Introduction:ferro silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro silicon used coke, quartz (or silica) as raw material and using electric furnace to made by. Because of silicon and oxygen are easily compound into sio2, so the ferrosilicon often used as deoxidizer in steelmaking.
Properties: 1.supply ferro silicon alloy is used to precipitate and diffuse deoxidation in steel making. We add a certain volume of silicon to steel to improve the strength, hardness and flexibility of steel.
2.ferro silicon alloy also improves permeability of steel and lowers hysteresis loss of transformer steel obviously. It is an important type of inoculation and nodulizer in the process of spheroidal graphite cast iron making.
3:silicon briquiette is a good subsitute for fesi in steel making,which has advantage in lowing the cost of production and reusing resource.this product is new product we developed and mainly repressed by silicon powder.now there are far and wide market in domestic and oversea market.
