What is Silicon Manganese？
Silicon Manganese is an alloy with 65% to 68% manganese, 16% to 21% silicon, and 1.5% to 2% carbon. It is produced by smelting of slag from high-carbon Ferro Manganese or of Manganese ore with coke and a quartz flux. Smelting temperatures are high and greater energy is needed to reduce the quartz to silicon. So, the process requires power consumption of about 3,800 to 4,800 kilowatt-hours per tonne. Silicon manganese (SiMn) is an iron alloy with a high content of manganese and silicon that is made by heating a mixture of 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 a gold element in steel.
Uses of Silicon Manganese
Silicon manganese alloy is mainly used as an intermediate material of deoxidizer and alloying agent in steel production, and is also the main raw material for medium and low carbon ferromanganese production.
