Silicon iron is commonly known as Ferrosilicon. Ferrosilicon’s many useful properties are its high specific gravity, magnetism, abrasion, and corrosion resistance. The density and melting point of ferrosilicon is affected by the amount of silicon it contains, and it is relatively cheap.  The density of Ferrosilicon also changes with alloy composition ratios. For the highest quality ferrosilicon alloys, go no further than OUSHI Metal, one of the world’s leading suppliers. Read on for more about silicon iron.


What is Silicon Iron?


Ferrosilicon (FeSi) is an iron and silicon alloy that plays an important role in steelmaking, both as an alloying component and for deoxidization. It is added in trace amounts to modify the melt and cooling process and the final product’s properties.

In addition to preventing carbon loss, FeSi has a deoxidizing effect. In addition, ferrosilicon is used to manufacture silicon, hydrogen, and magnesium electrode coatings.


How is ferrosilicon Produced?


The most common form of ferrosilicon, known as “FeSi75,” contains 75% silicon by weight, but other forms can have anywhere from 15% to 90% silicon by weight. When iron is added to a reduction of silica, sand, and coke, ferrosilicon is created, which chemical manufacturers in either a blast furnace or an electric arc furnace based on silicon content. After they pour it from the furnace, the molten material cools into a thin, flat sheet.

The sheet is crushed using the proper machinery after it has cooled, and the results are processed further. The resulting particles can be as small as dust or as large as chunks several centimeters in length. For further processing, the FeSi is separated into various particle sizes.


Silicon Iron Applications


One of the ways how Ferrosilicon is used is by combining it with water in a cyclone to create a pulp with a particular density. Diamonds and iron, among other minerals, can be efficiently separated from materials thanks to the cyclone. It helps to push heavier material to the bottom while lighter material floats. Uses for ferrosilicon include;

  • Cast iron manufacturing: Ferrosilicon is used to inoculate the iron to accelerate graphitization. Cast iron is a key metal material in the metal industry because it is less expensive than steel, easier to melt and smelt, and has outstanding casting performance. It is much better than steel when it comes to seismic capacity, particularly ductile iron, which has mechanical properties comparable to steel. Manufacturers can prevent cast iron carbide formation and improve graphite precipitation by adding a small amount of ferrosilicon. Thus, ferrosilicon is a crucial inoculant in the creation of ductile iron.
  • Deoxidizing Steel: Ferrosilicon is useful in steelmaking to deoxidize steel and other ferrous alloys. As a result, less carbon is lost when the steel is molten.
  • Arc-Welding: Ferrosilicon is frequently used in arc welding for electrode coating.
  • Heavy media separation: There are many applications for ferrosilicon in the metalworking sector, including atomization, melting, and media separation processes.
  • Fuel: To save fuel costs, some steel plants put ferrosilicon into the melt and burn it off to heat the furnace.
  • The Pidgeon process is the silicon thermal technique for producing magnesium metal.


What are the Necessary Precautions While Handling Ferrosilicon?


As an irritant, a toxin, and a fire hazard, ferrosilicon is a chemical to be avoided. As a result of its composition, the alloy poses a threat to human health. When this alloy comes into contact with water, bases, or acids, it produces toxic and flammable vapors. Thus, proper precautions must be taken to prevent the material’s accidental ingestion or inhalation.

You should wear eye and skin protection while handling this alloy since ferrosilicon has a high degree of consistency. This substance can catch fire under some conditions, so proper safety precautions must be taken whenever this material is exposed.

While deciding on the best grade of Ferrosilicon for your needs, there are a few things to bear in mind. You should consider factors such as the medium’s viscosity, stability, and density. This will ensure you receive the highest quality Ferrosilicon material for your specific application.

We will take the time to learn about your product’s needs, then figure out the ferrosilicon standard that will provide you with the highest quality at the lowest possible cost, all while providing you with expert help and insight throughout the manufacturing process.
