SiMn

Silicomanganese (SiMn), a ferroalloy with high contents of manganese and silicon, is made by heating a mixture of the oxides manganese oxide (MnO2), silicon dioxide (SiO2), and iron oxide (Fe2O3), with carbon in a furnace. They undergo a thermal decomposition reaction. It is used as a deoxidizer and an alloying element in steel. The standard grade silicomanganese contains 14 to 16% of silicon, 65 to 68% of manganese and 2% of carbon. The low carbon grade SiMn has carbon levels from 0.05 to 0.10 % Under key strategic production pre-financed agreements with a number of Ferroaloys processing plants internationally, we regularly supply to an assortment of Steel Mils internationally, with two grades of SIliconmanganese 1) SiMn corresponding to a typical specification of a material with 60% to 65% of Mn content in weight and 2), SiMn corresponding to a material with 65% to 70% of Mn content in weight.
