Silicon manganese alloy (SiMn)is composed of silicon,manganese,iron,little carbon and some other elements.lt islumpy material with a silvery metallic surface. Effects of the addition of silicomanganese to steel: Both silicon andmanganese have an important influence on the properties of steel, depending on the amount added and thecombined effect with other alloying elements,According to the contenr of silicon and manganese,it can be divide intoFeMn68Si18,FeMn64Si16 and non-standard customized products.
Silicon manganese alloy main raw material are manganese ore,manganese-rich slag,silica,coke,lime,ect.Si-mn alloy canbe smelted by continuous operation in large, medium and small ore furnaces.
It is a cost- effective blend of manganese and silicon and is normally the product of choice for steel manufacturers. ltis consumed in all steel products and used in higher quantities in 200 series stainless steel, alloy steel and manganesesteel.
Silicon-manganese alloy is an alloy composed of Mn,Si, iron and a small amount of carbon and other elements. Wide use, high output. Its consumption ranks second in electric furnace ferroalloy products. Silicon Manganese is used as a deoxidizer and an alloying element in steel.
Silicon manganese is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is a kind of ferroalloy with a wide range of uses and large output, and it ranks second in the amount of ferroalloy products for electric furnace.
Both manganese and silicon in the Mn-Si alloy have a strong affinity with oxygen. When manganese-silicon alloy is used in steelmaking, the melting points of the deoxidized products MnSiO3 and Mn2SiO4 are 1270℃ and 1327℃, respectively, which have low melting point, large particles, and easy to float , good deoxidation effect and other advantages.
Under the same conditions, when manganese or silicon is used alone for deoxidation, the burning loss rates are 46% and 37%, respectively, while for manganese-silicon alloy deoxidation, the burning loss rates of both are 29%.
SiMn is often used in steel mill production. The Mn and Si in the silicon-manganese alloy have a strong affinity for oxygen. The melting points of the deoxidized products MnSiO3 and Mn2SiO4 are 1270℃ and 1327℃, respectively. It has the advantages of low melting point, large particles, easy to float, and good deoxidation effect. Under the same conditions, when Mn or Si is used alone for deoxidation, the burning rate is 46% and 37%, respectively. With Silicon-manganese alloy deoxidation, the burning loss rate of the two is only 29%. Therefore, it has been widely used in steelmaking. The growth rate of SiMn output is higher than the average growth rate of ferroalloys and higher than that of steel. It has become an indispensable composite deoxidizer and alloy additive in the steel industry.
Silicon manganese alloy is mainly used as an intermediate material for deoxidizer and alloying agent in iron and steel production, and is also the main raw material for the production of medium and low carbon ferromanganese.
Silicon manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is an iron alloy with a wide range of uses and a large output.
The deoxidation products produced by the silicon manganese alloy have the advantages of low melting point, large particles, easy floating, and good deoxidation effect.
Silicon manganese alloys with a carbon content of less than 1.9% are also semi-finished products for the production of low carbon ferro manganese and electrolytic Manganese metal.
For aluminum alloy products: adding silicon metal to aluminum alloy to improve its strength, increase its oxidation and corrosion resistance, reduce its density and thermal expansion coefficient, improve its casting performance, leading to higher impact resistance and pressure resistance.
For cold-rolled silicon steel products: Adding silicon metal to steel can greatly improve its magnetic properties, increase its permeability, and reduce hysteresis and eddy current loss.
For high-purity semiconductor products: Due to the high melting point of silicon, good thermal stability, large band gap, and abundant resources, with the continuous improvement of technology, integrated circuits and large-scale integrated circuits made of silicon semiconductors have been used in various fields, with increasing demand year by year.
For organic silicone products: organic silicone, silicone resin, and silicone oil maintain flexibility in the range of more than 700°C to 2000°C, and can be used for high-temperature gaskets and cold-preservation materials. Silicone resin: it is used in the production of insulating varnish, with the heating temperature of 180-2000°C, and can also be used in the production of high-temperature resistant coatings. Silicone oil: it is used in the production of high-grade lubricants, polishing agents, fluid springs, and dielectric fluids. It can also be processed into colorless transparent liquids and sprayed on buildings for waterproofing. Silicon metal has a tendency to be more widely used in the organic silicon industry than in the aluminum alloy industry.
For heat-resistant material products: it is used for the production of Si3N4, which is heat-resistant, wear-resistant, and corrosion-resistant, preventing coating materials from oxidation. Siliconizing steel surface can improve the corrosion resistance of steel.
Silicon manganese alloy is main function for the steel-making is alloying agent, compound deoxidizer, desulfurizer
lt can be inprove the casting physical performance and mechanical capacity,strengthen the intensity and wear-resisting property.
lt is a reducing agent for producing medium and low carbon ferro manganese and producing metal manganese by electric silicon thermal method.
