Ferrosilicon is a ferroalloy composed of silicon and iron. It is an important metallurgical raw material in the field of metallurgical cast iron. Ferrosilicon is complete in specifications and diverse in types.
Ferrosilicon 75, also known as ferrosilicon alloy 75, plays an irreplaceable role in the field of metallurgy.Standard specification of ferrosilicon 75 is: particle size: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized.It is usually packed in ton bags with a melting point of 1300 degrees.The use of ferrosilicon 75 mainly has the following points:
(1) ferrosilicon is an essential deoxidizer in steelmaking industry.In steelmaking, ferrosilicate is used for precipitation deoxidation and diffusion deoxidation.Brick iron is also used as an alloying agent in steelmaking.
(2) Used as inoculant and spheroidizer in cast iron industry.In ductile iron production, 75 ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizer.
(2) used as reducing agent in ferroalloy production.Not only is the chemical affinity between silicon and oxygen great, but the carbon content of high silicon ferrosilicon is very low.Therefore, high silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low carbon ferroalloy in the ferroalloy industry.
(4)75 ferrosilicate in Pijiang magnesium smelting is often used in the high temperature smelting process of magnesium, the magnesium replacement in CaO.MgO, each one ton of magnesium will consume about 1.2 tons of ferrosilicate, which plays a great role in the production of magnesium.
(5) for other purposes.Grinded or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.
(6) in the electrode manufacturing industry can be used as electrode coating.High silicon ferrosilicon in the chemical industry can be used to manufacture silicone and other products
Henan star production of ferrosilicon 75 standard qualified, stable quality, reasonable price, has been the new and old customers unanimously recognized, looking forward to your purchase!
