鋳片となる。[Prior Art] Conventionally, in continuous steel casting, a cylindrical immersion nozzle is installed at the molten steel outlet part of the bottom wall of a tundish, and molten metal is continuously injected into the mold from the opening at its tip, for example. do. A dummy bar is inserted from the bottom of the mold, and the upper end of this dummy bar forms the bottom of the mold before the slab is pulled out. Then, when molten steel is poured into the mold and the molten steel in the mold reaches a predetermined height, the dummy bar is continuously pulled downward by pinch rolls holding the dummy bar. In this case, since the mold is water-cooled, the molten steel is cooled by this mold,
Furthermore, cooling water is sprayed downstream of the mold and solidifies.
It becomes a slab.

れた溶鋼中の不純物を吸着する役割を有している。On the other hand, in a steady state, the tip of the submerged nozzle is immersed in the molten steel in the mold, and in this state, molten steel is injected to prevent the molten steel from coming into contact with the outside air and being oxidized. In addition, powder is suspended on the surface of the molten steel in the mold.
This powder prevents oxidation of the molten steel in the mold. This powder is further melted by the injected molten steel flow, flows between the mold and the solidified shell, and acts as a lubricant between them, and also acts as a lubricant between the molten steel and the molten steel supplied to the mold by the stirring force of the injected flow. It has the role of adsorbing impurities.

鋼湯面近傍で溶鋼のよどみが発生してしまう。[Problem to be Solved by the Invention 1] However, the portion of the outer wall of the immersion nozzle that comes into contact with the molten steel in the mold is severely eroded by the molten steel and powder as the immersion time increases. In particular, in the case of multiple casting, since the casting process takes a long time, the immersion nozzle is moved three or four times in the direction of increasing immersion depth during casting to change the part that contacts the molten steel surface. Attempts have been made to avoid erosion, but as the immersion depth of the immersion nozzle increases,
The stirring power of the molten steel flow discharged from the immersion nozzle becomes weak, and stagnation of the molten steel occurs near the molten steel surface.

在物も鋳片の内部欠陥の原因となってしまう。When such stagnation of molten steel occurs, the temperature of the molten steel decreases near the molten metal surface, and the powder is insufficiently melted, resulting in poor powder flow. Under these conditions, heat removal from the molten steel is limited due to uneven powder flow.
As a result, the molten steel solidifies non-uniformly, defects are formed near the surface of the slab, and unsolidified powder is drawn into the molten steel, resulting in the formation of inclusion defects inside the slab. Furthermore, due to stagnation of the molten steel, inclusions in the molten steel are not sufficiently floated.
Inclusions in the molten steel are not sufficiently adsorbed by the powder, and these inclusions also cause internal defects in the slab.

It is an object of the present invention to provide a continuous casting method that does not cause stagnation on the molten steel surface in a mold and can produce slabs with few defects.

A continuous casting method in which molten metal in a tundish is continuously injected into a mold from an opening in the tundish for continuous casting, the method comprising forming a hole in the peripheral wall of the immersed part of the immersion nozzle, and injecting the molten metal supplied from the tundish into the opening. and the hole.

Since the molten metal flows through the immersion nozzle, the molten steel pressure therein becomes lower than the pressure outside the immersion nozzle, and the molten metal around the hole is sucked into the immersion nozzle. As a result, the molten metal flows within the mold, and stagnation of the molten metal flowing onto the molten metal surface in the mold can be eliminated.

FIG. 1 is a sectional view showing equipment for carrying out this embodiment. The tandish 1 is composed of a main body 2 made of refractory bricks and an iron shell 3 covering the main body 2, and molten steel 4 is stored inside the main body 2. A molten steel outlet 5 is formed in the bottom wall of the tundish 1, and a sliding nozzle 6 for adjusting the flow rate of molten steel is installed in this molten steel outlet 5.

る。A mold 20 is disposed below the tundish 1, and the molten steel 4 in the tundish 1 is injected into the mold 20 through the immersion nozzle 10. The mold 20 is made of copper and has a cylindrical shape, and cooling water is circulated inside the mold.

４回繰返す。When the molten steel level in the mold 20 rises due to the injection of the molten steel 4 from the tundish 1 and reaches a steady state of a predetermined height, the tip portion including the hole 11 of the immersion nozzle 10 is inserted into the molten steel in the mold 20. It is meant to be immersed in. In this case, the center of the hole 11 of the immersion nozzle 10 is first immersed in a predetermined position below the scene, and after a predetermined period of time has passed after the start of casting, the immersion depth of the immersion nozzle 10 is increased by an appropriate amount, and then the immersion depth of the immersion nozzle 10 is increased by an appropriate amount, and then the immersion depth of the immersion nozzle 10 is increased by an appropriate amount. After the lapse of time, increase the immersion depth and repeat this 3 to 4 times.

を清浄化する。A portion of the molten steel in the mold 20 adjacent to the mold is cooled by the mold and solidified to form a solidified shell 21 . Further, powder 22 is suspended on the surface of the molten steel in the mold 20, and this powder 22 prevents oxidation of the molten steel in the mold 20, and also melts the inner wall of the mold 20 and the solidified shell 22. Flows between the two to improve lubricity between them. Furthermore,
Inclusions in the molten steel supplied into the mold 20 are adsorbed to clean the molten steel.

flows towards. Molten steel 4 passed through the immersion nozzle 10
is discharged into the mold 20 from the opening 12. In this case, since molten steel flows through the immersed nozzle 1°, the pressure inside the immersed portion of the nozzle 10 is lower than that outside.

、溶鋼を一層清浄化することができる。Since the hole 11 is formed in the part of the immersion nozzle 10 immersed in the molten steel, the molten steel around the hole 11 on the outside of the immersion nozzle 10 flows through the hole 11 to the immersion nozzle 1 with a low ambient pressure.
It is attracted to the inside of 0. As a result, molten steel flows as shown by arrows 30 and 31 within the mold 20. For this reason,
Even if the immersion depth of the immersion nozzle is large, the molten steel near the molten metal surface in the mold 20 flows, and stagnation of the molten steel at the molten metal surface in the mold 20 can be eliminated. Therefore, it is possible to cast without lowering the temperature of the molten steel near the molten metal surface, and the powder 21
It is possible to suppress the occurrence of defects in slabs due to insufficient melting. In addition, this molten steel flow improves the ability to float and separate inclusions contained in the molten steel supplied to the mold, and the floating inclusions are easily adsorbed by the powder 21, so that the molten steel can be further cleaned. I can do it.

In Figure 2, the horizontal axis shows the molten steel temperature near the surface of the spinning mold as an addition to the molten steel solidification temperature, and the vertical axis shows the immersion depth of the immersion nozzle, and the relationship between these is plotted. FIG. In the figure, circles indicate the case of casting according to this embodiment, and triangle marks indicate the case of casting according to the conventional method. Further, black areas indicate slab defects caused by insufficient melting of powder, and white areas indicate slab defects in which no such defects occurred. As shown in FIG. 2, when casting was performed by the conventional method, as the immersion depth increased, the temperature of the molten steel in the vicinity of the spot decreased, and the above-mentioned slab defects occurred when the immersion depth was 120 mm or more. On the other hand, in the case of this example, even when the immersion depth of the immersion nozzle was 120 mm or more, the molten steel temperature near the scene was relatively high, and the slab defects as described above did not occur.
