続鋳造用浸漬ノズルにおいて、前記浸漬ノズル本
体の内径断面積を下方程減少するように形成する
と共に前記溶鋼流出開口部も浸漬ノズル本体の下
方になる程その開口部が減少するような形状に構
成してなることを特徴とする浸漬ノズル。 In a continuous casting immersion nozzle in which a molten steel outflow opening is bored at the bottom of the nozzle body, the inner diameter cross-sectional area of the immersion nozzle body is formed to decrease as it goes downward, and the molten steel outflow opening is also located below the immersion nozzle body. An immersion nozzle characterized in that it is configured in such a shape that its opening gradually decreases.
