Details of use of ferrosilicon powder

Ferrosilicon powder is composed of iron and silicon ferroalloy, and then after grinding into powder material, used for steelmaking, iron deoxidizer, can also be used as the raw materials of hydrogen. Ferrosilicon powder model: with the common model of ferrosilicon, mainly 75#, 72#, 70#, 65#, 60#; Common granularity: 60 mesh, 80 mesh, 200 mesh, 0-1mm, 0-3mm, or according to customer requirements; Packing using tons of packaging (1000kg/ package), 25kg child mother bag or according to customer requirements customized;

The main uses of ferrosilicon powder are as follows:

(1) used as deoxidizer and alloying agent in steelmaking production. Adding a certain amount of silicon in the steel can significantly improve the strength, hardness and elasticity of the steel, so in the smelting of structural steel (containing silicon 0.40-1.75%), tool steel (containing Sio.30-1.8%), spring steel (containing Sio.40-2.8%) and silicon steel for transformer (containing silicon 2.81-4.8%), Ferrosilicon is also used as an alloying agent.

(2) used as inoculant and spheroidizing agent in cast iron production. Cast iron is an important metal material in modern industry. It has excellent casting properties and much better aseismic ability than steel. Especially nodular cast iron, adding a certain amount of ferrosilicon in cast iron can prevent the formation of carbide in iron, promote the precipitation of graphite and spheroidization, so in the production of nodular cast iron, ferrosilicon is an important inoculant (to help the precipitation of graphite) and spheroidizing agent.

(3) used as reducing agent in ferroalloy production. Not only is the chemical affinity between silicon and oxygen great, but the carbon content of high silicon ferrosilicon is very low. Therefore, high silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low carbon ferroalloy in the ferroalloy industry.
