What is Calcium Iron Cored Wire?
Calcium iron cored wire, also known as calcium iron alloy cored wire, is a type of alloy cored wire produced by mixing metal calcium with iron powder in a specific ratio and cladding the mixture with a cold-rolled low-carbon steel strip. It is widely used in calcium treatment of pure steel (such as low carbon steel, ultra-low carbon steel, and low silicon steel) due to strict requirements of iron and steel enterprises on inclusions.
Calcium Iron Cored Wire Specifications
| Type | Main Composition (%) | Inside Powder Weight (g/m) | Steel Strip Thickness (mm) | Cored Wire Diameter (mm) |
| CaFe | Ca: 28-35 | 230-250 | 0.4±0.2 | 13-13.5 |
Why Use Calcium Iron Cored Wire?
The invention of calcium iron cored wire solves the problem that traditional calcium-iron alloy deoxidizers cannot reach the deep part of molten steel for reaction. Calcium is a strong deoxidizer, but it has low specific gravity and melting point, which easily generates bubbles at high temperatures. Simply adding calcium metal particles or powder into the refining furnace will cause rapid combustion, failing to penetrate into the deep molten steel and achieve ideal purification effect.
The core layer of calcium iron cored wire is composed of 28%-35% calcium particles and 65%-72% iron powder. Iron increases the specific gravity and melting temperature of calcium particles, slowing down calcium evaporation and reducing costs. Meanwhile, the weight of iron powder accelerates the sinking speed of the cored wire, allowing it to quickly reach the ideal reaction position in molten steel.
Advantages of Calcium Iron Cored Wire
- Improve Steel Performance：As a common deoxidizer in molten steel refining, it avoids the formation of strip sulfide inclusions, reducing the anisotropy of steel and improving product quality.
- Multi-functional Purification：Fed into the deep molten steel by a wire feeder, it realizes deoxidation, desulfurization and inclusion removal simultaneously, ensuring molten steel purity.
- Cost-saving & Stable Composition：It fine-tunes steel composition, improves the yield of metals and rare earth elements, reduces the addition of precious metals, and lowers refining costs.
