Grades Of Ferro Silicon
The grade of ferro silicon is based on the elemental silicon content. The common ferro silicon grades are mainly ferro silicon 75, ferro silicon 72, and ferro silicon 65, they which are widely used in steel making, foundry, and metallurgical industries. It becomes important to select the correct grade of ferro silicon for the production of your product, as this has a direct impact on the purchase price and production costs.
Different Grades Of Ferro Silicon Content & Composition
The main chemical components in ferro silicon are Si, Fe, Al, Ca, Mn, CR, P, S and C. The raw material of ferrosilicon determines the silicon content, different grades of ferro silicon chemical composition content are different, where the higher silicon content of ferro silicon grade belongs to the high purity ferro silicon, whether in the sale price or in the use of the effect are slightly higher than other grades of ferro silicon.

Uses And Applications Of Different Grades Of Ferro Silicon
The correct grade should be selected according to the different applications of ferro silicon and fields of application. Ferro silicon for steel making requires a high Si content, ferro silicon can efficiently deoxidize the steel in the process of steelmaking, and has the purpose of improving the inclusions pattern in the steel and reducing oxides. Ferro silicon for casting requires low sulfur and low nitrogen, which effectively reduces the tendency of cast iron to develop a white mouth, promotes the effect of conception, and improves the distribution of graphite. In the field of metallurgy, ferro silicon is often used as a reducing agent, for example, in the production of some low-carbon ferroalloys, ferro silicon has a good reducing effect.
Classification And Implementation Standards Of Different Grades Of Ferro Silicon
According to the different production methods and implementation standards of different grades of ferro silicon, ferro silicon can be divided into high ferro silicon, normal ferro silicon, low aluminum ferro silicon, ferro silicon nitride, ferro silicon manganese, and high purity ferro silicon. High-purity ferro silicon is produced using the method of off-furnace refining to effectively process the impurity elements within it, which significantly improves the purity of ferro silicon. The thickness of the ferro silicon of FeSi72~FeSi75 series grades produced by the iron mold casting method is required to be no more than 100mm, and the thickness of ferro silicon of FeSi40, FeSi65, and FeSi70 grades is required to be no more than 80mm. ferro silicon that takes direct molding by casting has a deviation of Si content of no more than 3.0%.
