Question
What is the main advantage of using centrifugal casting for producing cylindrical parts?a) Excellent surface finishb) High dimensional accuracyc) Uniform grain structured) Efficient removal of impurities
Solution
The main advantage of using centrifugal casting for producing cylindrical parts is c) Uniform grain structure.
In centrifugal casting, the molten metal is poured into a spinning mold. The centrifugal force pushes the metal against the mold wall and forces impurities towards the center. As the metal cools, it solidifies from the outside in, creating a uniform grain structure. This results in parts with superior mechanical properties compared to parts produced by other casting methods.
