1. What is ferrosilicon?
Ferrosilicon is an alloy made of coke, scrap steel and silica as raw materials and smelted by electric furnace. In the iron and steel industry, ferro silicon is an essential metallurgical raw material.
2. What are the characteristics of ferrosilicon?
Ferrosilicon has a silver metallic luster, and the thickness of its natural block is about 100mm. Ferrosilicon is easily affected by water and is easily crushed when exposed to water. After that, the silicon content will decrease.
3. What are the industrial uses of ferrosilicon?
As a deoxidizer in crude steel smelting and iron and steel industry, ferrosilicon is an essential metallurgical raw material. When SiO2 is generated, a lot of heat is released, which is beneficial to increase the temperature of molten steel while deoxidizing. As an alloying element additive, ferrosilicon is widely used in low-alloy structural steel, alloy steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. High-silicon ferrosilicon or siliceous alloys are used as reducing agents in the production of low-carbon ferroalloys in the ferroalloy industry. Ferrosilicon added to cast iron can be used as an inoculant for ductile iron, which can prevent the formation of carbides and promote the precipitation and spheroidization of graphite. It can also improve the properties of cast iron. In the smelting process of metal magnesium, a large amount of ferrosilicon is also required as an additive.
4. What are the factors that affect the price of ferrosilicon?
(1) Electricity price
(2) Prices of raw materials such as coke, steel sheet, quartz (or silica)
(3) Government environmental protection policies
