構造となっている。(Prior art) There are various types of belt-type continuous casting machines that continuously manufacture steel plates such as sheet bars directly from molten steel.
Figure 1 shows some typical examples. The belt-type continuous casting machine shown in the figure is of a narrowing type, and while maintaining a gap for holding molten steel and solidified shell over a predetermined distance, a plurality of guide rolls 3a, 3b, 3c,
3a, 3b, and 3c, metal belts 1 and 2 are disposed opposite to each other and serve as long side surfaces, and the metal belts 1 and 2 are in close contact with the metal belts 1 and 2 near the side edges of these metal belts. The short side mold 4.5 constitutes a casting space. In particular, the short side mold 4.5 has an injection nozzle diameter of approximately 100 m.

設けである。On the back side of the metal belt 1.2 of the belt-type continuous casting machine, a cooling pad 8 provided with water supply holes and discharge holes, that is, a belt cooling device is provided. The water supply hole of this cooling pad is
As shown in FIG. 2a, one row is provided in the width direction of the cooling pad, the next row is provided with drainage holes, and the row of water supply holes and the row of drainage holes are alternately arranged in the longitudinal direction of the cooling pad 8, that is, in the casting direction. It is provided for.

That is, this water film plays the role of cooling the metal belt so that its temperature does not rise due to the heat received from the molten steel in the casting space, and also supports the load represented by the static pressure of the molten steel applied to the metal belt. It plays a role in preventing the metal belt from being worn out by keeping the cooling pads in a non-contact state.

け冷却パッドの幅方向に設けである。Conventionally, as a means for supplying cooling water between a metal belt and a cooling pad, a method of dividing the cooling pad in the width direction and controlling the flow rate of cooling water supplied to each compartmented chamber was disclosed in Japanese Patent Laid-Open No. 6.
It is described in Japanese Patent No. 0-158959. On the back side of this cooling pad, water supply headers 12 are provided corresponding to the rows of water supply holes of the cooling pad, as shown in Fig. 3a, and the number of water supply headers 12 is provided for cooling in a number corresponding to the number of sections of the cooling pad. It is provided in the width direction of the pad.

アウトを防止する試もある。In addition, as shown in Fig. 3b, the diameter of the water supply hole of the cooling pad becomes thicker toward the end of the cooling pad, that is, toward the short side mold (by reducing the pressure drop, the amount of cooling water is increased, There is also an attempt to prevent breakout by using hot water between the short side mold and the metal belt.

とも試みられている。Furthermore, as shown in FIG. 3c, by providing another water supply pipe 13' at the end of the cooling pad, the amount of cooling water from the end of the cooling pad facing the short side mold is increased, and the cooling water is increased between the short side mold and the short side mold. Attempts have also been made to prevent breakouts between metal belts.

るために短辺鋳型を移動させた場合に次のような問題が
生じる。(Problems to be Solved by the Invention) In all of the conventional techniques and attempts described above, cooling water is supplied to each row of water supply holes provided in the casting direction of the cooling pad. For this reason, when the short side mold is moved to change the width of the slab, the following problem occurs.
特開昭６０−１５８９５９号公報に記載されている方式
では、冷却パッドを細かく区画しなければならず、しか
も鋳片中と短辺厚を含むベルト幅以外への給水量が増加
し、水の使用量の面から不利である。In the method described in JP-A-60-158959, the cooling pad must be divided into small sections, and the amount of water supplied to areas other than the belt width, including the inside of the slab and the short side thickness, increases. This is disadvantageous in terms of usage amount.
また、冷却パッドの給水孔径を冷却パッド端部の方向に
順次大きくする試みでは、短辺鋳型を移動させた場合、
ある鋳造中以外では短辺鋳型に面した給水孔径が小さく
なり必要流量が確保されるのはある鋳造中のみであると
いう問題が生じる。In addition, in an attempt to gradually increase the water supply hole diameter of the cooling pad toward the end of the cooling pad, when the short side mold was moved,
A problem arises in that the diameter of the water supply hole facing the short side mold becomes small except during a certain casting process, and the required flow rate is secured only during a certain casting process.
また、冷却パッドの端部に別の給水管を設ける試みでは
、短辺鋳型の移動範囲内に多数の給水管を設けなければ
ならない。このために配管同士が干渉する可能性がある
ために、短辺鋳型を移動させて鋳片幅を変更するケース
にこの試みを適用することは困難である。Further, in an attempt to provide a separate water supply pipe at the end of the cooling pad, a large number of water supply pipes must be provided within the movement range of the short side mold. Because of this, there is a possibility that the pipes may interfere with each other, so it is difficult to apply this approach to cases where the width of the slab is changed by moving the short-side mold.

管の複雑さを解消することを目的とする。The present invention aims to prevent hot water pouring by increasing only the amount of water supplied directly under the short-side mold even when the slab width is changed, and to avoid unnecessary water supply to areas other than directly under the short-side mold as much as possible. The aim is to eliminate the complexity of

A feature of the present invention is that a header is provided in the vertical direction of the cooling device for the water supply hole in the area where the slab width can be changed, so that the water supply to the vertical header can be switched, and a cooling water flow rate control valve is provided. This is a cooling device for a belt-type continuous casting machine.
さらに、本発明を第４ａ〜第４ｃ図に基き詳細に説明す

にするとよい。As shown in FIG. 4a, the belt cooling device, that is, the cooling pad, has water supply holes 9 in the casting direction of the cooling pad as described above.
The rows of and the rows of discharge holes 10 are provided alternately, and the area involved in changing the slab width is within the range shown in the figure. The back side of this cooling pad is shown in FIG.
It is preferable to provide a common header for each water supply hole or a plurality of water supply holes.
第４ｃ図に各ヘッダー１２′への給水管の配管を示す。FIG. 4c shows the piping of the water supply pipes to each header 12'.

おく。The figure shows the piping of the water supply pipe on one side of the area involved in changing the slab width, but when piping the water supply pipe on both sides of the area involved in changing the slab width, it is necessary to install the water supply pipe at the end of the cooling pad. It is also possible to collect the water supply pipes to the headers in the vertical direction and rows at more equal positions and lead them to an electromagnetic switching box.In either case, a flow control valve 17 is provided in the water supply pipes. .

する。When changing the width of the slab, the width change detector 16 detects the amount of displacement from the standard position and transmits it to the electromagnetic switching box 15, and the cooling water is supplied only directly below the mold on the short side by the action of the electromagnetic valve. A small flow rate pump 14 that supplies cooling water is connected to a water supply pipe that supplies cooling water directly under the short side mold, and a flow rate control valve 17 is connected.
The amount of cooling water can be increased to a predetermined amount. on the other hand,
The water supply pipe to areas other than directly under the short side mold is a large flow pump 14.
', and the flow rate control valve 17 controls the amount of cooling water to a predetermined level.

By setting the flow rate of cooling water to areas other than directly under the mold at a predetermined flow rate, the pump load can be reduced. Furthermore, since the header is provided in the vertical direction of the cooling band, the complexity of piping can be eliminated.
