Ferrosilicon Manganese:
Ferrosilicon manganese is a type of ferroalloy that contains 60 to 68 percent manganese, 14 to 21 percent silicon and 2.5 percent carbon.
This material is produced by melting slag from high carbon ferromanganese or manganese ore along with coke and quartz flux. This ferroalloy can be used as an alternative to ferrosilicon and ferromanganese and in the direction of deoxygenation during steel production.
The effect of adding silicon manganese to steel is added to the amount and its combined effect with other elements in the melt. Ferrosilicon manganese with a silica content above 30 is used in the production of stainless steel.
Oxidation with ferrosilicon manganese leads to cleaner steel, because liquid manganese silicate coagulates and separates more easily from the melt. The use of ferrosilicon manganese adds less phosphorus, carbon and nitrogen to the steel than the combination of ferrosilicon and ferromanganese.
Also, calculations performed by fluid dynamics show that Si reception through Si-Mn is higher than its reception through Fe-Si.
