Abstract

Effects of simultaneous solidification and sequential solidification on quality of crankthrow shape parts were analyzed. The filling process of sequential solidification was simulated and compared with that from experimental results. The results show that the hot spot in crankthrow shape parts is effectively eliminated and the shrinkage porosity （hole） in the parts is decreased by controlling the sequence of solidification.
