Silicon II

Used as inoculants in the iron industry and nodulizer. Cast iron is one of the most important metal in modern industry, it's cheaper than steel, easy to melt melting and excellent casting performance and much better than steel seismic capacity. Particularly ductile iron, its mechanical properties are at or close to the mechanical properties of steel. In cast iron, formed by adding a certain amount of Silicon can prevent iron carbide, promote the precipitation of graphite and balls, and in the production of spheroidal graphite cast iron, ferrosilicon is a vital Inoculants (helped precipitated graphite) and nodulizer.
