FERROSILICON INOCULANT FOR INOCULATION OF CAST IRON,METHOD OF OBTAINING SUCH INOCULANT,METHOD OF INOCULATING CAST IRON BATH,AND GREY CAST IRON INOCULATED WITH SUCH INOCULANT

摘要

A silicon bearing strontium containing incoulant for cast or ductile iron is disclosed comprising zirconium, titanium or a mixture thereof. The inoculant may contain between 0.1 to 10% strontium, less than 0.35% calcium and either 0.1 to 15% zirconium, 0.1 to 20% titanium or a mixture of both zirconium and titanium with the strontium. The inoculant, method for produing the inoculant, method for inoculating the melt and an iron so inoculated are described.
