| 简介 |
The present invention relates to inoculant for the manufacture of cast iron with lamellar, compacted or spheroidal graphite. The inoculant comprises a particulate ferrosilicon alloy comprising between about 40 to 80 wt% silicon, between about 0.1 to 10 wt% calcium, between 0 and 10 % by weight of rare earths, for example cerium and/or lanthanum, and up to 5 wt% aluminium the balance being ironand incidental impurities in the ordinary amount, wherein said inoculant additionally comprises 0.1 to 10 wt%, based on the total weight of inoculant, antimony oxide where said antimony oxide is in particulateform and is mixed or blended with the ferrosilicon alloy particles, or is simultaneously added to cast iron together with the particulate ferrosilicon alloy particles. The invention further relates to a method for the production of the inoculant. |
