摘要

COMPOSITE METAL ARTICLE CONTAINING ADDITIVE AGENTS AND METHOD OF ADDING SAME TO MOLTEN METAL A composite wire-like structure for adding relatively volatile metallic agents such as magnesium to molten ferrous metal comprising an inner core of said metallic agent, an outer sheath of ferrous metal, and in insulating material disposed between said sheath and said core in surrounding relation to the core. A method is also provided for adding said agent to molten ferrous metal comprising the steps of continuously feeding the composite wire-like structure containing said agent at a controlled rate sufficient to provide a desired amount of said agent in the molten metal.
