Products Description
The main components of ferrosilicon 75 are silicon and iron, of which the silicon content is usually between 72% and 75% (some say that ferrosilicon 75 is composed of 75% silicon and 25% iron, but the silicon content in the actual product may be slightly different). This high silicon content makes ferrosilicon 75 have unique application value in many industrial fields. Ferrosilicon 75 is made of coke (or semi-coke), steel scraps (iron oxide scale), and quartz (or silica) as raw materials, and is smelted at high temperature in an electric furnace. During the production process, the raw materials are melted and chemically reacted, and the silicon element is reduced and combined with iron to form a ferrosilicon 75 alloy.
Ferrosilicon 75 has high density, high strength, high toughness, good ductility and wear resistance. It is amorphous, has higher strength and toughness, can withstand various external pressures, and exhibits good impact resistance and corrosion resistance. In addition, Ferrosilicon 75 also has good magnetic conductivity.
Ferrosilicon 75 is an indispensable deoxidizer in the steelmaking process. In the final stage of steelmaking, adding ferrosilicon 75 to molten steel can effectively remove oxygen from the molten steel and improve the purity and quality of the steel. Through deoxidation, ferrosilicon 75 helps prevent defects such as bubbles and looseness in the steel during solidification, thereby improving the mechanical properties and processing properties of the steel. In the cast iron industry, ferrosilicon 75 is often used as an inoculant and spheroidizer. Adding ferrosilicon 75 can refine the graphite morphology in cast iron and make it more evenly distributed, thereby improving the strength and hardness of cast iron. At the same time, ferrosilicon 75 also helps to promote the precipitation and spheroidization of graphite and improve the organizational structure and properties of cast iron. Ferrosilicon 75 can be used as a reducing agent in ferroalloy production, especially in the production of low-carbon ferroalloys. Since ferrosilicon 75 has a very low carbon content, it is a relatively common reducing agent that can be used to reduce other metal oxides to prepare the desired ferroalloy. Ferrosilicon 75 can also be used to manufacture silicon steel sheets, which is an important soft magnetic material widely used in fields such as electricity, electronics and communications.
In summary, ferrosilicon 75 is widely used in steel smelting, cast iron production, ferroalloy manufacturing and many other fields. Its main functions are deoxidation, inoculation, spheroidization and as a reducing agent, which is of great significance to improving product quality and performance.
