CaFe cored wire is a metallurgical material widely used in the steel smelting process, especially for micro-alloying and molten steel deoxidation and desulfurization treatment in the steelmaking process. Core wire is a composite material, usually made of calcium metal and iron powder, with a steel skin wrapped around the exterior.
CaFe cored wire composition and structure
- Core composition: a mixture of calcium and iron powder.
- External wrapping: steel skin or other metal materials as a protective layer to prevent the core component from reacting with oxygen in the air.
- Deoxygenation: Calcium is a strong reducing agent, which can effectively remove the oxygen in the steel, reduce the oxygen content in the steel and improve the purity of the steel.
- Desulfurization: Calcium reacts with sulfur to generate calcium sulfide, thus reducing the sulfur content in steel and improving the mechanical properties and ductility of steel.
- Refine grain: By adding calcium, it can refine the grain, improve the organization structure of steel, and improve the mechanical properties.
- Improve steel fluidity: Calcium can reduce the inclusions in steel, enhance the fluidity of steel, and reduce the defects during pouring.
CaFe cored wire application
Calcium-iron cored wire is mainly used in the production of highly demanding steel grades, especially in the field of high purity steel and special alloy steel, such as:
- Mild and ultra-low carbon steels
- High strength structural steels
- special purpose alloy steels
caFe cored wire advantages
- Precise control: The amount of calcium and iron added to the liquid steel can be precisely controlled by the cored wire, realizing precise alloying of trace elements.
- Reduced Pollution: Compared with the traditional joining method, the core wire can reduce material loss and environmental pollution.
- Easy process: Relatively easy to operate, the process is more stable by adding directly into the steel water through automated equipment.
The use of Calcium-Iron cored wire can significantly improve the quality of steel, especially for the production of high-performance steel is very critical.
