What are cored-wire alloys?

Cored wire is a delivery method long preferred in the steel industry in which the alloy is grounded to a fine size, encapsulated in a sheath of steel, roll-formed into a tube and then wound into a coil. The steel sheath protects the alloy from oxidation and its fine size aids in the integration of the alloy into the molten metal

This cored wire technology, or cored wire injection process, is an ingenious way of adding metallurgical treatment chemical elements in the centre of a liquid iron bath. This process requires the use of an injection device placed vertically or horizontally near the metallurgical treatment site.

This injection device will feed automatically, by considering the mass and the chemical composition of the treated liquid iron volume and the appropriated wire length needed to achieve the required metallurgical treatment.
