What is the difference between ferrosilicon, ferrosilicon powder and silica fume? Let's take a look:
Ferrosilicon is made from coke, steel chips and quartz (or silica) by electric furnace smelting. Silicon and oxygen are easily converted into silica. Therefore, ferrosilicon is often used as deoxidizer in steelmaking. At the same time, due to the large amount of heat released during the formation of SiO2, it is also beneficial to improve the temperature of molten steel while deoxidizing. Ferrosilicon is used as alloying element additive. It is widely used in low alloy structural steel, bonded steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is commonly used as reducing agent in ferroalloy production and chemical industry. The silicon content is 95% 99%. Pure silicon is often used to manufacture monocrystalline silicon or prepare nonferrous metal alloys.
Ferrosilicon powder: the composition is basically the same as that of ferrosilicon. It is commonly 75#, 72#, 70#, 65#, 60# ferrosilicon powder.
Silica fume: it is a by-product of ferrosilicon production.
