Silicon-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. Silicon-manganese alloy is a composite deoxidizer commonly used in steelmaking, and is also a reducing agent for the production of medium and low carbon ferromanganese and the production of metal manganese by electrosilicon thermal method.


Silicon manganese alloy application:

Silicon manganese alloy is mainly used as the intermediate material of deoxidizer and alloying agent in iron and steel production, and also the main raw material of medium and low carbon ferromanganese production.

Silicon-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. Its consumption occupies the second place in electric furnace ferroalloy products. Silicon and manganese in silicon-manganese alloy have a strong affinity with oxygen. When silicon-manganese alloy is used in steelmaking, the resulting deoxidation products MnSiO3 and MnSiO4 melt at 1270°C and 1327°C respectively, with low melting point, large particles and easy to float. , good deoxidation effect and so on. Under the same conditions, using manganese or silicon alone for deoxidation, the burning loss rate is 46% and 37%, respectively, while with silicon-manganese alloy deoxidation, the burning loss rate of the two is 29%. Therefore, it has been widely used in steelmaking, and its output growth rate is higher than the average growth rate of ferroalloys, and it has become an indispensable composite deoxidizer and alloy additive in the iron and steel industry. Silicon-manganese alloys with a carbon content of less than 1.9% are also semi-finished products used for the production of medium and low carbon ferromanganese and electro-silicothermal metal manganese.


In ferroalloy production enterprises, the silicon-manganese alloy used in steelmaking is usually called commercial silicon-manganese alloy, the silicon-manganese alloy used in smelting low carbon iron is called self-use silicon-manganese alloy, and the silicon-manganese alloy used in metal smelting is called high silicon alloy. Silicon manganese alloy. Manganese can be combined with silicon to form silicides MnSiO3, MnSiO and MnSiO3.
