Cored Wire
Cored Wire: Precision Alloying for Superior Steel Quality
The growing demand for high-performance steel in sectors such as railways, defense, construction, and automotive has made it essential to achieve precise alloying at competitive costs. One of the key challenges in secondary (in-ladle) metallurgy is the controlled addition of light, reactive, or easily oxidized elements to molten steel—while ensuring high and consistent recovery rates.
Cored wire injection offers the most efficient solution to this challenge. By injecting alloying elements deep into the ladle at controlled speeds, oxidation losses are minimized, vaporization is delayed, and the elements have more time and contact area to react with the molten steel—leading to improved efficiency and metallurgical performance.
The low-carbon steel sheath of the wire protects the core material from moisture and atmospheric oxidation during storage and handling, as well as from slag during injection. Additionally, the sheath provides structural rigidity, enabling precise control over the wire’s immersion depth by adjusting feeding speed and sheath thickness. This allows for accurate and reproducible alloying.
We manufacture and supply a wide range of cored wire in standard diameters of 9mm, 13mm, and 16mm, tailored to meet diverse steelmaking requirements.
