Silicon Manganese 6014

Brief introduction

Introduction to Basic Knowledge of Silicon Manganese Alloy Introduction to Basic Knowledge of Silicon Manganese Alloy 1. Concept: Silicon manganese alloy is an alloy composed of manganese, silicon, iron, and a small amount of carbon and other elements. It is a widely used and high-yield iron alloy. Silicon manganese alloy is a commonly used composite deoxidizer in steelmaking, and also a reducing agent for low-carbon manganese iron and electro silicon thermal production of metallic manganese in production.

Product Information

Silicon-manganese alloysIt is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements, and is a ferroalloy with a wide range of uses and large output. Its consumption accounts for the second place of electric furnace ferroalloy products, manganese and silicon in manganese-silicon alloy have a strong affinity with oxygen, and manganese-silicon alloy is used in steelmaking, and the deoxidation product MnSiO is produced3and Mn2SiO4The melting points are 1270 °C and 1327 °C, respectively, and have the advantages of low melting point, large particles, easy to float, and good deoxidation effect. Under the same conditions, the burn-out rate of manganese or silicon alone is 46% and 37%, respectively, while the burn-out rate of manganese-silicon alloy is 29%.

It has been widely used in steelmaking, and its output growth rate is higher than the average growth rate of ferroalloys, higher than the growth rate of steel, and has become an indispensable composite deoxidizer and alloy additive in the steel industry. Manganese-silicon alloys with a carbon content of less than 1.9% are also semi-finished products used in the production of medium and low-carbon ferromanganese and electrosilicon thermal manganese metal.

Silicon-manganese alloy is mainly used as an intermediate material for deoxidizer and alloying agent in steel production, and at the same timeMedium and low carbon ferromanganeseThe main raw material for production.

Silicon-manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements, which is a widely used and large out putferroalloy。 Its consumption accounts for the second place in the ferroalloy products of electric furnaces. The silicon and manganese in the silicon-manganese alloy have a strong affinity with oxygen, and the silicon-manganese alloy is used in steelmaking to produce the deoxidation product MnSiO3and MnSiO4The melting is 1270 °C and 1327 °C, respectively, which has the advantages of low melting point, large particles, easy floating, and good deoxidation effect. Under the same conditions, the burn-out rate of manganese or silicon alone is 46% and 37%, respectively, while that of silicon-manganese alloy deoxidation, the burn-out rate of the two is 29%. As a result, it is widely used in steelmaking, and its output is growing faster than that of ferroalloysAverage growth rateIt has become an indispensable composite in the steel industryOxygen absorber and alloy additives. Silicon-manganese alloys with a carbon content of less than 1.9% are still used in the production of medium and low carbon ferro manganese and electro silicone thermal methodManganese metal semi-finished products.

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 for metal smelting is called high-silicon-silicon-manganese alloy. Manganese can be combined with silicon to form silicide MnSiO3, MnSiO, and MnSiO3。 As can be seen from the silicon-manganese state diagram, the most stable silicide is MnSi. because manganese. The negative value of the free energy generated by the silicide, so it is much greater than the negative value of the free energy produced by the carbide of manganeseSilicon-manganese alloysThe higher the silicon content, the lower the carbon content.
