Industrial Ferro Alloy Off Grade Silicon Silicon Metal Alternative Ferro Slag
1. Silicon slag(off grade silicon) is a by-product when making silicon metal.
2. The silicon content is from 45% to95%, and the rest are C, S, P, Al, SiO2, Fe, Ca etc.
3. The silicon slag is much cheaper than purity silicon metal, and has many industrial applications.
Application
1. Silicon content from 30~50% is used for silicon addition for iron making in the blast furnace and cupola, 50~70% is used for the deoxidization of steel making.
2. Silicon Slag can used as Silicon metal alternative.
3. We use silicon slag to produce silicon briquette which is far and wide market in domestic and international.
4. Silicon slag is a good substitute of FeSi in steel making, which has advantage in reducing the cost of production.
