High Silicon Ferrosilicon Block

 Used as inoculant and spheroidizing agent 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 properties and is much better than steel in earthquake resistance. In particular, the mechanical properties of ductile iron reach or are close to those of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in the iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizing agent. .

Used as reducing agent in ferroalloy production. Not only is the chemical affinity between silicon and oxygen very high, but the carbon content of high-silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or silicon alloy) is a commonly used reducing agent in the ferroalloy industry when producing low-carbon ferroalloys.
