Low titanium (high purity) ferrosilicon
(1) Used as deoxidizer and alloying agent in the steelmaking industry. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In steelmaking production, except for some boiling steels, almost all steel types use ferrosilicon as a strong deoxidizer for precipitation deoxidation and diffusion deoxidation.
In addition, in the steelmaking industry, ferrosilicon powder can release a large amount of heat when burned at high temperatures and is often used as a heating agent for steel ingot caps to improve the quality and recovery rate of steel ingots.

(2) 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 much better earthquake resistance than steel. Especially ductile iron, its mechanical properties reach or are close to those of steel. performance. 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.
(3) 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.

(4) Use in other aspects. Ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as a coating for welding rods in the welding rod manufacturing industry. High-silicon ferrosilicon is used in the chemical industry to make products such as silicone.
