What is ferro silicon used for?
It is used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the later stages of steelmaking must be deoxidized, silicon and oxygen between the chemical affinity is very large, and thus ferrosilicon is a steel stronger deoxidizer for precipitation and diffusion deoxidization.
In addition, in the steelmaking industry, the use of ferrosilicon powder at high temperatures can release a lot of heat this feature, often used as ingot cap heating agent in order to improve the quality of steel ingots and recovery rate.
Add a certain amount of silicon in steel, can significantly improve the strength, hardness and elasticity of steel, and therefore in the smelting of structural steel (containing bracteate silicon 0.40-1.75%), tool steel (containing SiO.30-1.8%), spring steel (containing SiO.40-2.8%) and transformer with silicon steel (containing silicon 2.81-4.8%), but also ferrosilicon as an alloying agent to use.
In the cast iron industry as an inoculant and spheroidizing agent. Cast iron is an important metal material in modern industry, it is cheaper than steel, easy to melt and smelt, with excellent casting performance and much better than steel to engage in the ability to vibration, especially ductile iron, its mechanical properties to reach or close to the mechanical properties of steel.
Add a certain amount of ferrosilicon in cast iron can prevent the formation of carbides in iron, promote the precipitation of graphite and spheroidization, and thus in the production of ductile iron, ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizing agent.
Used as reducing agent in ferroalloy production. Not only is there a great chemical affinity between silicon and oxygen, but high silica ferrosilicon has a very low carbon content. Therefore, high silica ferrosilicon (or siliceous alloy) is a kind of reducing agent more commonly used in the production of low carbon ferroalloys in ferroalloy industry.
Uses in other aspects. Finely ground or atomized processed ferrosilicon powder can be used as a suspended phase in the mineral processing industry. It can be used as coating for welding rods in the welding rod manufacturing industry. Highly siliceous ferrosilicon is used in the chemical industry to manufacture products such as silicones.
Among these uses, the steelmaking industry, foundry industry and ferroalloy industry are the larger users of ferrosilicon. Together they consume about 90% or more of ferrosilicon. Among the different grades of ferrosilicon, the more widely used is 75% ferrosilicon. In the steelmaking industry, each production of 1t of steel consumes about 3-5kg of 75% ferrosilicon.
Ferrosilicon is widely used in the steel industry, foundry industry and other industrial production. Ferrosilicon is an essential deoxidizer in the steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. The addition of a certain amount of silicon in steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel and reduce the hysteresis loss of transformer steel. General steel containing silicon 0.15% -0.35%, structural steel containing silicon 0.40% ~ 1.75%, tool steel containing silicon 0.30% ~ 1.80%, spring steel containing silicon 0.40% ~ 2.80%, stainless and acid-resistant steel containing silicon 3.40% ~ 4.00%, heat-resistant steel containing silicon 1.00% ~ 3.00%, silicon steel containing silicon 2% ~ 3% or higher.
High silicon ferrosilicon or silicon alloy in the ferroalloy industry as the production of low-carbon ferroalloy reducing agent. Ferrosilicon added to cast iron can be used as ductile iron inoculant, and can prevent the formation of carbide, promote the precipitation of graphite and spheroidization, improve the performance of cast iron.
In addition, ferrosilicon powder in the mineral processing industry can be used as a suspended phase, in the welding rod manufacturing industry for the coating of welding rods; high silica iron in the electrical industry can be used to prepare semiconductor pure silicon, in the chemical industry can be used for the manufacture of silicone and so on. In the steel industry, every ton of steel production consumes about 3-5kg of 75% ferrosilicon.
