Revolutionize Your Steelmaking with Advanced CaSi Cored Wire Technology

In the world of secondary metallurgy, precision and efficiency are crucial. Calcium Silicon (CaSi) cored wire has transformed how modern steelmakers approach ladle furnace treatment. This innovative composite material features carefully calibrated calcium-silicon alloy powder enclosed in a thin, cold-rolled steel sheath. It enables direct, controlled injection of reactive calcium deep into the molten steel bath, ensuring optimal interaction with oxygen and sulfur while minimizing waste through oxidation or vaporization.

Modern CaSi cored wire is engineered to exacting specifications to ensure consistent and reliable performance

Parameter   Core Composition	Typical Specification                           Importance in Steel Refining
	Calcium:28-33%; Silicon:55-65%	Provides the necessary chemical agents for deoxidation, desulfurization and most critically, inclusion  modification.
	0.25-0.40   mm	Offers optimal protection for the reactive core against moisture and air, while maintaining flexibility for smooth feeding through automated systems.
Standard                                  Caters to different treatment intensities and ladle sizes; custom diameters               9    mm,13    mm,16mm Diameters                                                  are available for specialized applications.
Powder Density		Guarantees uniform and predictable release of calcium during the wire feeding process, leading to consistent treatment results.

Why Choose Modern CaSi Cored Wire?

Our CaSi cored wire is manufactured to meet strict specifications, delivering consistent performance and measurable metallurgical benefits:

• Improved Inclusion Modification: Achieve 40–60% better efficiency compared to traditional powder injection methods. Abrasive alumina (Al₂O₃) inclusions are transformed into soft, globular calcium aluminates that enhance machinability and final product quality.

• Higher Calcium Yield: With 18–25% of added calcium retained in the steel—significantly more than the 8–15% from conventional methods—our cored wire ensures effective treatment with less material.

• Reduced Consumption: Modern facilities use only 0.8–1.2 kg of CaSi cored wire per ton of steel, compared to 1.5–2.0 kg/ton required by older technologies.

CaSi Cored Wire Engineered for Reliability and Performance

At Anyang Hongshun, we combine full automation with rigorous quality control. Our production lines monitor thirteen key parameters in real time to guarantee every meter of wire meets the highest standards. Each coil is individually tested for:

• Tensile strength (minimum 250 MPa)

• Elongation characteristics

• Powder retention to prevent leakage

Additionally, our proprietary coating technology offers superior corrosion resistance, extending the product’s shelf life to 18 months without performance loss—even in demanding storage conditions.
