Ferrosilicon alloy is an important metallurgical material composed of two main elements: silicon and iron. Its chemical formula is FeSi. The silicon content of ferrosilicon is between 15% and 90%, while the iron content is between 10% and 85%.In addition, ferrosilicon also contains a small amount of impurity elements such as manganese (Mn), chromium (Cr), phosphorus (P), and sulfur (S). The content of these impurities is strictly limited in different grades of ferrosilicon.

Ferrosilicon production mainly adopts the electric furnace reduction method. Silica, coke, and iron filings are added to the electric furnace in a certain proportion, and the electrodes are energized to generate high temperatures, causing a reduction reaction in the furnace. At high temperatures, the carbon in the coke reduces the silicon dioxide in the silica to silicon, and combines with iron to form ferrosilicon alloy. During the reaction process, the quality and proportion of the raw materials, as well as the temperature and current in the furnace, need to be strictly controlled to ensure the quality and performance of the product.

The ferrosilicon contents frequently purchased in the market include: FerroSilicon 75, FerroSilicon 72, FerroSilicon 70, FerroSilicon 65;

Size: 0-3mm, 3-10mm, 10-60mm, 10-100mm, etc.

Ferrosilicon form

Ferro Silicon Lump

Lumpy ferrosilicon usually includes natural ferrosilicon lumps and processed ferrosilicon lumps. The demand for ferrosilicon of 10-60mm is the largest, and the size can also be customized according to customer needs.

Ferro Silicon Granule

Granular ferrosilicon is obtained by processing ferrosilicon lumps. The size is usually in the range of 1-3mm, 3-10mm, etc. It can be customized according to needs.

Ferro Silicon Powder

Ferrosilicon powder is obtained after pulverization. The size of ferrosilicon powder is usually 320 mesh, 200 mesh, 60 mesh, 0.2mm, etc. Ferrosilicon powder can be deoxidized quickly, shortening the deoxidation time and reducing energy consumption.

Ferro Silicon Briquettes

Ferrosilicon briquettes are byproducts produced during the production of ferrosilicon alloys, which are processed, collected and pressed. The emergence of ferrosilicon briquettes reduces steelmaking costs, improves deoxidation rates, and can quickly adjust trace iron elements in molten steel.

Application Of FerroSilicon

Ferrosilicon alloys are widely used in the metallurgical industry

Because ferrosilicon alloys have excellent reduction properties and heat resistance, they are often used as deoxidizers and alloy additives in casting and smelting processes. During the casting process, ferrosilicon alloy can effectively absorb and combine oxygen, reduce the oxide content in molten iron, and improve the mechanical properties and surface quality of castings. In addition, ferrosilicon alloys can be added to different kinds of alloys to adjust their chemical composition and improve the properties of the alloys.

Ferrosilicon alloys are also widely used in the machinery industry

Due to its good ductility and toughness, ferrosilicon alloy is often made into castings, bolts and parts of various shapes and specifications for the manufacture and maintenance of mechanical equipment. Ferrosilicon alloy not only has good mechanical properties, but also has a low thermal expansion coefficient and high wear resistance, and can maintain stable performance under high temperatures and harsh environments. Therefore, ferrosilicon alloys are widely used in machinery and equipment in aerospace, automobile manufacturing, petrochemical and other fields

Ferrosilicon alloys also occupy an important position in the electronics industry

Because ferrosilicon alloys have good electrical conductivity and magnetism, they are often used in the manufacture of electronic components and electromagnetic equipment. For example, ferrosilicon alloys can be used to make the cores of transformers and inductors to improve the efficiency and performance of electromagnetic devices. At the same time, ferrosilicon alloys can also be made into sheet materials with bidirectional conductivity for the production of motors and generators. These electronic devices are not only efficient and energy-saving, but also widely used in the fields of information technology and communications.
