摘要 |
A gas feed pipe connecting screw (1) for a continuous casting nozzle (11) is disclosed. The screw (1) is mounted to the continuous casting nozzle (11) formed with an axially extending ring-shaped slit (13) substantially concentric with a nozzle bore (12). The screw (1) connects to the nozzle (11) a gas feed pipe blowing a gas into the slit (13). The screw (1) includes a screw body (2) having a gas feed hole (4) formed through substantially its central portion, a flange (3) fitted into a mounting hole (14) formed in a side wall of the continuous casting nozzle (11), a male thread (6) engaging a first female thread (16) formed in the mounting hole (14), and a second female thread (5) formed in the gas feed hole (4) for connection of the gas feed pipe (18). The flange (3) has a detent corner (3a) engaging mortar (17) filling the mounting hole (14) after having been fitted into the mounting hole (14). |
