What is high carbon silicon?

High-carbon silicon as an alloy of silicon and carbon. It is a new type of alloy used in converters. This product is a by-product of silicon metal production. The main components of high carbon silicon are silicon and carbon. The silicon content is generally above 55%, while the carbon content is above 15%. Other components include silicon dioxide, phosphorus and sulphur.

What is the advantages of high carbon silicon?

As a new type of composite alloy deoxidiser, high-carbon silicon has an absolute price advantage compared to other types of deoxidisers and can replace traditional deoxidisers such as ferrosilicon powder, calcium carbide, carbon powder, alloy powder, etc. High carbon silicon has stable physical characteristics and chemical properties and good deoxidation effect. Used in the steel making process of the converter, it can quickly react with the oxygen in the molten steel to form steel slag floating on the surface of the molten steel, thus achieving the purpose of deoxidation. High-carbon silicon has certain desulphurisation and recarburisation effects while deoxidising, which can replace part of the recarburiser, thus greatly reducing the amount of carbon in the steel.

What is the usage of high carbon silicon?

High carbon silicon is rich in silicon. In the steelmaking process, it is necessary to oxygenate the molten steel so that it quickly reaches the ideal temperature. In the subsequent stage, it is necessary to treat the oxygen in the molten steel; otherwise, a large amount of oxides will be produced, which will affect the quality of the steel. After the use of high-carbon silicon, the internal silicon element can quickly generate silica gas with oxygen, taking most of the oxygen in the molten steel, reducing the amount of oxides in the molten steel and making most of the oxides and miscellaneous items float. The surface of the molten steel to facilitate cleaning and effectively improve the purity of the molten steel. The carbon in the high-carbon silicon also regulates the carbon element in the molten steel, thus improving the toughness and hardness of the steel. In the casting process, it is necessary to inoculate the cast iron. The use of high-carbon silicon can greatly improve the inoculation effect, which increases the amount of eutectic granules in the cast iron and improves the quality of the cast iron. At the same time, high-carbon silicon can also promote the flow properties of cast iron and reduce the occurrence of blockages in the water outlet. In the production process of graphite cast iron, high-carbon silicon can effectively improve the structure and distribution of graphite and reduce the tendency of whiteness, greatly improving the quality of cast iron.
