Ферро кремния

Application:Ferro Siliconis used to precipitate and diffuse deoxidation in steel making.Properties: We add a certain volume of silicon to steel to improve the strength, hardness and flexibility of steel.Ferro Silicon also improves permeability of steel and lowers hysteresis loss of transformer steel obviously.Ferro Silicon is an important type of inoculation and nodulizer in the process of spheroidal graphite cast iron making.Chemical Compositions(GB/T2272-1987)BrandChemical Compositions (%)SiAlCaMnCrPSC≤FeSi75-A74.0 80.0--------0.40.30.0350.020.1FeSi75-B74.0 80.0--------0.40.30.040.020.1FeSi75-C72.0 80.0--------0.50.50.040.020.2FeSi6565.0 <72.0--------0.60.50.040.02----FeSi4540.0 <47.0--------0.70.50.040.02---- 4.Package:1Metric Ton per big bag(polypropylene knitted bag).
