Cored wire
NextIntroduction
Cored wire is a composite material composed of a metallic sheath surrounding a core of alloying elements or other materials. It is primarily used in steelmaking and foundries for precise alloying and refining processes. The top producers of cored wire are China, India, and the United States. Cored wire helps improve steel quality by introducing materials like calcium, magnesium, or carbon into molten steel.

How is cored wire produced?
Cored wire is produced by encasing a core of alloying elements such as calcium, magnesium, or carbon within a metal sheath, usually steel. The sheath is formed into a tube, and the core material is filled inside. The wire is then coiled and packaged for use in steel mills and foundries, where it is added to molten steel for precise alloying and refining.
What is cored wire used for?
Cored wire is a consumable product used in metallurgical processes, primarily in steelmaking and foundries, to introduce specific alloying elements or deoxidizers into molten metal. The main uses of cored wire:
- Alloying and Refining: Cored wire is used to add alloying elements such as calcium, aluminium, titanium, and magnesium to molten steel or cast iron. These elements help improve the mechanical properties of the steel or iron, like strength, ductility, and resistance to corrosion.
- Deoxidation: In steelmaking, cored wire is employed to remove oxygen from the molten steel, reducing impurities and improving the quality of the final product. Elements like aluminium or calcium are commonly introduced for deoxidation purposes.
- Inclusion Modification: Cored wire helps modify non-metallic inclusions in the steel. For instance, calcium treatment via cored wire can change the shape and distribution of sulphides, making the steel more resistant to cracking and improving its overall toughness.
- Sulphur Control (Desulfurization): Cored wire can be used to add materials like calcium or magnesium, which react with sulphur in the molten metal to form sulphides. These sulphides float to the surface, making it easier to remove sulphur from the steel.
- Nodularization in Cast Iron: In ductile iron production, cored wire is used to add magnesium, which helps form spherical graphite nodules in the iron, enhancing its ductility and strength.
- Refining Slag Control: Certain types of cored wires can be used to influence slag composition in the refining process, ensuring that it is more fluid and can better absorb impurities.
These processes are key to improving the quality of steel or iron, and the controlled introduction of elements through cored wire ensures precision in metallurgy.
