Ferrosilicon
Molecular formula: FeSi, ferroalloy composed of iron and silicon (with silica, steel, coke as raw materials, after 1500-1800 degrees of high temperature reduction of silicon fused in liquid iron, forming ferrosilicon alloy). It is an important alloy variety in the smelting industry.

use
(1) Be used as deoxygenation agent and alloy agent in the steelmaking industry.
(2) used as incubation agent and casting iron agent.
(3) Be used as a reducing agent in ferroalloy production.
(4) 75 # ferrosilicon is often used in the high temperature smelting process of magnesium in Pijiang magnesium smelting, and the replacement of magnesium in CaO.MgO plays a great role in the production of magnesium.
(5) In other purposes. Grilled or atomized ferrosilicon powder can be used as a suspension phase in the mineral processing industry. Coatings that can be used as welding electrodes in the electrode manufacturing industry. High silicon ferrosilicon can be used in manufacturing silicone and other products in the chemical industry.
