the applications of ferro silicon

Ferro Silicon is smelted in electric furnace with the raw material of coke, steel scrap and quartz. The general types of ferro silicon are 75#,72# and 65# and others.


Ferro silicon is widely used in the steel industry, foundry industry and other industry production. 

Firstly, As the alloy additive, adding a certain amount of silicon into the steel, can improve the strength, hardness and elasticity of steel obviously, can also improve the permeability of steel, reduce the hysteresis loss of transformer steel. It is widely used in low alloy structural steel, alloy steel, spring steel, bearing steel, heat-resistance steel and electrical silicon steel. The generally steel contains 0.15%~0.35% silicon; The structure steel contains 0.40%~1.75% silicon; The tool steel contains 0.30~1.80% silicon; The spring steel contains 0.40~2.80% silicon; the heat resistant steel contains 1.00%~3.00% silicon; the silicon steel contains 2.00%~3.00% silicon or much higher; the stainless and acid-resistance steel contains 3.40%~4.00% silicon.

Secondly, Adding the ferro silicon into cast iron, it can be the inoculant for the ductile cast iron, the general using type is 75# ferro silicon. It can promote graphitization and reduce the tendency of white mouse, can improve graphite morphology and distribution, increase the number of eutectic groups, refine the basic organization, and can prevent to form the carbide.

Thirdly, Often be used as deoxidizer in steel making for precipitation deoxidation and diffusion deoxidation. Because of flowing up a lot of heat when it come to be silica, when deoxidization, it can increase the temperature of  molten steel and decrease the energy consumption in steel making.

Except the above applications, the pure silicon with silicon content reached 95%-99%, is commonly used to produce the monocrystalline silicon or to make the non-ferrous metal alloy; the ferro silicon powder is to be used for suspension in the mineral processing industry and as coatings for welding rods in production of welding rod; the high silicon ferro silicon can be used to make the semiconductor pure silicon and to make the silicone.
