1. Ferrosilicon is a ferrosilicon alloy composed of silicon and iron in a certain proportion, mainly used in iron and steel smelting and metal Magnesium smelting.
2. Adding ferrosilicon in steelmaking will cause deoxidation reaction: 2Fe0+Si=2Fe+Si02, thus removing the oxygen can improve the quality of steel, such as the strength, hardness and elasticity of steel, and improve the magnetic permeability of steel.
3. In magnesium smelting, 75# ferrosilicon and other production raw materials are reduced to
Magnesium is replaced and reduced to crude magnesium. The reaction process is: 2MgO+S i=2Mg+S i02
4. Chemical composition of ferrosilicon: Si Fe Al Ca P S C
5. Physical properties of ferrosilicon:
Melting point: 72#- -80# ferrosilicon melting point 1290°C-1360°C, 75# ferrosilicon melting point 1300°C
6. The density of ferrosilicon depends on the silicon content of ferrosilicon, and its density increases with the increase of silicon content in the alloy.
Reduced, 75# ferrosilicon density 3270Kg/m3.
7. Reasons for ferrosilicon pulverization.
The pouring thickness of ferrosilicon requires that the ferrosilicon ingots of all grades of FeS i75 series shall not exceed 100 mm.
