Shrinkage defect in an alloy steel casting for marine engine cylinder cover
was estimated by numerical analysis with reference to casting variables
such as riser and chiller. Retained melt modulus was employed as a
prediction parameter in this study. Shrinkage defects were developed at
the final solidification region. This is associated with hot spots, which could
be controlled more effectively by adjusting the height of riser and by
attaching chiller to the casting outside. Based on the numerical analysis,
sound castings were produced successfully and economically.
