ればよい。In the present invention, regarding the plate brick and the immersion nozzle, it is sufficient that the plate brick satisfies characteristics such as wear resistance, and the immersion nozzle satisfies characteristics such as corrosion resistance and thermal shock resistance, and these materials are not particularly limited. Not done. The plate brick and the immersion nozzle have shapes whose side surfaces all form the same plane, that is, the bottom surface of the plate brick and the top surface of the immersion nozzle do not need to have the same shape. It suffices if it has the shape to be formed.

めである。In the casting nozzle device of the present invention, unlike conventional devices, the tightness between the plate brick and the immersion nozzle does not loosen even when heated during use, and the contact area between the plate brick and the immersion nozzle is larger than that of the conventional device. Therefore, it is possible to prevent problems such as deterioration of steel quality and nozzle clogging due to air adhesion (suction) from the joint between the two. In addition, it is preferable that the area of the upper surface of the immersion nozzle is 1/2 or more of the area of the lower surface of the plate brick. This means that the area of the top surface of the immersion nozzle is 1/of the area of the bottom surface of the plate brick.
This is because if it is less than 2, air is likely to be sucked in.
以下、本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.

。FIGS. 1(a) and 1(b) show a casting nozzle device according to the present invention. As shown in FIGS. 1(a) and (b), the plate brick 1 (sliding plate or lower plate) and the immersion nozzle 2 are formed in such a shape that part of their side surfaces form the same plane. ing. The lower surface of the plate brick 1 and the upper surface of the immersion nozzle 2 are joined via mortar 3, and are fastened by shrink-fitting a metal frame 4 on the side surfaces forming the same plane. plate brick 1
To attach the metal frame 4 on the upper surface, a groove is formed at the part so that the upper surface of the metal frame 4 is lower than the upper surface of the plate brick 1.
