Calcium Silicon Cored Wire （CaSi Wire） Production Process

Calcium silicon cored wire serves as a vital alloying agent in steel production, contributing to the refinement of steel’s composition and properties. The efficiency gains facilitated by calcium silicon cored wire are substantial. Its seamless integration into steelmaking processes expedites deoxidation and alloying, reducing cycle times and resource consumption. This translates to increased throughput, reduced energy expenditure, and ultimately, cost savings for steel manufacturers.

So its production involves a series of precise steps to ensure quality and consistency in the final product.

1. Raw Material Acquisition

The production process begins with the acquisition of high quality raw materials.

Calcium silicon cored wire mainly used calcium silicon powder as the core powder filling material. mix silicon and calcium in proportion and crush into 0-3mm powder for use.

Calcium silicon powder is used as a deoxidizer and desulfurizer in steelmaking, So these materials undergo rigorous quality control measures to ensure they meet the required specifications.

2. Cored wire sheath preparation

A steel strip sheath is selected as the wire material for the cored wire. steel strip as a container for the calcium silicon alloy powder, the thickness is usually 0.35-0.5mm. Before filling, the core wire undergoes surface cleaning processes to remove any impurities or contaminants that could compromise the integrity of the final product.

3. Alloy Filling

The core wire is then filled with a precise blend of calcium and silicon powders or granules. The proportions of these elements are carefully controlled to achieve the desired alloy composition. The filling process requires precision to ensure uniform distribution of the alloy within the core wire.

4. Encapsulation

Through the cored wire machine, wrap calcium silicon powder into the steel strip at a uniform speed. Once filled, the core wire is encapsulated with sheath material, and its Winding into coils. This encapsulation serves multiple purposes, including preventing oxidation of the alloy during handling and transportation, as well as ensuring the integrity of the cored wire.

The main cored wire diameters are 13mm and 9mm.

5. Quality Control and Testing

Throughout the production process, rigorous quality control measures are implemented to verify the integrity and composition of the cored wire. Various tests, including chemical analysis, tensile strength testing, and visual inspections, are conducted to ensure compliance with industry standards and specifications.

6. Packaging and Distribution

Once production and quality control checks are complete, the finished calcium silicon cored wires are packaged according to Customer requirements.

Conclusion

The production of calcium silicon cored wire is a meticulously controlled process, requiring precision and attention to detail at every step. From raw material acquisition to final packaging, each stage is carefully executed to ensure the production of high-quality cored wires that meet the demanding requirements of the steel industry.
