(1)Deoxidizer and alloy additive in steel making.
(2)Nucleating agent and nodulizer in cast iron industry.
(3)Reduceing agent in ferroalloy production.
Among the above purposes, steel making industry and cast industry are the biggest consumer of ferro silicon. And among the different steel grade of ferro silicon, 75% ferro silicon is the most popular right now. In steel making industry,3-5kg 75% ferro silicon is used for production 1 ton of steel.
Generally,72#,73#,74#,75# four kinds of ferro silicon is produced in China (steel grade is the silica percentage content in ferro silicon), among which 74#, 75# are exported more and 75# ferro silicon is used would wide.
