A large number of nozzle holes 4 are bored along the circumferential direction on the circumferential surface of the cylindrical body 2,
These nozzle holes 4 constitute an annular nozzle hole group 5 arranged in an annular manner, and a cylindrical nozzle box 6 is watertightly arranged in the cylinder body 2 so as to cover this nozzle hole group 5. The nozzle box is disposed along the circumferential direction of the circumferential surface of the cylindrical body in the area covered by the nozzle box. A nozzle body 3 is formed by the two surfaces of the cylinder having the nozzle hole 4 configured in this manner and the nozzle box 6, and a plurality of nozzle bodies 3 are provided at appropriate intervals in the length direction of the cylinder 2.

By controlling the temperature, this temperature difference can be brought close to zero. Incidentally, in performing such control, the flow rate regulating valve 7 is controlled by also referring to the temperature detected by the temperature detector 12 disposed near the inlet of the nozzle pipe 1.
Specifically, when the temperature difference between the target value and the temperature measured by the temperature detector 12 near the outlet side of the nozzle pipe 1 becomes large, the flow rate regulating valve 7 connected to each of the plurality of nozzle bodies 3 is opened to a large opening degree. However, when the temperature difference becomes small, the plurality of flow rate regulating valves 7 are opened with a small opening degree, or an appropriate number of the plurality of flow rate regulating valves 7 are closed and the remaining flow rate regulating valves 7 are opened with a small opening degree. This is to bring the temperature of the rolled material C closer to the target value. Note that the motor 14 that drives the pump 9
By adding rotational speed control, even more delicate and accurate temperature adjustment is possible.

仕上面を良くすることができる。 The present invention is constructed as described above, and one cylindrical nozzle pipe 1 whose front opening in the conveyance direction is widened in a truss shape is disposed on the conveyance path B between the rolling mills A of a hot rolling line. This nozzle pipe 1 is constructed by arranging a plurality of nozzle bodies 3 at appropriate intervals in the length direction of a cylindrical body 2, and each nozzle body 3 covers a nozzle hole 4 and the cylindrical body 2 in a watertight manner. It consists of a nozzle box 6 arranged as shown in FIG.
A large number of nozzle holes 4 are formed along the circumferential direction on the circumferential surface of the cylindrical body 2 in a portion covered by each nozzle box 6, and each of the nozzle bodies 3 is provided with a flow rate adjustment valve 7 for adjusting the flow rate of the coolant. , this flow rate regulating valve 7 is connected to a cooling body tank 8.
On the other hand, a temperature detector 12 for measuring the temperature of the material to be rolled C is provided in the conveying path B near the outlet and inlet of the nozzle pipe 1, and the flow rate regulating valve 7 is Since the respective opening degrees are adjusted, the rolling temperature of the rolled material C after it is extracted from the heating furnace and passed through the rough rolling mill is controlled by the cooling body,
For example, the temperature can be adjusted by cooling with water, steam, or the like. Therefore, by adjusting the rolling temperature through this cooling, it is possible to improve the mechanical properties and the finished surface of products such as steel bars.

なものとなるものである。 In particular, in this cooling atmosphere, since a plurality of nozzle bodies 3 are arranged in one nozzle pipe 1 at appropriate intervals in the length direction of the cylinder body 2, each nozzle body 3 can be controlled separately. By sending cooling water separately as appropriate from the nozzle holes 4 formed in a large number in the part of the nozzle body 3 covered by the nozzle box 6, cooling can be performed in a finely tuned manner depending on the thickness of the material to be rolled C. Since the space between the two nozzle bodies 3 is also within the single cylindrical body 2, it is filled with water vapor, and the change in the cooling temperature is not affected by the atmosphere at all. This is ideal for adjusting the rolling temperature of hot rolled materials.
