Ferro Silicon : Silicon Iron Alloy, Having A Silicon Content Of Between 40 And 90%; Typically Contains A Large Amount Of Iron Silicas And 1-2% Calcium. Ferrosiliconand Aluminum. Obtaining : - By Reducing The Silicon Dioxide (sio2, Natural Mineral = Quartz) At High Temperatures In Electric Furnaces. Use : - In The Production Of Alloyed Steels, Silicon Content Ensuring Good Deoxidation, As Well As Preventing The Decarburization Of Molten Steel; - Added To Gray Cast Iron, Increases Fluidity In Molten State. Chemical Composition : Si 72 ÷ 80%; Al = 1.5-2.0% Max; P = 0.05% Max; S = 0.04% Max; C = 0.20% Max. Granulation : 10 ÷ 50mm; 10 ÷ 80mm; 10 ÷ 100mm; (90% Min). Packaging : Big Bags 1.000 Kg.
