Si-Mn Si-Mn alloy: (1) the concept of: Si-Mn alloy by manganese, silicon, iron and a small amount of carbon and other elements of the alloy, is a broader purpose, the output of ferroalloy larger. Si-Mn alloy is commonly used in composite steel Deoxidizer, but also the production of low-carbon ferromanganese and electricity production of silicon manganese heat the reducing agent. Si-Mn alloy can be large, medium and small to take continuous submerged arc furnace for smelting operations. (2) Si-Mn more at home in southwest Yunnan, Guizhou, Guangxi, Hunan. Production of raw materials there Silicon manganese alloys, manganese-rich slag, silica, coke and so on. (3) common grade: FeMn68Si18 FeMn65Si17 FeMn60Si14 (4) material: manganese ore, manganese-rich slag, coke, silica, lime and so on. 1, the use of Si-Mn alloy: Si-Mn alloy of iron and steel production as Deoxidizer intermediate agents and alloy materials, but also low-carbon ferromanganese in the main raw material for production 2, Si-Mn alloy production methods: Si-Mn alloys are used in submerged arc furnace at the same time reducing carbon manganese ore (including the manganese-rich slag) and manganese oxide in silica and silica production and refining. 3, Si-Mn Alloys: Block, there are silver sheen, the proportion of 6.0-6.4.
