The present invention relates to an inoculant for the manufacture of cast iron with spheroidal graphite, said inoculant comprises a particulate ferrosilicon alloy consisting of between 40 and 80% by weight of Si
0.02-8% by weight of Ca
0-5% by weight of Sr
0-12% by weight of Ba
0-15% by weight of rare earth metal
0-5% by weight of Mg
0.05-5% by weight of Al
0-10% by weight of Mn
0-10% by weight of Ti
0-10% by weight of Zr
the balance being Fe and incidental impurities in the ordinary amount, wherein said inoculant additionally contains, by weight, based on the total weight of inoculant : 0.1 to 15% of particulate Bi2S3, and optionally between 0.1 and 15% of particulate Bi2O3, and/or between 0.1 and 15% of particulate Sb2O3, and/or between 0.1 and 15% of particulate Sb2S3, and/or between 0.1 and 5% of particulate Fe3O4, Fe2O3, FeO, or a mixture thereof, and/or between 0.1 and 5% of one or more of particulate FeS, FeS2, Fe3S4, or a mixture thereof, a method for producing such inoculant and use of such inoculant. |
