摘要

An inoculant for the treatment of cast iron in the mould is made up of an inoculant alloy or mixture and possibly a binder. The inoculant alloy or mixture contains (by wt) 2.5 - 5% of aluminum, 0.3 - 8% of lanthanum and possibly up to 2% of calcium with the remainder being ferrosilicon. The inoculant may be obtained by casting the molten alloy (claimed) or by the agglomeration of a mixture or a powdered inoculant alloy (claimed).
