Calcium Silicon Cored Wire
Calcium silicon cored wire is a metallurgical additive used to introduce calcium and silicon into molten steel during the smelting process. This product is supplied by Ronghai Supply Chain Co., Ltd. from Haidong Industrial Park in Qinghai Province, China. The wire’s outer steel sheath protects the calcium silicon powder inside, ensuring controlled release and efficient alloying in electric arc furnaces or ladle treatments. The core material is tailored to specific smelting requirements, with diameter and composition adjusted for the target steel grade and process conditions.
The alloy composition typically includes 28-32% calcium and 58-62% silicon, with trace elements like iron and aluminium to stabilise the reaction. The steel sheath is standard cold-rolled low-carbon steel, offering sufficient ductility for feeding through wire feeders at typical speeds of 80-150 m/min. Calcium silicon cored wire enhances steel cleanliness by deoxidising and desulphurising the melt, while also modifying non-metallic inclusions to improve mechanical properties in the final product.
Steelmakers use this wire in the production of high-strength low-alloy steels, pipeline steels, and automotive grades where inclusion control is critical. Buyers source it for its consistency in chemical delivery and ease of handling compared to lump additives. Trade terms such as packaging in 1-tonne coils, MOQ, and lead times should be confirmed with Ronghai Supply Chain Co., Ltd., as these are customised per order. The product is suitable for bulk imports, with logistics often arranged via Qinghai’s rail and port networks for delivery to international steel plants.

Sourcing Calcium Silicon Cored Wire from Ronghai Supply Chain Co., Ltd. - China Import Guide
Before ordering, verify the exact calcium and silicon percentages in the core material, as these directly impact deoxidation and inclusion modification. Confirm the steel sheath’s carbon content to ensure it does not introduce unwanted elements into the melt. Request a certificate of analysis for the wire’s composition to match your steel grade requirements.
Logistics for bulk imports should account for coil weight and dimensions, as 1-tonne coils require appropriate handling equipment. Confirm lead times and Incoterms with Ronghai Supply Chain Co., Ltd., as these vary based on order size and destination. For international shipments, check if the supplier arranges transport to Qinghai’s nearest port or rail hub.
Quality checks should include visual inspection of the wire’s sheath for defects and verification of coil weights. Request documentation such as mill test certificates for the core material and sheath. For critical applications, conduct a trial run to validate the wire’s feeding performance and its effect on steel cleanliness before full-scale production.
