幅方向に均一に冷却するという点で問題がある。 FIG. 1 shows a schematic layout of equipment generally referred to as continuous hot rolling equipment. In the area called cooling zone b on the hot run table a of this equipment,
The upper surface of the strip generally uses a laminar flow cooling method, which has a good cooling effect, while the lower surface of the strip is cooled by spraying cooling water from a number of spray nozzles. In addition, c is a finish rolling mill, d is a coiler, and S is a strip. However, with the spray method that cools the bottom surface of the strip, there is a lot of splashing of the cooling water on the strip surface, the nozzle is easily clogged due to foreign matter in the cooling water, and there are problems with uniform cooling in the width direction of the strip. .

A circular tubular header with an opening in the direction is provided below the strip passing surface of the table roller in parallel with the table roller, a water supply device is provided to supply cooling water to the header, and a plate-shaped water stream of cooling water is supplied from the slits to the header. The header is configured such that the header is blown up to the strip, and furthermore, a width adjusting body is provided so as to be rotatable concentrically with the header, and has a concave portion that gradually blocks the blown-up water flow from the width end toward the center in the width direction. It is characterized by this.

リツプＳ下面へ吹上げられるようになつている。 In FIGS. 2 and 3, 1 is a header provided below the strip S, and has a slit 2 formed linearly in the width direction of the strip S on its upper surface. The strip S is installed below the roller 3 in the width direction so that it is located approximately in the middle between the rollers (rollers of the hot run table) 3, 3. Inside this header 1, a water supply pipe 5 having a large number of water outlet holes 4 and supplying cooling water into the header 1 is inserted and installed concentrically, and as shown in FIG. 2, the cooling water is blown up toward the lower surface of the strip S in a plate-like (curtain-like) water flow 6.

There is. The width adjustment body 7 is
As shown in Fig. 3, the front (or rear) part has a planar shape in which the left and right sides are formed in a stepped (or slanted or arcuate) shape 8 so that the front part (or the rear part) becomes concave toward the center in the width direction. The cylinder rod 9 is driven to rotate around the water supply pipe 5, and the width of the plate-shaped water stream 6 is adjusted by the stepped portion 8 that is displaced thereby.

い。 With the above configuration, when cooling water is continuously supplied into the header 1 through the water supply pipe 5, the header 1
Cooling water is blown up from the slit 2 in the form of a plate-shaped water stream 6, and the plate-shaped water stream 6 passes between the rollers 3 and 3 and is injected onto the surface of the strip S without rebounding. That is, as shown in FIG. 4, the upper end of the plate-shaped water stream 6 hits the surface of the strip S and at the same time spreads out slidingly on the surface. Therefore, the strip can be cooled uniformly in the width direction. The width adjusting body 7 cuts the width end portion of the plate-shaped water stream 6 depending on its rotational position, and can freely adjust the width of the plate-shaped water stream 6 that actually contributes to cooling according to changes in the strip width, etc. Further, since the width adjustment body 7 performs the width adjustment at the time when the water stream is rectified by the header 1 and discharged as a complete plate-shaped water stream, the width adjustment does not impede the generation function of the plate-shaped water stream in any way.

The width can be adjusted freely without disturbing the rectification state, and the structure is simple and occupies less space, so it can be installed in narrow places such as between roller tables, and maintenance is easy. Demonstrates excellent effects.
