  • Cored wire with particulate material
    Patent number: 11525168
    Abstract: A cored wire for refining molten metal includes a reactive core material that is in the form of a solid rod. A non-reactive particulate material radially surrounds the solid core material, and an exterior metal jacket radially surrounds the particulate material. The particulate material may include wood or other material that when introduced into the molten metal, undergoes thermal decomposition to release carbon dioxide, hydrocarbons, or combinations thereof as a shroud around the core material.
    Type: Grant
    Filed: January 6, 2021
    Date of Patent: December 13, 2022
    Assignee: P.C. CAMPANA, INC.
