Description of the Related Art In continuous casting of steel, when the molten steel comes into contact with air, the quality of the steel deteriorates due to oxidation of the molten steel and an increase in the nitrogen gas content in the molten steel. In order to prevent this, a long nozzle or tundish pipe is placed between the ladle and the tundish, and an immersion nozzle as shown in Fig. 2 is placed between the tundish and the mold. It is widely practiced to lead to dishes and from tundish to mold.

Was prevented from doing so.
However, even when such a long nozzle, tundish pipe or immersion nozzle is used, the airtightness of the material of the casting nozzle itself is reduced during use, and the problems of oxidation and temperature diffusion of molten steel have not been sufficiently solved.

Since carbon is mainly used, carbon components such as graphite, pitch coke and resin coke and silica glass are distributed inside the side wall of the nozzle, and the nozzle is used at a high temperature. In the meantime, they come into contact with the air in the pores on the side walls and undergo oxidation or reduction to gasify,
This is because CO, CO 2 , and SiO volatilize and disappear, which causes the side wall of the nozzle to become porous, thereby reducing the airtightness of the nozzle.

It is an object of the present invention to provide a casting nozzle that prevents gas from being mixed and avoids thermal diffusion of molten steel so that good steel can be cast.

At the same time, the low melting point material such as alumina-silica fiber and rock wool filled therein is softened and melted in the slit. These low-melting substances in the molten state
In the slit of the nozzle side wall, a film is formed on one side wall or both side walls, or exists in various other states, and functions to block external ventilation and to perform heat insulation. Next, in this casting nozzle, the heat insulating property of the nozzle due to the difference in the softening temperature of the low melting point material filled in the slit was examined.

の結果を図４に示した。In the experiment, the nozzle of the present invention shown in FIG. 1 was used, and the cross-sectional size of a substantially central portion in the longitudinal direction of the nozzle was as shown in FIG. That is, the outer diameter was 149 mm and the inner diameter was 77 mm at a substantially central portion in the length direction of the nozzle. The slit is 3mm wide at 13mm from the outside of the nozzle hole.
At the entire periphery of the nozzle hole. The slit is filled with an alumina-silica fiber softening at 700 ° C. in the upper half shown by a solid line in FIG.
An alumina-silica fiber softening at 0 ° C. was filled. The total nozzle length was 580 mm, and the slit length was 340 mm. The temperature of the nozzle was measured at 300 mm from the lower end of the nozzle and at three points A, B and C in FIG. The lower end of the nozzle hole was closed, and molten steel (cast iron) at 1500 to 1700 ° C. was injected from above to perform a pouring side temperature test. The result is shown in FIG.

で、断熱性に実質的な違いのないことが分かる。As is clear from FIG. 4, after the pouring, the temperature of the inner surface A of the nozzle hole rapidly decreases with the passage of time, but the rise in the temperature of the nozzle side portions B and C is small and the melting point is low. It can be seen that there is no substantial difference in the heat insulating properties between the case where a filler having a softening temperature of 700 ° C. is used as the substance and the case where a filler having a softening temperature of 1260 ° C. is used.
