ABSTRACT:
A solid non-permeable refractory plug of an inverted frusto-conical shape has a spaced metal jacket and is located in an inverted frusto-conical shaped cavity in a pocket block incorporated in the normal refractory lining of a ladle to provide a structure through which gas can be introduced into the molten metal in an unusually large annular stream. A tubular body member is attached to the smaller lower end of the refractory plug and metal jacket and extends downwardly through the refractory lining of the ladle and an opening in the bottom of the ladle to which it is secured by a fastener and through which gas is introduced into the ladle. The large annular stream of gas formed by the device results in an improved stirring action in the molten metal and displaces molten metal that would otherwise tend to flow into the device and close the gas passageway. The device is inserted into the pocket block by moving it downwardly through the ladle and the pocket block.
