FeSi75AL1.5 ferrosilicon alloy

Quick Details

Use:
in addition, in the steel industry, the use of ferrosilicon powder burn at high temperatures can release a large amount of heat the characteristics of en, often as ingot heating agent cap is used to improve the quality of ingot and recovery rate.
(2) and the ball used as inoculant agent in the iron industry. Cast iron is one of the important metal materials in modern industry, it is cheaper than steel, it is easy to melt and smelt, has excellent casting properties and is much better than steel. In particular, the mechanical properties of nodular cast iron and its mechanical properties are close to or close to that of the steel. In cast iron added a certain amount of ferrosilicon can prevent the formation of iron carbide and promote the precipitation of graphite and the ball, so in the production of ductile iron, ferrosilicon is a kind of important inoculant (help graphite precipitation) and spheroidizing agent.
(3) is used as a reducing agent in the production of iron alloy. Not only silicon and oxygen chemical affinity between the large and high carbon silicon ferrosilicon is very low. High silicon ferrosilicon (or silicon alloy) is the production of low carbon ferroalloy ferroalloy industry is more commonly used as a reducing agent. grades of chemical composition < br / > Si Al CA Mn CR P S C < br / > range is not greater than < br / > FeSi75AI1.0-b 72.0-80.0 1 1 0.5 0.5 0.04 0.02 0.2 < br / > FeSi75AI1.5-b 72.0-80.0 1.5 0.5 0.5 0.04 0.02 0.2 < br / > ferrosilicon in steel industry, foundry industry and other industrial production has been widely used.
ferrosilicon is steelmaking industry indispensable deoxidizer. JUGANG, ferrosilicon for sedimentation and diffusion deoxidation. Brick iron as alloy agent used in steelmaking. Adding a certain amount of silicon, can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, reduce the hysteresis loss of the transformer steel. General steel containing silicon 0.15%-0.35%, structural steel containing silicon 0.40% to 1.75%, tool steel containing silicon 0.30% ~ 1.80% and spring steel containing silicon 0.40% ~ 2.80%, acid resistant stainless steel containing silicon 3.40% to 4.00%, heat-resistant steel containing silicon 1.00% to 3.00%, silicon steel containing 2% ~ 3% silicon or higher.
high silicon ferrosilicon or silicon alloy as the reducing agent in the production of low carbon iron alloy in ferroalloy industry. Ferrosilicon added cast ductile iron inoculant, and can prevent the formation of carbides and promote the precipitation of graphite and spheroidizing and improve performance of cast iron. < br / > in addition, silicon iron powder in the mineral processing industry can be suspended phase of using, in the coating of electrode welding manufacturing; high silicon ferrosilicon in the electrical industry can be used for preparing pure semiconductor silicon, and can be used in the chemical industry in the manufacture of silicone.
in steelmaking industry, each producing a ton of steel consumption of about 3 ~ 5kg75% ferrosilicon.
