Ferrosilicon is an iron alloy made of iron and silicon. Because silicon and oxygen can easily combine to form silicon dioxide, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, since a large amount of heat is released when silicon dioxide bricks are generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. Ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, bearing steel, spring steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry.
Difference and connection between inoculant and ferrosilicon:
In the cast iron industry, ferrosilicon is generally used as an inoculant and spheroidizer. Cast iron is an important metal material in modern industry. It is cheaper than steel, easier to melt and smelt, and has excellent casting properties. Cast iron is also much better in earthquake resistance than steel. In particular, ductile iron has mechanical properties that can reach or approach those of steel. Therefore, in ductile iron production, ferrosilicon is an important inoculant and spheroidizer. It can be seen from this that there is not much difference between the two, and both are used as inoculants in cast iron.
