Abstract
An apparatus for injecting gas into a metallurgical vessel is disclosed. The apparatus comprises a gas flow duct, an elongate central tubular structure extending within the gas flow duct, a plurality of flow directing swirl vanes, inflow and outflow cooling water passages within the central structure, and a nose portion provided with one or more water cooling passages. The flow directing vanes are provided with internal water cooling vane passages. In use, water flow is communicated through the vane passages from the water inflow passage in the central structure to the water flow passage in the nose portion of the central structure such that at least some of the inflowing water will pass successively through the vane passages and the nose passage or passages and thence to the outflow passage.
