Calcium Silicon Cored Wire For Stainless Steel Refining

Calcium Silicon Cored Wire for Stainless Steel Refining, made with a low-carbon steel strip as the outer sheath and coated with high-purity calcium silicon alloy powder, is a core functional material in stainless steel ladle refining (LF/VD/VOD processes). It enables precise deoxidation, desulfurization, inclusion modification, and steel purification, significantly improving the purity and yield of stainless steel.

Austenitic Stainless Steel (304, 316, etc.): Deoxidation, desulfurization, inclusion modification, improved corrosion resistance and processing performance, reduced surface defects.
Ferritic Stainless Steel (430, etc.): Improved slag fluidity, reduced Cr₂O₃ loss, optimized steel purity, increased product yield.
High-end Stainless Steel Products: Such as food-grade stainless steel, medical-grade stainless steel, stainless steel pipes/plates, precise control of inclusion size, ensuring product mechanical properties and safety.
Stainless Steel Continuous Casting Process: Improved molten steel fluidity, reduced nozzle blockage, improved continuous casting billet quality, reduced subsequent processing costs.

Henan Tieyao Trading Co., Ltd.has always adhered to the corporate culture of "people-oriented, scientific management, civilized and harmonious, and pursuit of excellence". With the spirit of active learning, diligent thinking, courageous practice, and good at summarizing, it strives to improve its own quality, promote professional management, and put corporate development first.

Q1: What are the advantages of calcium-silicon cored wire compared to traditional block calcium-silicon alloy?

A1: Compared to traditional block calcium-silicon alloy, our calcium-silicon cored wire has a 30%-50% higher alloy yield, more precise composition, and avoids element loss and waste. The wire feeding operation is highly automated, safe, and convenient, allowing for deep internal reaction in molten steel for more thorough purification, while reducing overall production costs. It is especially suitable for the refining needs of high-purity steels such as stainless steel.

Q2: Can you customize products according to our stainless steel refining process?

A2: Yes! We have a professional R&D and production team that can customize wire diameter, composition, length, and packaging according to your stainless steel grade (304, 316, 430, etc.), refining equipment (converter, electric furnace, AOD furnace), and process requirements, ensuring the product perfectly matches your production needs. We also provide one-on-one technical guidance to guarantee the best results.

Q3: How should the product be stored and used?

A3: Store in a dry, ventilated warehouse, avoiding moisture and rain to prevent oxidation of the core powder and its impact on performance. When in use, the cored wire is fed into the molten steel at a depth of 1.5-2.0m below the surface using an automated wire feeding device. The feeding speed is 3-5m/s and can be continuously adjusted. After feeding, the wire is allowed to settle for ≥8 minutes to ensure that inclusions float to the surface. Specific parameters can be adjusted according to your process requirements.
