Ferrosilicon in the steel and casting industries

It is widely used in other industrial production.

Ferrosilicon is an essential deoxidizer in the steelmaking industry

In torch steel, silicon iron is used for precipitation deoxidation and diffusion deoxidation. Brick cast iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve its strength, hardness, and elasticity, increase its magnetic permeability, and reduce the hysteresis loss of transformer steel

General steel contains 0.15% -0.35% silicon

Structural steel contains 0.40% to 1.75% silicon, tool steel contains 0.30% to 1.80% silicon, spring steel contains 0.40% to 2.80% silicon, stainless acid resistant steel contains 3.40% to 4.00% silicon, heat-resistant steel contains 1.00% to 3.00% silicon, silicon steel contains 2% to 3% silicon or higher

High silicon ferrosilicon or siliceous alloys

Used as a reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry. Adding silicon iron to cast iron can serve as an inoculant for ductile iron, prevent the formation of carbides, promote graphite precipitation and spheroidization, and improve the properties of cast iron

Silicon iron powder can be used as a suspended phase in the mineral processing industry

Used as a coating for welding rods in the welding rod manufacturing industry; High silicon ferrosilicon can be used in the electrical industry to prepare semiconductor pure silicon, and in the chemical industry to manufacture silicones and other materials.

Introduction to Ferrosilicon

Ferrosilicon is an iron alloy composed of elements such as iron, silicon, and carbon. The main body of ferrosilicon products is FeSi, with a Si content between 70% and 80%. Ferrosilicon is usually divided into different specifications such as ferrosilicon 72, ferrosilicon 75, and ferrosilicon 65, where the number represents the Si content.

The Si content of ferrosilicon

The Si content of ferrosilicon varies among different specifications. The Si content of ferrosilicon 72 is about 72%, the Si content of ferrosilicon 75 is about 75%, and the Si content of ferrosilicon 65 is about 65%. The Si content of ferrosilicon has a certain impact on its properties and applications.

Production of ferrosilicon

The production of ferrosilicon adopts the method of graphite electrode arc furnace smelting, and there are differences in production between blast furnaces and electric furnaces. The quality of silicon iron produced in blast furnaces is poor, with low Si content, but the production cost is relatively low; The silicon iron produced in electric furnaces has better quality and higher Si content, but the production cost is higher

The use of ferrosilicon

Ferrosilicon is widely used in industries such as steel, casting, and metallurgy. In the steel industry, ferrosilicon is an important alloy additive that can improve the strength, toughness, and wear resistance of steel. In the casting industry, ferrosilicon is used to manufacture alloy castings. In the metallurgical industry, ferrosilicon is used to reduce metals
