1. Property and characteristics:
1). Reducing chilling tendency significantly and relative hardness, improve machinability.
2). High anti-decline ability, prevent declining of inoculants and nodular iron.
3). Enhance the cross section uniformity and prevent the shrink tendency.
4). Steady chemical composition. Even processing granularity. Small deviation in quality and redients.
5). Low melting point(approaching 1300ºC). Easy for melting absorb and has little dross.

2. Description
silicon manganese alloy is an alloy made of manganese,silicon,iron and small amounts of carbon and
other elements.Silicon manganese alloy is used as compound deoxidizer, also reducing agents of the production of low-carbon ferro manganese and manganese silicon thermal power production.Manganese
and silicon are the main alloying elements in the steel.Manganese is one of the main deoxidizers n steel-making process, further more, almost all kinds of steel are required touse manganese deoxidation.Because when deoxidize with manganese to generated oxygen product with low melting point,easy torise;Manganese
also increases strength of silicon and aluminum deoxidation effect.All industrial steel are to be added a small amount of manganese as a desulfurization agent,the steel can be hot rolling,forging and other
processes without breaking,manganese,or the most importan ttypes of steel,the alloy
elements in the alloy is also added 15% Mn above to increase the structural strength of steel.

4. Application
Silicon manganese alloy is used as compound deoxidizer, also reducing agents of the production of low-carbon ferro manganese and manganese silicon thermal power production.Manganese and silicon are the main alloying elements in the steel. Manganese is one of the main deoxidizers in steel-making process, further more, almost all kinds of steel are required touse manganese deoxidation. Because when deoxidize with manganese to generated oxygen products with low melting point, easy to rise; Manganese also increases strength of silicon and aluminum deoxidation effect. All industrial steel are to be added a small amount of manganese as a desulfurization agent, the steel can be hot rolling, forging and other processes without breaking, manganese, or the most importan ttypes of steel,the alloy elements in the alloy is also added 15% Mn above to increase the structural strength of steel.
(1) in the steel industry used as deoxidizer and alloying agents.
(2) in the iron industry used as a nucleating agent and spheroidizing agent. Cast iron is a kind of important modern industrial metal materials, it is much cheaper than steel, easy to melt refining, excellent casting performance and seismic capacity is far better than steel. Especially the nodular cast iron, its mechanical performance at or near the steel mechanical property. Add a certain amount of silicon in cast iron can prevent iron in formation and precipitation of carbides, and promote the graphite spheroidizing, therefore in the nodular iron production, ferrosilicon inoculants is a kind of important separation graphite (help) and spheroidizing agent.
(3) used as a reductant in ferroalloy production. Not only chemical affinity between silicon and oxygen is very big, but also high silicon silicon carbon content is very low. So high silicon ferrosilicon (or siliceous alloy) is a low-carbon ferroalloy ferroalloy industry production more commonly used a reducing agent.
