It is generally supplierd with the type of FeSi 75,72,70,65 etc in the size of 10-50mm packing in the 1ton jumbo bags or jumbo bags with wooden pallet. Specification: FeSi 75-A: Si 75%Min,Al 1.5%Max,C 0.2%Max,S 0.02%Max,P 0.04%Max FeSi 75-B:Si 75%Min,Al 2.0%Max,C 0.2%Max,S 0.02%Max,P 0.04%Max Its apperance color is bright grey,the density is small, The smaller the silicon content, the higher the proportion . According to the content of silicon , this product can be divided into industrial FeSi and the ferro silicon with the Si content 75%,72%,65%. Function-ferro silicon: 1. Ferro silicon often used as deoxidizer in steelmaking. 2. Ferro silicon alloy can as one type of ferroalloy can be used as alloy elements join agent, widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel. 3. FeSi is used as a reductant in ferro alloy(SiMn) production and chemical industry. 4. In iron industry, Ferro silicon briquette 75 can be used as inoculant and nodulizer.
