Pure Calcium cored wire is a metallurgical component made up of a metal Calcium core and an outer sheath composed of cold-rolled strip steel. It is often used as an inclusion modifier, desulfurizer and deoxidizer for steelmaking. Cored wires in steelmaking allow manufacturers to achieve a higher calcium content as well as better metallurgical performances. Moreover, the sheath of steel helps prevent the cores from falling out during the process.
Wire feeding machine injects liquid steel with the encapsulated calcium core. This method of introducing Calcium is more efficient than lump additions and the high reactivity ensures maximum efficiency in deoxidation and desulphurization.
The cored wire has a significant advantage in that it prevents the nozzle from becoming blocked due to alumina(AL2O3) inclusions, which are a by-product of aluminum deoxidation. It is also possible to add large amounts of Calcium without causing oversaturation. This significantly reduces the time and effort needed to manage impurity management in the steel plant.
Moreover, cored wire allows a more even distribution of graphite to the cast iron. It also reduces the blockage problems at steel ladle outlets. It also improves cast iron quality and reduces total production costs. Additionally, it increases melting point and corrosion resistance of cast iron.
The metallurgical cored steel wire must be stored and handled with care to minimize any challenges or risks. It must be properly protected and kept dry to prevent moisture or contamination. In addition, it must be kept away from any flammable materials and must not come into contact with any other substances that could react with the core. Furthermore, the cored wire should be wrapped in a protective film to prevent it from getting wet during storage and transportation.
