Effect of Chemical Composition upon pinholes formation in Compacted graphite cast iron

Original language description

Purpose: This study concerns the formation of pinholes in castings by reaction between cast iron with compacted graphite and green sand mould. Methodology: Experiments were done on bar castings moulded in green bentonite mixtures without carbonaceous matters. Moulding sand moisture, aluminium and titanium content in the melt were purposely changed. Metal was melted in a 100 kg furnace by remelting the uniform charge of return material. Metal was inoculated all at once in a ladle and modified in a reaction chamber in a mould or as sandwich method in a pouring ladle. Findings: The formation of pinholes was caused not only by high moisture of the mould but this defect was sensible to aluminium content in metal. With Al content above 200 ppm there exists astrong probability of pinholes formation, and namely in practical terms without respect to moulding mixture moisture. But great difference between the pinholes amount when modifying cast iron in a mould and in a ladle has been found out.
