Description of Calcium Silicon

Calcium silicon(CaSi) is a silicon calcium alloy obtained from silica, lime, and coke in a strong reducing atmosphere at 1500-1800 degrees. Its main components are silicon and calcium, and it also contains impurities such as iron, aluminum, carbon, sulfur, and phosphorus in varying amounts. In the iron and steel industry, it is used as a calcium additive, deoxidizer, desulfurizer, and denaturant for non-metallic inclusions. It is used as an inoculant and denaturant in the cast iron industry.

Calcium silicon is also called CaSi alloy, or calcium silicon alloy. It can be customized as powder, granule, or lump.

Advantages of Calcium Silicon

• Enhancing the plasticity, impact toughness, and fluidity of steel.

• Substitute for aluminum in final deoxidation.

• As a warming agent in converter steelmaking workshops.

• As an inoculant in cast iron production and as an additive in ductile iron and nodular cast iron production.

Application of Calcium Silicon

Calcium Silicon Granules

Calcium Silicon Granules

• Steel Production: Calcium Silicon is a crucial additive in steelmaking. It is added to the molten steel to improve its properties. It helps deoxidize and desulfurize the steel, resulting in better quality and performance of the final steel products.

• Alloying Agent: In the manufacturing of various alloys, such as aluminum alloys, Calcium Silicon is used as an alloying agent to enhance the material’s strength, durability, and other desired characteristics.

• Deoxidizer in Non-Ferrous Metals: It is also used as a deoxidizing agent in the production of non-ferrous metals like copper and nickel. This helps eliminate impurities from the metal, ensuring a high-quality end product.

• Inoculant in Iron Foundries: Calcium Silicon is employed as an inoculant in iron foundries. It promotes the formation of graphite in cast iron, improving its mechanical properties.

• Chemical Industry: In some chemical processes, Calcium Silicon can be used as a reducing agent, aiding in chemical reactions and the production of various compounds.

• Improving Heat Resistance: When added to certain materials, such as ceramics, Calcium Silicon can enhance their heat resistance and mechanical properties.

• Fuel Additive: In some cases, it is used as a fuel additive to control the ignition of fuels like diesel, helping reduce emissions and improve combustion efficiency.
