What is ferrosilicon used for?

Ferrosilicon occupies a relatively important place in ferroalloy products and is used in relatively large quantities in steelmaking and casting. What is the specific use of ferrosilicon? The following ferrosilicon manufacturer will help you understand the use of ferrosilicon in detail.

Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is made of coke, steel chips, quartz (or silica) as raw materials, and then it is melted in an electric furnace. When refining ferrosilicon traditionally, silicon is reduced from silica containing SIO2. Most of the smelting of ferrosilicon uses metallurgical coke as the reducing agent, and steel scraps are the regulator of ferrosilicon.In the steelmaking industry, approximately 3 to 5 kg of ferrosilicon is consumed for each ton of steel produced, accounting for 75% of the total:

(1) Ferrosilicon is an essential deoxidizer in the steel industry. In the steel industry, ferrosilicate is used for precipitation deoxidation and diffusion deoxidation. Iron brick is also used as an alloying agent in the steel industry.

(2) Ferro silicon Used as an inoculant and spheroidizer in the cast iron industry. In the production of ductile iron, ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizer.

(3)Ferrosilicon is used as a reducing agent in the production of ferroalloys. Not only is the chemical affinity between silicon and oxygen large, but the carbon content of ferrosilicon with high silicon content is very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.

(4) Ferrosilicon 75 is often used in the high temperature smelting process of magnesium, replacing magnesium in CaO.MgO, each ton of magnesium will consume about 1.2 tons of ferrosilicon, which plays an important role in magnesium production.

（5）In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry and as a coating for welding rods in the welding rod manufacturing industry; high-silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon and in the chemical industry to manufacture silicone, etc.

Here are some uses of ferrosilicon introduced in detail by Anyang Zhengzhao, I hope you find them useful! Therefore, many large steel mills need to purchase ferrosilicon for steelmaking. We have many cooperative customers at home and abroad, and we can supply high quality ferrosilicon with different specifications and particle size at favourable price.
