ABSTRACT:
Apparatus for introducing stirring and refining agents into molten metal in a vessel using a lance having a refractory body and a tube extending inwardly of a first end of the refractory body and terminating inwardly of a second end thereof. A plurality of relatively smaller tubes positioned within the refractory body and communicating with said tube and extending therefrom to the exterior of said refractory body, at least a portion of each of said smaller tubes being formed in a narrow slot-like passageway whereby gas, such as argon, introduced through the tubes and delivered to the exterior of the refractory body will bubble upwardly through the molten metal in a stirring and mixing action including an annular column around the refractory body acting to protect the same from rapid erosion.
