Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is coke, steel chips, quartz (or silica) as raw materials, with electric furnace smelting made of ferrosilicon alloy. Because silicon and oxygen are easy to combine into silicon dioxide, so iron silicon is often used as a deoxidizer in steelmaking. At the same time, due to the release of a lot of heat when SiO2 is generated, it is also favorable to improve the temperature of molten steel at the same time. At the same time, ferrosilicon can also be used as alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in ferroalloy production and chemical industry, commonly used as reducing agent.
Ferro silicon is widely used in the steel making, iron casting ,low-carbon ferro alloy producing:
In the steel making field, Ferro silicon is used as deoxidizer and alloying agent to precipit and diffuse deoxidation. Adding a certain amount silicon of Fe-Si to the steel can obviously improve the strength , hardness ,elasticity and permeability of steel.In the iron casting, it is used as ball mile agent and alloying agent especially in the nodular iron casting, Adding ferro silicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing. Then the mechanical capacity can be the same of steel's.
