Ferrosilicon is an alloy of iron and silicon. Ferrosilicon is an iron silicon alloy made from coke, steel chips and quartz (or silica) by electric furnace smelting.
Use of ferrosilicon:
(1) Ferrosilicon is a deoxidizer in steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as alloying agent in steelmaking.
(2) It is used as inoculant and spheroidizing agent in cast iron industry. In the production of nodular cast iron, ferrosilicon is an important inoculant (to help precipitate graphite) and spheroidizing agent.
(3) Used as reducing agent in ferroalloy production. Not only the chemical affinity between silicon and oxygen is great, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high silicon ferrosilicon (or siliceous alloy) is a common reducing agent in the production of low-carbon ferroalloy in ferroalloy industry.
(4) 75# ferrosilicon is often used in the high-temperature smelting of metal magnesium in the process of magnesium smelting by Pijiang method The replacement of magnesium in MgO will consume about 1.2 tons of ferrosilicon for each ton of metal magnesium, which plays a great role in the production of metal magnesium.
(5) For other purposes. Ground or atomized ferrosilicon powder can be used as suspended phase in beneficiation industry.
(6) It can be used as the coating of electrode in electrode manufacturing industry. High silicon ferrosilicon can be used to manufacture silicone and other products in the chemical industry.
In addition, ferrosilicon powder can be used as suspended phase in beneficiation industry and coating for electrode in electrode manufacturing industry. In steelmaking industry, about 3 ~ 5kg75% ferrosilicon is consumed per ton of steel. Melting point: 75fesi 1300 ℃
Packaging of ferrosilicon:
Specification: particle size: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm or customized;
Packing: ton bag, 1000kg / bag.
