Ferrosilicon inoculant is widely used in the casting process, especially for some products such as gray cast iron and ductile iron, ferrosilicon inoculant is an important furnace charge additive. Ferrosilicon inoculant is mainly used in electric furnaces, medium-frequency furnaces, and cupola furnaces. When using different kinds of furnaces, the charging method and time are different, and different charging methods are chosen according to the production process.

What Is Ferrosilicon Inoculant?

Ferrosilicon inoculant is rich in Si and trace elements such as Fe, Mn, Al, C, P, S. Ferrosilicon inoculant with low sulfur and low nitrogen is more suitable for casting and can significantly reduce the tendency of honeycomb holes and white mouth in castings. ferrosilicon inoculant with Si>75% is widely used in the casting process, mainly because high-purity silicon can better promote the number of eutectic spheres in the iron and effectively improve the inoculation effect of the iron. In the production process of ductile iron, it can improve the distribution morphology of graphite and enhance the graphite effect.

Usually, the appearance of ferrosilicon inoculant is mainly 10mm~50mm particles, and this appearance is easier to melt quickly after adding to the furnace, thus enhancing the use effect. Through calculations, we can come up with the ferrosilicon inoculant specifications that meet the casting process, and when using it, cooperate with stirring so as to enhance the melting speed and absorption rate of ferrosilicon inoculant.
