Introduction of ferromanganese powder use

Ferromanganese powder namely ferromanganese with machine processing into powder.An aggregate of iron particles smaller than 1mm in size.Color: black.It is the main raw material of powder metallurgy.According to particle size, it is customarily divided into five grades: coarse powder, medium powder, fine powder, fine powder and ultra-fine powder.Iron powder with particle size in the range of 150 ~ 500μm is coarse powder, with particle size in the range of 44 ~ 150μm is medium powder, with particle size in the range of 10 ~ 44μm is fine powder, with particle size in the range of 0.5 ~ 10μm is very fine powder, and with particle size less than 0.5μm is ultra-fine powder.

The main use of ferromanganese powder has the following aspects:

1, steel industry: ferromanganese powder is indispensable in steelmaking industry deoxidizer, desulfurizer.Good need in smelting, steel deoxidation desulphurization processing, and using deoxidizing agent will greatly increase the cost, therefore, ferromanganese is a cheap deoxidizer, desulfurization is refers to the sulfur in the steel from harmful substances, such as ferromanganese we can achieve the purpose of the desulfurization very well, effectively reduce the content of harmful elements in steel, improve the quality of steel.In steelmaking industry, about 3 ~ 5kg75% ferromanganese is consumed for each ton of steel produced.

2, casting industry: fermanganese powder can be used as inoculant and nodular cast iron in cast iron, and can prevent the formation of carbide, promote the precipitation of graphite greatly shorten the spheroidizing time, but also can greatly reduce the shape of impurities in molten iron, improve the quality of cast iron, improve the performance of cast iron.And reduce the smelting furnace nozzle blockage, effectively prolong the service life of smelting furnace.

3, other industries: high carbon ferromanganese or manganese alloy in the ferroalloy industry as a reducing agent for the production of low carbon ferroalloy.Ferromanganese powder in the mineral processing industry can be used as a suspended phase, in the electrode manufacturing industry for electrode coating;High manganese ferromanganese in the electrical industry can be used to prepare semiconductor pure manganese, in the chemical industry can be used to manufacture manganone, etc.
