Product Introduction
Products Description
Calcium carbide cored wire is a metallurgical auxiliary material specifically designed for efficient calcium treatment in molten steel. It consists of high-purity calcium carbide powder encased in cold-rolled steel strip, ensuring a stable addition of calcium to the molten steel while minimizing oxidation losses. This technology significantly improves calcium recovery rates and enhances the purity of the steel.
The calcium carbide-cored wires produced by Enhao Alloy feature uniform composition and an optimal diameter, enabling the precise addition of calcium carbide to molten steel to facilitate effective deoxidation, desulfurization, and inclusion modification. This improves the performance of your steel products while reducing your costs.

Product Applications
1. Secondary Refining for Desulfurization and Deoxidation
During LF, RH refining, or vacuum refining, calcium carbide cored wire reacts rapidly to reduce oxygen and sulfur content in molten steel, effectively improving composition and laying a solid foundation for subsequent continuous casting or rolling.
2. Molten Steel Modification Before Continuous Casting
When introduced late in the melting process, calcium carbide modifies inclusions, transforming elongated or angular inclusions into spherical or compact particles. This enhances molten steel cleanliness, reduces surface defects and internal porosity in continuous cast slabs, and ensures finished steel product quality.
3. Production of High-Purity Steel Grades
When manufacturing bearing steel, high-strength structural steel, or alloy steels with stringent inclusion control requirements, calcium carbide cored wire stabilizes molten steel quality, minimizes composition fluctuations, and guarantees mechanical properties and machinability.
4. Cost and Operational Advantages
The cored structure reduces calcium carbide burn-off, offering greater efficiency and more stable absorption rates compared to loose powder or lump calcium additions. On-site operation is more convenient, compatible with automatic feeding equipment, reducing dust splatter and improving production environment cleanliness.
5. Adaptability to Multiple Steelmaking Processes
Whether in electric arc furnaces, converters, secondary refining, or continuous casting pretreatment, calcium carbide cored wire can be flexibly applied according to steel grade and process requirements, enabling rapid, precise calcium supplementation and molten steel modification.
