Anyang County Deyi shelf silico-manganese alloy plant

Manganese alloy is an alloy made of manganese, silicon, iron and a small amount of carbon and other elements, which is a wider use, a large ferroalloy production. Silicon manganese alloy steel commonly used compound deoxidizer, but also reducing the production of low-carbon ferromanganese and silicon thermal power production of manganese metal. Manganese and silicon is the main alloying elements in steel used. Manganese is one of the main steelmaking process deoxidizer, almost all steel grades are required to deoxidation with manganese. Because of the low melting point of manganese oxide product to deoxy-generated, easy to float; manganese can increase the oxygen effect of silicon and aluminum and other strong deoxidizer. All the steel industry are required to add a small amount of manganese as a desulfurization agent, the steel can be hot rolling, forging and other processes without breaking, manganese or various grades of the most important alloying element in the alloy will also add 15% or more of manganese to increase the structural strength of steel. Silicon is second only to iron and manganese steel most important alloying elements. In steel production, silicon is mainly used as a deoxidizer of molten metal, or as an alloying additive to increase the strength of the steel and improve its performance. Silicon is also an effective medium of stone technology, which enables the cast of carbon into carbon-free stone. Join standard gray cast iron and nodular cast iron silicon up to 4%. And a large number of manganese and silicon in the form of ferro-alloys are added to the molten steel: ferromanganese, silicomanganese and ferrosilicon. Production of silicon manganese alloy raw materials manganese ore, manganese-rich slag, silica, coke, dolomite (or limestone), fluorite. Production of silicon manganese alloy may use one or more of manganese ore (including manganese-rich slag) mixed ore. Since silicon manganese alloys require iron, phosphorus content is lower than the high-carbon ferromanganese, and called for smelting manganese silicon manganese alloys have higher than ferromanganese and manganese, phosphorus ratio. The higher the manganese ore used, the indicators, the better. 2. Market Demand Forecast of China's urbanization and industrialization along with the deepening of the demand for increasing the amount of steel, demand for silicon manganese alloys will continue to grow. 2009 1--11 months, one million tons of crude steel production of 518.177, an increase of 12.1%, manganese silicon alloy 7.103 one million tons, an increase of 28.3%, for the rapid growth in the field of metallurgy. With the continuous development of China's economic development, automobile, road, construction, real estate and other markets, the demand for steel will continue to increase, and therefore the demand for silicon manganese alloys will continue to increase. Thus manganese alloy has good market prospects
