ABSTRACT:
A purging device for use in metal processing includes a shell, a body and a plurality of gas delivery tubes. The body comprises a refractory material and the tubes are disposed therein. Each tube has at least two passageways extending therethrough. The body with the tubes disposed therein is placed in the shell such that there is a gap between a portion of the body and the shell. An inlet allows the device to be attached to a lance, ladle or similar apparatus. Gas flows through the inlet, into the shell, through the passageways in the tubes and into the molten metal. In this manner, gas is delivered through the purging device through a plurality of passages that are arranged in discrete groups.
