Si - mn alloy is suitable for steelmaking and casting as alloy agent, compound deoxidizer and desulfurizer. As an alloying element, manganese is added to liquid steel to alloyed steel, so as to improve the mechanical properties of steel and increase the strength, hardness, ductility, toughness and wear resistance of steel. Therefore, manganese is an indispensable element in steel production, and almost all steels contain a certain amount of manganese. Adding manganese to cast iron can improve the physical and mechanical properties of castings and increase the strength and wear resistance of castings. Silicon manganese alloy can also be used as the raw material of carbon ferromanganese, low carbon ferromanganese and manganese metal, which is mainly used as the alloy agent of manganese to produce stainless steel. If the user has special requirement for chemical composition, it can be negotiated by both parties.
In the smelting of various grades of manganese series alloys, the manganese content and ferromanganese ratio of ores are required. Smelting medium and low carbon ferromanganese, ore manganese content 36% ~ 40%, ferromanganese ratio 6 ~ 8.5, phosphorus manganese ratio 0.002 ~ 0.0036; Smelting carbon ferro manganese, ore manganese content 33% ~ 40%, ferro manganese ratio 3.8 ~ 7.8, phosphorus manganese ratio 0.002 ~ 0.005; Smelting manganese silicon alloy, ore containing manganese 29% ~ 35%, ferro manganese ratio 3.3 ~ 7.5, phosphorus manganese ratio 0.0016 ~ 0.0048; Blast furnace ferro manganese, ore manganese content 30%, ferro manganese ratio 2 ~ 7, phosphorus manganese ratio 0.005.
