Silicon Calcium Wire & Calcium Iron Wire in Stock – Reliable Cored Wire Solutions for Steelmaking
Silicon calcium wire and calcium iron wire are widely used cored wire products in modern steelmaking and foundry processes. By injecting active elements such as calcium, silicon, and iron directly into molten steel, these wires significantly improve steel cleanliness, inclusion modification, and metallurgical efficiency.
ZhenAn supplies silicon calcium wire and calcium iron wire in stock, ensuring fast delivery, stable quality, and reliable performance for global steel plants and industrial B2B customers.
What Is Silicon Calcium Wire?
Silicon calcium wire (CaSi wire) is produced by filling a low-carbon steel sheath with calcium–silicon alloy powder. It is mainly used as a deoxidizer, desulfurizer, and inclusion modifier during secondary steel refining.
Key Functions of Silicon Calcium Wire
Modifies alumina inclusions into liquid calcium aluminates
Improves steel fluidity and castability
Reduces nozzle clogging during continuous casting
Enhances mechanical properties and steel cleanliness
What Is Calcium Iron Wire?
Calcium iron wire (CaFe wire) consists of a steel sheath filled with calcium–iron alloy powder. It is designed to introduce calcium more gently and stably into molten steel.
Key Functions of Calcium Iron Wire
Efficient calcium recovery
Improved desulfurization performance
Stable calcium absorption
Reduced oxidation loss
Calcium iron wire is especially suitable for carbon steel, low-alloy steel, and special steel grades.

Advantages of Silicon Calcium Wire & Calcium Iron Wire
High Calcium Utilization Rate
Cored wire injection allows calcium to enter molten steel below the slag layer, reducing oxidation loss and improving recovery.
Improved Steel Quality
Both wires effectively modify inclusions, reduce sulfur content, and enhance steel cleanliness, leading to better mechanical properties.
Stable and Safe Operation
Wire feeding ensures precise alloy addition, safer handling, and consistent results compared to traditional lump additions.
