Influence of inoculation on shrinkage defects in

2012-5-3 · AbstractDefective castings produce unnecessary costs for foundries. Common flaws in spheroidal graphite cast iron castings are shrinkage defects. The literature on the subject suggests that by controlling the precipitation of graphite, it is possible to suppress the shrinkage propensity of the melt. The most influential way of affecting the precipitation of graphite is inoculation.
