what is silica fume?

Silica fume is also called micro-silica fume or agglomerated silica fume. When iron alloy is smelting ferrosilicon and industrial silicon (metal silicon), a large amount of highly volatile SiO2 and Si gas is produced in the submerged thermal electric furnace.

Ferrosilicon spot, factory direct supply

High-silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low-carbon ferroalloys. Ferrosilicon added to cast iron can be used as an inoculant for ductile iron, which can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the properties of cast iron.

Influence of ferro silicon on steelmaking

Silicon is the raw material of smelting ferrosilicate, ferrosilicate suppliers believe that generally with high ferrosilicate rolling, in the process of electric furnace steelmaking, with ferrosilicate powder diffusion deoxidation.Whether the particle size of ferrosilicon powder is too fine or too coarse, will affect the synthesis of ferrosilicon nitride

ferro silicon process

ferro silicon is a strong deoxidization in steelmaking oxygen agents are used for precipitation and diffusion deoxidation.Adding a certain amount of silicon to steel can obviously improve the strength, hardness and elasticity of steel.So in the smelting of structural steel (including silicon 040-1.75%), tool steel (including SiO301.896), spring steel (including sio40-28%).And when transformer USES silicon steel (contain silicon 281-48%0), also USES ferrosilicon as alloying agent.

Henan star metallurgy mainly supplies 75 ferrosilicon, 72# ferrosilicon, 65# ferrosilicon, 45# ferrosilicon, four grades, ferrosilicon quality assurance, timely supply, according to customer requirements to provide natural block, standard block, particle, powder and other processing particle size.

Learn about silicon metal and ferro silicon from the production process

Many people are confused about metal silicon and ferrosilicon. In fact, ferrosilicon is a form of metallic silicon. Ferrosilicon is obtained by smelting metal silicon and iron. In order to solve this confusion for everyone, here we will focus on the two from the production process.
