Calcium-silicon cored wire is a type of alloy cored wire used for deoxidation, desulfurization and removal of inclusions in the steelmaking and casting process, made from powders or particles of silicon and calcium encapsulated in a metal skin. The action of the calcium-silicon alloy makes it particularly effective in the steel refining process, helping to enhance the purity and properties of the steel.
Calcium Silicon Cored Wire main features and benefits
1. Strong Deoxidizer: Silicon and Calcium react with oxygen in molten steel at high temperatures to produce calcium oxide and silicon oxide, effectively removing oxygen from molten steel and enhancing the purity of steel.
2. Highly efficient desulfurization: Calcium combines with sulfur to generate calcium sulfide with low melting point, which enables it to be separated from the steel water and reduces the sulfur content in the steel.
3. Reducing inclusions: The inclusions generated by the reaction of calcium silicate are small and uniform in particle size, which can significantly reduce the harmful inclusions in steel and improve the quality of the material.
4. Improve steel fluidity and casting performance: Calcium silicate core wire makes the steel flow better in the casting process, reduces casting defects, and improves steel performance.
5. Reduce cost: By precisely controlling the amount of addition, calcium silicate cored wire improves efficiency, reduces alloy loss and has a high cost performance ratio.
calcium silicon cored wire applications
1. Metallurgical Industry: It is widely used in steelmaking for the refining process of low carbon steel, stainless steel, high strength steel, etc. to enhance the purity of steel.
2. Casting process: Calcium silicate cored wire is used in casting to refine grain and improve casting quality, suitable for steel with high quality requirements.
3. Special Steel Production: It is used in the production of steel grades that require low sulfur and oxygen content, such as railroad steel and bridge steel, to ensure their high strength and toughness.
The addition of calcium silicate cored wire can significantly improve the plasticity, toughness and fatigue resistance of steel, reduce inclusions and harmful elements in steel, and make it perform better in various demanding industrial applications.
