First, let's talk about "ferrosilicon". Ferrosilicon is made from silica, steel and coke. Silicon, which has been reduced at a high temperature of 1500-1800 degrees, is melted into ferro-water to form ferrosilicon alloy.
Because silicon and oxygen can easily synthesize silicon dioxide. Therefore, ferrosilicon is often used as a deoxidizer in steelmaking. At the same time, the generation of SiO2 will release a large amount of heat. In the deoxidation at the same time, it is also conducive to increase the temperature of steel.
At the same time, ferrosilicon can also be used as an alloying element additive. It is widely used in low alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in ferroalloy production and the chemical industry.
Ferrosilicon appears in iron and steel smelting as a deoxidizing reducing agent. It mainly utilizes the silicon element in it. The silicon content of ferrosilicon is more than 72%.
Silicon metal is smelted in an electric furnace with quartz and coke. The silicon content is over 98%. The rest of the impurities in silicon metal are iron, aluminum, calcium and so on. Although the market has risen slightly recently. Henan, Shandong and other places of silicon metal ex-factory price including tax is basically in 12000-13000 yuan / ton.
In the steelmaking industry, each ton of steel production consumes about 3-5 kg of 75% ferrosilicon. If replaced by silicon metal, each ton of steel consumes about 2.3-3.6 kg of silicon metal.
