Ductile Cast Iron FeSi 72% Ferro Silicon Lumps

Purity Ferro Alloy Metal FeSi Lump For Making Ductile Cast Iron

FeSi Introduction:

     Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is a ferrosilicon alloy made from coke, scrap iron and quartz (or silicon dioxide) smelted in an electric furnace. Steel is usually used as a deoxidizer in the steelmaking process because silicon and oxygen are easily synthesized into silicon dioxide. At the same time, since SiO 2 releases a large amount of heat when it is formed, it is also effective to increase its temperature while deoxidizing molten steel. At the same time, ferrosilicon can also be used as alloy element additives, and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is commonly used as a reducing agent in the manufacture of ferroalloys and the chemical industry.

FeSi Specification:

The raw materials of ferrosilicon:

     Ferrosilicon is made by smelting coke, steel scraps (iron oxide scale), quartz (or silica) as raw materials in an electric furnace. It is an important auxiliary material for cast iron and steelmaking, used to deoxidize and adjust the chemical composition of steel

FeSi Application: 

     1. Ferrosilicon is widely used in steel industry, foundry industry and other industrial production. Ferrosilicon is an essential deoxidizer in the steelmaking industry. In Torch Steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to the steel can significantly increase the strength, hardness and elasticity of the steel, increase the magnetic permeability of the steel, and reduce the hysteresis loss of the transformer steel.
     2. High-silicon ferrosilicon or siliceous alloys are used as reducing agents in the production of low-carbon iron alloys in the ferroalloy industry. Ferrosilicon added to cast iron can be used as an inoculant for nodular cast iron, and can prevent carbide formation, promote precipitation and spheroidization of graphite, and improve the properties of cast iron.
     3. Ferrosilicon powder can be used as a suspension phase in the beneficiation industry, and as a coating for welding rods in the electrode manufacturing industry; high-silicon ferrosilicon can be used to prepare pure semiconductor silicon in the electrical industry, and can be used to make silicone in the chemical industry.
