<p>A ladle shroud (40) having a co-pressed porous ring (50) for the introduction of an inert gas at the sealing joint between the ladle shroud and a mating ladle collector nozzle. The dense body (42) of the ladle shroud and the co-pressed porous ring are of similar carbon-bonded graphite refractory grain compositions and have similar carbon containing binder systems to improve the bond between the ring and body components. The dense body further includes a continuous, integral ledge portion (52) which, abuts a tip surface of the porous ring to seal the top of the ring against unwanted inert gas leakage.</p> |
