ferro silicon grains

Ferrosilicon particles referred to as silicon particles, that is, ferrosilicon inoculant, used in steelmaking, ironmaking, casting a inoculant.

Silicon grain characteristics:

(1) The composition of ferrosilicon particles is uniform and the segregation is small;

(2) Iron silicon particle size is uniform, no fine powder, stable inoculation effect;

(3) The inoculation effect of ferrosilicon particles is stronger than that of ordinary ferrosilicon, and the tendency to produce slag is also small;

(4) Extend die life and reduce surface defects;

(5) Reduce pinholes, improve the surface quality of the cast pipe, and improve the pass rate of the first inspection;

(6) Eliminate microporosity and improve the machining performance of castings.

The use of ferro silicon grains:

(1) Used as deoxidizer and alloying agent in steelmaking industry.

(2) Used as inoculant and nodulator in the cast iron industry. Cast iron is an important metal material in modern industry, it is cheaper than steel, easy to melt and smelt, has excellent casting performance and much better earthquake resistance than steel. In particular, ductile iron, its mechanical properties reach or approach the mechanical properties of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite, so in the production of ductile iron, ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizing agent.
