Abstract: A tuyere for a metallurgical vessel comprising a solid metal tuyere body with a central gas feed bore. The gas feed bore contains at least one gas feed pipe. The tuyere body also has at least one water-cooled bore between the outer wall of the tuyere body and the gas feed bore. A water-cooled bore has a water passage for circulating water therethrough. A water cooling header with separated water inlet and outlet is attached to the tuyere body external to the metallurgical vessel. A water passage is provided for a flow of water from the water inlet through the water passage in the water-cooled bore to the water outlet. The cooling capacity of the tuyere is sufficient to cause the formation of a protective encrustation on the end of the tuyere, and to effectively reduce erosion and chemical reaction of the tuyere material and the vessel wall.
