Abstract
PURPOSE:The titled conveter tuyere, which can effectively save the flow rate of protective medium fluid, within a range to keep the pressure without lowering the cooling effect, by passing the protective medium through the pore of the porous brick surrounding the oxidizing gas injection nozzle, instead of introducing the protective medium into the gap of the double tube. CONSTITUTION:The conveter tuyere is constituted of the oxidizing gas injection nozzle 1, installed in the direction to pierce the liner brick 4 of the converter, the porous brick 2 surrounding this nozzle 1, the refractory material layer 3 for air tight coating this brick 2, and the iron shell 5. Hereupon, especially around the nozzle 1, the porous brick 2 is arranged so as to surround the nozzle 1 over the range of at least the working brick 4a of the liner brick 4. Besides, the length of the brick 2 is made equal to or longer than the thickness of the brick 4a; hereby, the path for the protective medium (Kerosene, for instance) is secured over the period of life of the brick 4a until it is worn away. Furthermore, after the brick 4a is worn away, the brick 4a is repaired to regenerate, and at same time, the tuyere is also renewed. In the illustration, 4b shows the permanent or semipermanent brick, and 6 shows the imaginaryline for the wear limit of the working brick 4a.
