Abstract
An apparatus for injecting gas into a metallurgical vessel is disclosed. The apparatus includes a gas flow duct, an elongate central tubular structure extending within the gas flow duct, a plurality of flow directing swirl vanes disposed about the central tubular structure, and cooling water passages within the central tubular structure. The forward end of the central structure has a nose portion that includes a domed outer shell, an inner component disposed within the outer shell and formed with an internal nozzle to receive water from the cooling water passages and to direct that water in a jet against the inner surface of the outer shell to produce an outwardly and backwardly fanning flow of water around the inner surface of the outer shell.
