ABSTRACT:
A method of introducing and mixing a refining agent into molten metal in a ladle using a lance having a refractory body shaped to facilitate the positioning of the lance in the ladle is disclosed. Several tubular members are positioned within the lance and communicate with vertically spaced openings in a common plane in a lower side wall thereof communicating with the interior of the ladle and the molten metal therein. Some of the openings are plugged with porous material and others form passageways for the refining agent such as an alloy wire or powder. Gas, such as argon, is introduced through the tubular members having porous plugs and delivered through the porous plugs so as to bubble upwardly through the molten metal around the other openings and the refining agent delivered therethrough in a stirring and mixing action beginning adjacent the bottom of the ladle.
