Silicon manganese alloy

Silicon-manganese alloy is not only the main raw material for the production of low-carbon ferromanganese, but also can be used as a deoxidizer for steel production and an intermediate material for alloying agents. Silicon-manganese alloys with a carbon content of less than 1.9% are still semi-finished products for the production of medium and low-carbon ferromanganese and electrosilicothermal manganese. In ferroalloy production enterprises, silicon-manganese alloys used in steelmaking are usually called commercial silicon-manganese alloys, silicon-manganese alloys used in smelting low-carbon iron are called self-use silicon-manganese alloys, and silicon-manganese alloys used in metal smelting are called high-silicon alloys. Silicon manganese alloy. Silicon-manganese alloys can be used in the steelmaking process because silicon and manganese in the composition have a strong affinity with oxygen. They are alloys with the advantages of low melting point, good deoxidation effect, large particles and easy floating.

In the steelmaking process, the silicon-manganese alloy is used for deoxidation under the same conditions, and the burning loss rate of the two elements is lower than that of using silicon or manganese alone. Therefore, silicon-manganese alloys are widely used in steelmaking, and are composite deoxidizers and alloy additives in the steel industry.
