連続鋳造装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a continuous casting apparatus for steel sheets, in which a partition member is installed between a hot water supply nozzle and a movable mold so that the movable mold does not come into direct contact with a nozzle made of a refractory material.

中１０は凝固殻である。 The advantages of continuous steel plate casting equipment are energy savings and the elimination of rolling equipment during the production of steel plates. A conventional example of this continuous casting apparatus for steel plates is explained with reference to FIGS. 1 and 2. A sump 2 that can store molten steel 1
A refractory nozzle protruding laterally is fixed to the lower part of the nozzle 3, a plurality of movable molds 4 are disposed in close contact with each other on the downstream side of the nozzle 3, and the tip of the nozzle 3 is positioned on the upstream end side. The tip of the nozzle 3 is inserted into the cavity 5 having a rectangular cross section of the movable mold 4 to prevent the molten steel 1 from leaking from between the nozzle 3 and the movable mold 4. A section 3a is provided,
A gap G is formed between the outer surface of the thick portion 3a and the inner surface of the movable mold 4 so that the movable mold 4 can move along the nozzle 3 in the direction D in FIG. Since the gap G has good permeability to the molten steel 1, it should be several tens of microns or less. In the figure, 10 is a solidified shell.

る連続鋳造装置を実用化するうえで重要な問題点
となつている。 As the movable mold 4 moves in the direction of arrow D in FIG. 1, molten steel 1 is sent from the sump 2 into the cavity 5 through the nozzle 3, and the nozzle 3 and the movable mold 4 are exposed to high heat. As a result, the nozzle 3 is distorted and the molten steel that leaks and enters the gap G contacts the movable mold located on the most upstream side and instantly solidifies. Then, the solidified portion moves together with the movable mold 4 and rubs the surface of the nozzle 3, which has become weak due to high heat, and the nozzle 3
is damaged by friction. This is an important problem in the practical application of mobile continuous casting equipment.

め、ノズルは折損する虞れが少ない。 According to the present invention, between the hot water supply nozzle inserted into the cavity and the movable type,
The partition member is arranged so that a gap is formed, and the partition member is fixed to the outside of the cavity so that it does not move together with the movable mold, so when the movable mold moves, the surface of the partition member will not be rubbed. The surface of the nozzle will not be rubbed even if there is a problem. Furthermore, even if a force is applied from the movable type to the partition member, that force is supported by the partition member, and if the partition member is not deflected significantly, the force will not be applied directly to the nozzle, so there is less risk of the nozzle breaking. .

水を供給するための冷却孔８を設ける。 3 and 4 show an embodiment of the present invention, in which a partition member 6 made of steel, for example, is disposed between the nozzle 3 and the movable molds 4, 4' so as to surround the outer periphery of the nozzle 3. The partition member 6 is fixed to a fixed member 7 disposed near the water reservoir 2 so as not to move in the direction of arrow D together with the movable molds 4 and 4', and the partition member 6 can be cooled as necessary. , cooling holes 8 are provided in the partition member 6 for supplying cooling water.

に容易に損傷することはない。 As the movable types 4 and 4' move, the water reservoir 2
Molten steel 1 is sent from the nozzle 3 into the cavity 5. The molten steel in the cavity 5 is transferred to the movable mold 4,
4' and the partition member 6 and the gap G 2 between the partition member 6 and the nozzle 3 ,
Since the nozzle 3 and the partition member 6 are fixed and have no relative speed, the sliding force accompanying the movement of the movable molds 4 and 4' does not act on the nozzle 3. During its movement, the movable dies 4, 4' penetrate the partition member 6 through the molten steel that has penetrated between the partition member 6 and the movable dies 4, 4' or the solidified molten steel that has penetrated, or directly. Although a sliding force is exerted on the partition member 6, the partition member 6 is made of steel, for example, and even if it slides, it will not be easily damaged unlike a refractory material for a nozzle (for example, boron nitride).

使用することができる。 Further, the partition member 6 is always in contact with the movable molds 4, 4',
Since the contact length L can be made larger than the contact length L between the nozzle 3 and the partition member 6, even if the tip of the partition member 6 comes into contact with the molten steel, the molten steel will not flow through the gap.
It does not penetrate deeply into G 1 and therefore the partition member 6 is not heated to the extent that it loses its strength. Furthermore, the partition member 6 can be actively cooled by supplying cooling water from the cooling holes 8, so that the partition member 6 does not lose its strength. Therefore, metal or ceramics with excellent toughness can be used for the partition member 6.

れが少ない。 Furthermore, since the partition member 6 is fixed to the outside of the cavity 5 formed by the movable molds 4 and 4', and there is a gap G2 between the partition member 6 and the nozzle 3, the partition member 6 is separated from the movable mold 4. Even if a force is applied to the nozzle 3, the force is supported by the partition member 6, and unless the partition member 6 is deflected to a large extent, the force will not directly act on the nozzle 3, so there is little risk of the nozzle 3 breaking.

である。 In the embodiments of the present invention, the case where a block type is used as the mold has been explained, but a partition member is also used between the nozzle and the mold in the case of a twin belt type or a combination type of belt and wheel. It goes without saying that various changes may be made within the scope of the invention without departing from the gist of the invention.
