Abstract
A tuyere stock wherein the blast nozzle, which is the downstream section of the stock, is rigidly coupled to the blast tuyere through which the preheated gas is injected into the furnace. The blast nozzle-blast tuyere assembly and a cooling jacket, which is mounted in the furnace wall about the aperture through which the tuyere stock passes, cooperate to define an articulated connection whereby thermally induced distortions of the various components of the stock may be accommodated without interrupting the sealing efficiency of the connection.
