Abstract

Self-developed shrinking eliminating agent for alloy crankshaft was used to crankshaft specimen with dispersed shrinkage , changing the package materials, the composition and the amount of addition of the shrinking eliminating agent, macroscopical and microcosmic analyses of the section were performed to optimize the effect with the comparison. The results show that the better package material is the gray cast iron which melts completely in molten iron during casting. When the addition of eliminating shrinking agent No.3 is 6 g, the shrinkage defects of crankshaft specimen can be eliminated completely. After adding shrinking eliminating agent, no abnormal graphite appears, the amount of spheroidal graphite increases and the sphere diameter reduces.
