Ferro Silicon Can Be Used As A Deoxidizer

Deoxidation Principle Of Ferro Silicon

As ferro silicon contains a large amount of silicon, when using ferro silicon in steelmaking, as the ferro silicon melts in the molten steel, silicon reacts chemically with oxygen, generating silicon dioxide gas, which is discharged through the ventilation pipe, thus effectively reducing the oxygen in the molten steel, lowering the number of oxides in the molten steel and improving the shape of the inclusions, so that the impurity floats on the surface of the molten steel, which is easy to clean up, and effectively improves the purity of the molten steel.

Ferro Silicon Grade Specification For Deoxidizers

Advantages Of Using Ferro Silicon As A Deoxidizer In Steelmaking

At present, ferro silicon has become an important deoxidizer in steelmaking. Its advantage lies in the use of ferro silicon can significantly enhance the strength, hardness and elasticity of steel, not only that, ferro silicon can also effectively reduce the harmful elements in steel, such as: sulfur, phosphorus, etc., and has the advantages of large specific gravity, strong penetration, in structural steel, tool steel, spring steel and transformer silicon steel is currently the main application of ferro silicon, as an important alloying agent to use.

ferro silicon for casting not only has the effect of deoxidizing, but also effectively improves the breeding effect and the number of eutectic pellets. In the production of graphite cast iron, ferro silicon can effectively improve the distribution pattern of its internal graphite, and promote the generation of graphite nuclei, reducing the phenomenon of white mouth tendency in castings. Go to Understanding Ferro Silicon Inoculants

Because silicon and oxygen have an affinity effect, especially in steelmaking, the chemical reaction process is more stable, therefore, the use of ferro silicon as a deoxidizer in steelmaking has many advantages such as fast deoxidizing speed, good effect, high safety and easy to operate, etc. At the same time, ferro silicon compared to the traditional deoxidizers to reduce the price, which can effectively improve the quality of steel and reduce the deoxidizing cost of steelmaking to enhance the efficiency of the manufacturers, which is the reason why more and more steel mills choose ferro silicon as the deoxidizing agent, which is the most effective way to improve the quality of steel. This is the important reason why more and more steel mills choose ferro silicon as deoxidizer.

Prospects For Ferro Silicon As A Deoxidizer

With the gradual expansion of urban construction and development of steel demand, ferro silicon as a kind of steelmaking deoxidation low cost, good effect of ferroalloy products have a better development prospects. According to statistics, the annual ferro silicon used for deoxidation accounts for more than 90% of the annual ferro silicon production. With the development of ferro silicon industry chain is becoming more and more perfect, ferro silicon has become an important raw material for deoxidation in the field of steelmaking, in the mining of raw materials of ferro silicon, and then to the smelting production and processing of ferro silicon, has formed a mature market and operation system.

Precautions Of XLS Metals ferro silicon As Deoxidizer

Xinlongsen is a ferro silicon manufacturer with many years of production experience, according to the silicon content of ferro silicon, its production of ferro silicon can be mainly divided into 75%, 72%, 65% and 45% grades, these grades of ferro silicon is mainly used in the field of steelmaking and casting, and is widely acclaimed as a deoxidizer in steelmaking. It is important to note that the user in the purchase of ferro silicon, according to different uses, choose different grades of ferro silicon and types of ferro silicon, of which the steelmaking ferro silicon users mainly 75% and 72% of the two silicon content of ferro silicon is the main, and smelting of special steel, such as: structural steel, bearing steel, and other steel users may need to purchase low-aluminum ferro silicon or high-purity ferro silicon, and the particle size of 10mm ~ 60mm for the best choice. Users of ferro silicon for casting generally require low nitrogen and low sulfur, which can effectively improve the yield of castings.
