Ferrosilicon is made from coke, steel shavings, and quartz (or silica) by smelting in an electric furnace. Silicon and oxygen are easily synthesised into silicon dioxide. So ferrosilicon is often used in steelmaking as a deoxidising agent, at the same time, due to the SIO2 generated when a large amount of heat is released, in the deoxidising at the same time, to improve the temperature of the molten steel is also favourable.
Ferrosilicon is used as an alloying element additive. Widely used in low alloy structural steel, composite steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, in addition to ferrosilicon in the production of ferroalloys and the chemical industry, commonly used as a reducing agent. Silicon content of 95% 99%. Pure silicon is commonly used in the manufacture of monocrystalline silicon or the preparation of non-ferrous metal alloys.
Ferrosilicon Powder: The composition is basically the same as ferrosilicon, commonly 75#, 72#, 70#, 65#, 60# ferrosilicon powder.
Silica Fume: a by-product of ferrosilicon production.
