ABSTRACT:
A device for introducing gas into a mass of molten metal from a location in the side wall of a vessel for creating a stirring action therein has a refractory body having a plurality of passageways transversely thereof, the refractory body being positioned in the safety and working refractory lining of a ladle or the like so as to communicate with the interior thereof and molten metal therein. Tubular members positioned in or communicating with the passageways extend from the refractory body and upwardly to a chilling device which in turn communicates with a gas delivery tube through which a desirable supply of gas, such as argon, is delivered under pressure for introduction into the molten metal.
