Ferrosilicon is an alloy material containing iron and silicon, which has a series of excellent physical and chemical properties. Compared with fesi with low silicon content, ferrosilicon alloy with high silicon content has more stable quality and is more suitable for use in industry.
Its specific characteristics are as follows:
High hardness
Ferrosilicon with high silicon content has higher hardness than ferrosilicon with low silicon content, because the addition of silicon can increase the hardness of the alloy.
High strength
The hardness and strength of ferro silicon are in the same proportion.
Strong corrosion resistance
Ferrosilicon itself has good corrosion resistance, and fesi with higher silicon content is more outstanding in this regard. It can resist some common corrosion and oxidation phenomena.
Strong oxidation resistance
It is not easily oxidized at high temperatures, while ferrosilicon with high silicon content is more likely to resist the effects of oxidation.
Application of ferrosilicon with high silicon content
Ferrosilicon with high silicon content is widely used in metallurgy, construction, machinery manufacturing and other fields.
Specific applications include:
Alloy smelting
Ferrosilicon can be used as an important raw material for smelting cast iron, steel and other alloy materials. Ferrosilicon with high silicon content can better meet the requirements of different alloy manufacturing.
Building materials
Ferrosilicon can also be used to make building materials such as glass and ceramics. Ferrosilicon with high silicon content can provide better hardness and corrosion resistance for these materials.
Machinery manufacturing
Ferrosilicon is also widely used in machinery manufacturing, automobile manufacturing and other industries. Ferrosilicon with high silicon content can improve the hardness and corrosion resistance of products in these industries, thereby extending their service life.
Manufacturing process of ferrosilicon with high silicon content
Ferrosilicon with high silicon content can be manufactured by a variety of methods, the most commonly used of which are fuel method and electric furnace method. Among them, the fuel method is divided into blast furnace method and converter method, both of which use coal, coke and the like as reducing agents to reduce silicon and iron to make ferrosilicon alloy.
The electric furnace method mainly refers to the use of electricity to smelt ferrosilicon raw materials, which has more stable quality and higher cost. However, this method can accurately control the composition of the alloy and customize more targeted ferrosilicon with high silicon content.
