1.5 m and solidifies in four minutes. If both parts are cast under the same conditions, a) Calculate the solidification time the rectangular cross-section casting.arrow_forwardA flat plate is to be cast in an open mold whose bottom has a square shape that is 200 mm by 200 mm. The mold is 40 mm deep. A total of 106 mm3 of molten aluminum is poured into the mold. Solidification shrinkage is known to be 6.0%. The linear shrinkage due to thermal contraction after solidification is 1.3%. If the availability of molten metal in the mold allows the square shape of the cast plate to maintain its 200 mm by 200 mm dimensions until solidification is completed, determine the final dimensions of the plate.arrow_forwardYou are designing a mold to cast the solid part shown in the figure below from pure copper. If the runner diameter is 1 in and the molten copper velocity in the runner is 0.5 in/s. If the Chvorinov Constant is 50 S/in².
