Ferro Silicon 75% & 72% Lump and Powder:
Product Description
Ferro Silicon is an atomised alloy, which is formed by combining iron and silicon with a silicon content range of 15% to 90%. Ferro Silicon is a universal "heat-blocker" used in the production of carbon and stainless steels.
Size: 10-100mm, 90%min
Packing: In 1 MT big bag with bottom spout.
Chemical composition and size above can be optimized according to custom's requirement.
Detailed application:
1. Ferrosilicon is often used as deoxidizer in steel- making.
2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
3. Ferrosilicon commonly used as a reductant in ferroalloy production and chemical industry.
4. In iron industry it often used as inoculant and nodulizer and deoxidize.
