First of all, the silicon-manganese alloy is composed of manganese, silicon, iron and a small amount of carbon and other elements of the alloy, is a more widely used, larger output of iron alloy.
Secondly, si-mn alloy is the main raw material of Low Carbon Ferromanganese production as the deoxidizer and the intermediate of alloying agent in steel production.
Finally, SI-MN alloy is also a common composite deoxidizer in steelmaking, and it is also a reducing agent in the production of medium-low carbon ferromanganese and metal manganese by electrosilicothermic method.
