Optimized Steelmaking: Application Benefits

Calcium Silicide Cored Wire plays a vital role in enhancing steel purity by minimizing undesired elements such as oxygen, sulfur, and non-metallic inclusions. Its accurate injection technology improves process control and product consistency, resulting in higher-quality steel. The wire format enables safe, controlled dosing with minimal waste, supporting efficient large-scale steel production environments.

Technical Specifications and Safe Handling

The product features a robust low-carbon steel sheath and core material with carefully balanced chemical composition and low impurity content (P, S 0.04%). With dimensions of 13 mm diameter and density of 2.22.5 g/cm, cored wire coils can be tailored to customer requirements, commonly weighing 3001000 kg per coil. Proper storage in a dry place extends shelf life up to 2 years.

FAQs of Calcium Silicide Cored Wire:

Q: How is Calcium Silicide Cored Wire used in steelmaking processors?

A: Calcium Silicide Cored Wire is injected into molten steel at approximately 1600C, where it dissolves rapidly. This precise injection allows for targeted addition of calcium and silicon to modify inclusions, facilitate deoxidation, and achieve effective desulfurization in the steelmaking process.

Q: What are the main benefits of using Calcium Silicide Cored Wire?

A: It provides high efficiency in steel refining by improving inclusion removal, lowering sulfur and oxygen levels, and optimizing steel cleanliness. The wire format ensures precision, minimizes handling risks, and reduces alloy wastage, resulting in better steel quality and cost effectiveness.

Q: When should Calcium Silicide Cored Wire be injected into molten steel?

A: This product is optimally injected when the steel temperature reaches around 1600C. Timely injection ensures that the core materials dissolve efficiently and react properly within the molten steel, delivering maximum refining benefits.

Q: Where should the cored wire be stored for maximum shelf life?

A: Cored wire should be kept in a dry, moisture-free environment to preserve integrity. Properly stored, its shelf life is typically between 12 and 24 months, maintaining chemical and physical properties for consistent performance.

Q: What process is used to manufacture Calcium Silicide Cored Wire?

A: Manufacturing involves encasing the precisely measured core alloy (Ca, Si, Fe) inside a tightly sealed low-carbon steel strip. The wire is then formed into spools or coils, with sizes and weights adjusted upon customer specifications, ensuring consistent composition and low impurity levels.

Q: How does the chemical composition of the wire improve steel quality?

A: The significant levels of calcium and silicon allow the wire to facilitate efficient deoxidation and desulfurization, modifying non-metallic inclusions and contributing to cleaner steel with superior mechanical properties and enhanced workability.
