Silicomanganese

silicomanganese

[¦sil·ə·kō′maŋ·gə‚nēs]
(metallurgy)
A crude alloy made up of 65-70% manganese, 16-25% silicon, and 1-2.5% carbon; used in the manufacture of low-carbon steel.

Silicomanganese

 

a ferroalloy composed chiefly of silicon and manganese; it is smelted by carbon reduction in ore heat-treating furnaces. Silicomanganese with 10–26 percent Si (the remainder is Mn, Fe, and impurities) is obtained from manganese ore, manganese slag, and quartzite and is used as a deoxidizer and alloying additive in the smelting of steel, as well as in the smelting of ferromanganese with reduced carbon content by the silicothermic process. Silicomanganese with 28-30 percent Si, for which specially prepared high-manganese low-phosphorous slag serves as raw material, is used in the production of metallic manganese.
