ABSTRACT:
A device for introducing gas into a mass of molten metal in a vessel for creating a stirring action therein by way of an apertured block in the refractory lining of said vessel. The device communicates with an opening in the vessel, the opening being sized to permit the introduction and/or exchange of a device core upwardly into the apertured block from the outside bottom or wall of the vessel. The core has a plurality of passageways therethrough and preferably incorporates a conical sleeve thereabout and an apertured spacer therebelow through which a gas supply extends. A removable closure for the opening in the outside bottom or wall of the vessel normally supports the replaceable stirring device when the vessel is in use.
