Specifications of ferrosilicon

Date: 01-18-2024
Ferrosilicon is an important iron alloy that is widely used in steel smelting, casting and other fields. Its main components are silicon and iron, and also contains small amounts of carbon, manganese, sulfur, phosphorus, etc.

element. The specifications and models of ferrosilicon are as follows:

Specification model Silicon content (%) Iron content (%) Carbon content (%) Manganese content (%) Sulfur content (%) Phosphorus content (%)

75# 74.0-80.0 Margin ≤24.0 ≤0.04 ≤0.4 ≤0.02 ≤0.04

72#72.0-78.0 margin≤25.0 ≤0.04 ≤0.4≤0.02≤0.04

70# 70.0-76.0 margin ≤26.0 ≤0.04 ≤0.5 ≤0.02≤0.04

65# 65.0-72.0 Margin ≤30.0 ≤0.04 ≤0.5 ≤0.02≤0.04

The main use of ferrosilicon is as a deoxidizer and alloy additive in steel smelting. During the steel smelting process, adding an appropriate amount of ferrosilicon can reduce the oxygen content in the steel and improve the purity and strength of the steel. At the same time, the silicon in ferrosilicon can also form alloys with other elements in steel to improve the physical and chemical properties of steel, such as improving wear resistance, corrosion resistance, tensile strength, etc.

Ferrosilicon is also widely used in casting fields. During the casting process, ferrosilicon can be used as a deoxidizer and alloy additive to improve the structure and properties of castings, such as reducing defects such as pores, inclusions and shrinkage cavities, and improving the strength and toughness of castings. At the same time, ferrosilicon can also be used as a raw material for refractory materials to make high-temperature furnace materials and refractory bricks.

According to different uses and requirements, the specifications and models of ferrosilicon are also different. For example, in steel smelting, ferrosilicon is required to have high silicon content and low iron content; while in casting, ferrosilicon is required to have both silicon content and iron content within a certain range. Therefore, when selecting the specifications and models of ferrosilicon, you need to choose according to actual needs to achieve the best results.

Ferrosilicon is an important iron alloy with wide application prospects. By selecting appropriate specifications and models, the needs of different fields can be met and the quality and performance of products can be improved.
