Ferrosilicon 75

Ferrosilicon is a common deoxidizer. Among many deoxidizers, ferrosilicon not only has obvious deoxidizing effect, but also has a relatively low price, so it is favored by many steel smelters. Ferrosilicon 75 is a kind of ferrosilicon with a silicon content of 75%. It is also a common one in steel smelting, and the deoxidation efficiency is also improved.

75 Ferrosilicon Introduction:

Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. Ferrosilicon 75 has always had a good effect in the steelmaking industry. At the same time, ferrosilicon is also one of the traditional steelmaking materials. Ferrosilicon 75 can be effectively deoxidized in steelmaking, so ferrosilicon 75 can be used as a steelmaking deoxidizer. ; Ferrosilicon 75 contains about 75% silicon, which has a good affinity with oxygen in molten steel. When ferrosilicon 75 is placed in steelmaking, the silicon element in ferrosilicon 75 interacts with oxygen. The affinity effect can effectively discharge the oxygen in the molten steel and can completely replace the deoxidizer.

The use of 75 ferrosilicon:

(1) Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used in steelmaking as an alloying agent.
(2) Used as an inoculant and a nodularizing agent in the cast iron industry. In the production of ductile iron, 75 ferrosilicon is an important inoculant (helping to precipitate graphite) and nodularizing agent.
(3) Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is very high, but also 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 ferroalloys in the ferroalloy industry.
(4) 75 ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon process of magnesium smelting. The magnesium in CaO.MgO is replaced, and about 1.2 tons of ferrosilicon are consumed for each ton of metal magnesium produced. Magnesium metal production plays a big role.
(5) Use in other aspects. The ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.
(6) It can be used as a coating for welding rods in the welding rod manufacturing industry. High-silicon ferrosilicon is used in the chemical industry to manufacture products such as silicone.

Packaging of 75 Ferrosilicon:
Specifications: Granularity: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized.
Packing: ton bag, 1000kg/bag
In addition, 75 ferrosilicon powder can be used as a suspended phase in the mineral processing industry, and used as a coating for welding rods in the welding rod manufacturing industry. In the steelmaking industry, about 3 to 5kg of 75 ferrosilicon is consumed per ton of steel produced.

Ferrosilicon 75 has a good affinity in the process of deoxidation. The reaction of deoxidized molten steel is small, which ensures the safety of personnel. At the same time, the deoxidation time of ferrosilicon 75 is shorter than that of deoxidizer, which reduces the time spent in steelmaking, not only In this way, ferrosilicon 75 is cheaper than the deoxidizer, which can save the cost of the manufacturer in steelmaking and improve the efficiency of the manufacturer.
