Effect of Preconditioning and Inoculation on Graphite …

This paper attempts to investigate the effect of preconditioning and inoculation on nodule count and their size distribution to eliminate shrinkage porosity in spheroidal graphite (SG) iron castings. Studies were conducted on various heats of SG iron prepared for differential case casting with and without the addition of 0.1% Al, Zr, Ca–FeSi alloy as preconditioner and Ca–Ce–FeSi alloy
