Description
Ferrosilicon
Ferrosilicon is coke, steel scrap, quartz (or silica) as raw
material, made by smelting. Silicon and oxygen easily synthetic
silica. So ferrosilicon often used for steelmaking deoxidizer, at
the same time as SiO, generating a lot of heat release, in oxygen
at the same time, can improve the temperature of molten steel in
steelmaking energy consumption reduced. Ferrosilicon as alloy
additives, widely used in low alloy structural steel, alloy
structural steel, spring steel, bearing steel, heat - resistant
steel and electrical steel. Ferrosilicon in ferroalloy production
and chemical industry, also used as reducing agent. Pure silicon
silicon content up to *5%**9%, used to manufacture silicon or
preparation of non-ferrous metal alloy.
Use:
Ferrosilicon is widely used in foundry industry and other
industrial production, steel industry.
Ferrosilicon is steelmaking industry indispensable deoxidizer.
Steelmaking, ferrosilicon used sedimentation and diffusion
deoxidation. Silicon as an alloying agent for steelmaking. Add a
certain amount of silicon steel, high strength of steel, can
significantly improve the steel hardness and elasticity,
permeability, transformer steel lower hysteresis loss. General
steel containing silicon 0.*5%*0.*5%, structural steel containing
silicon 0.*0%*1.*5%, tool steel containing silicon O. *0%*1.*0%,
spring steel containing silicon 0.*0%*2.*0%, acid-resistant
stainless steel containing silicon 3.*0%*4.*0%, heat-resistant
steel containing silicon 1.*0%*3.*0%, silicon steel containing
silicon 2%*3% or higher. To promote the precipitation of carbide
formation, and the spheroidization of graphite, to improve the
performance of cast iron.
In addition, silicon powder can be suspended in the mineral
processing industry, as the electrode in the electrode
manufacturing coating: High silicon ferrosilicon in the electrical
industry can be used for the preparation of pure silicon
semiconductor, in the chemical industry can be used in the
manufacture of silicone.
