Description
Ferrosilicon grains is the small size of ferrosilicon, which is manufactured by machine as customer request. Ferro silicon is an iron-silicon alloy made from coke, steel scrap, and quartz(or silica),and smelted in an electric furnace.

Application
1. Deoxidizer and Alloying agent in Steelmaking industry:
1) Deoxidizer: Since silicon has a strong chemical affinity with oxygen, the related oxidizing reaction between silicon and oxygen could produce SiO2, so ferrosilicon is frequently used in steel making as deoxidizer. At the same time, when SiO2 is forming, it will release large amount of heat,which is beneficial to increase the temperature of the molten steel.
2) Alloying agent: When it’s used as alloying agent, it has a function of improving the strength, hardness and elasticity of steel, often used for smelting of structural steel (containing silicon 0.40-1.75%), tool steel (containing SiO.30-1.8%), spring steel (containing SiO.40-2.8%) and transformer silicon steel (containing silicon 2.81-4.8%).
2. Inoculant and Spheroidizing agent in cast iron industry.
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 in the production of ductile iron.
3. Reducing agent in ferro alloy production and chemical industry
High silicon ferrosilicon (or siliceous alloy) is a reducing agent commonly used in the ferroalloy industry to produce low carbon ferroalloys.
