The main components of ferrosilicon powder are silicon and iron, of which the content of silicon is generally between 50% and 70%, and the content of iron is between 20% and 30%. Ferrosilicon powder also contains a small amount of aluminum, calcium, magnesium and other elements. The chemical properties of ferrosilicon powder are stable, not easy to oxidize, and can be preserved for a long time. The physical properties of ferrosilicon powder are also very good, with high temperature stability, high strength, high hardness and high wear resistance.The use of ferrosilicon powder is as follows:
(1)ferrosilicon powder is an important metallurgical raw material, widely used in casting, steel manufacturing, aluminum alloy manufacturing and other fields. Ferrosilicon powder can be used as a reducing agent to reduce oxides in metallurgical furnaces, thereby obtaining pure metals.
(2)ferrosilicon powder can also be used to prepare various casting alloys. In steel manufacturing, ferrosilicon powder can be used as a desulfurizer to remove sulfide in steel, thereby improving the quality of steel. In the manufacture of aluminum alloys, ferrosilicon powder can be used as an additive to improve the strength and hardness of aluminum alloys.
(3) ferrosilicon powder is also widely used in chemical and electronic fields. In the chemical industry, ferrosilicon powder can be used to produce organosilicone compounds, siloxanes and silanes. In the field of electronics, ferrosilicon powder can be used to prepare semiconductor materials, solar cells and so on.
