ABSTRACT:
A tuyere for use in a metallurgical vessel comprising a first pipe adapted to be affixed to the wall of a metallurgical vessel and having a first end extending through the refractory lining of the vessel and a second end extending outwardly therefrom. A gas inlet member is affixed to the second end of the pipe and the second pipe is affixed to the gas inlet member and extends inwardly through the first pipe. The outer diameter of the second pipe is smaller than the inner diameter of the first pipe to provide a gap there between. Means are provided between the first and second pipes to maintain them in spaced-apart relation and the interior of the first pipe is filled with a material such as refractory.
