The main components of ferrosilicon 70 include silicon and iron, in which the content of silicon is usually about 70%, while the content of iron is about 20% to 25%. In addition to silicon and iron, ferrosilicon 70 may also contain some other impurity elements, such as manganese, chromium, molybdenum, nickel, vanadium, etc. The content of these elements is low, but it may have a certain impact on the properties of ferrosilicon.
To prepare ferrosilicon 70, silicon ore and iron ore are usually crushed and magnetically separated to adjust their composition ratio. Then, smelting is carried out in a blast furnace or an electric furnace, and the raw materials are heated to a high temperature, so they undergo a chemical reaction to form a ferrosilicon alloy. Finally, through the processes of cooling, solidification and crushing, the ferrosilicon alloy obtained by melting is prepared into the required block or powder products.
Ferrosilicon 70 plays a key role in iron and steel smelting. Because it contains a high proportion of silicon, ferrosilicon 70 can provide a melt with high silicon content, which is especially suitable for preparing special steels such as alloy steel and stainless steel. Ferrosilicon 70 can reduce the content of carbon and impurity elements in steel, and improve the purity and quality of steel. Ferrosilicon 70 can also reduce the melting point of steel, improve the smelting process and improve the quality and performance of steel products.
As a common raw material of ferroalloy, ferrosilicon 70 plays an important role in the ferroalloy smelting industry. It can be used to prepare ferrosilicon alloy, glass ferroalloy, ferrochromium alloy, etc. These ferroalloys are widely used in different fields. Ferrosilicon alloy is often used as a deoxidizer and alloy additive, which can improve the quality and variety of steel.
