。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for controlling cooling of a steel plate by supplying cooling water to the surface of the steel plate while feeding the steel plate in its longitudinal direction.

であり、一般に、加工熱処理（Ｔ、Ｍ、Ｃ，Ｐ）技術と
呼ばれている。(Prior Art) Recently, in the thick plate manufacturing process, research on temper cooling processes has been active for the purpose of developing new steel types, reducing alloying elements, heat saving treatment, etc. The temper cooling process involves controlling the heating temperature and heating time of the material, and combines controlled rolling with forced cooling immediately after rolling. This series of controls, from heating and rolling to cooling, aims to control the transformed structure and improve the mechanical properties of thick steel plates, and is generally referred to as processing heat treatment (T, M, C, P) technology. ing.

イプ材の製造等における冶金的機構の解明とともに、オ
ンライン製造技術が確立されている。Among the above-mentioned processing and heat treatment technologies, heating and rolling control technologies have been developed over the past 10 years, mainly for cold regions, with the elucidation of the metallurgical mechanism in the production of high tensile kaline pipe materials, and online production technologies have been established.
（発明が解決しようとする問題点）
制御冷却技術は圧延直後の鋼板を７００〜８５０℃近傍
の高温域から１５０〜５５０℃程度まで強制冷却する。(Problems to be Solved by the Invention) Controlled cooling technology forcibly cools a steel plate immediately after rolling from a high temperature range of around 700 to 850°C to about 150 to 550°C.
制御冷却技術についてはまだ温度制御技術および形状制
御技術の而で不十分な状態にある。Regarding controlled cooling technology, temperature control technology and shape control technology are still insufficient.
特に、冷却終了温度は製品の機械的性質に大きな影響を
芋えるために、精度の高い温度制御が必要であるが、こ
れに応えるに十分な温度制御技術はまだ確立していない
。In particular, since the cooling end temperature has a large effect on the mechanical properties of the product, highly accurate temperature control is required, but temperature control technology sufficient to meet this requirement has not yet been established.
すなわち、圧延設備から送られて来た熱鋼板は、加熱炉
から冷却装置入側に至るまでの冷却履歴および鋼板内の
場所による冷却条件の相違により、鋼板は長手方向およ
び１咄方向について一様な温度分布をしていない。鋼板
の長手方向に関しては、先端から後端に向かうに従い温
度が下がる傾向にある。したがって、従来の冷却制御で
は、第４図に示す直線ａのように先端から後端に向かう
に従い直線的に下がる温度パターンを想定して、冷却装
置入側の鋼板温度を設定していた。In other words, the heated steel plate sent from the rolling equipment is uniform in the longitudinal direction and in the rolling direction due to the cooling history from the heating furnace to the entrance to the cooling equipment and the difference in cooling conditions depending on the location within the steel plate. There is no proper temperature distribution. In the longitudinal direction of the steel plate, the temperature tends to decrease from the front end to the rear end. Therefore, in conventional cooling control, the temperature of the steel plate on the entrance side of the cooling device is set assuming a temperature pattern that decreases linearly from the leading end to the trailing end, as shown by straight line a shown in FIG.
しかし、加熱炉から圧延機列を経て冷却装置入側に至る
までに鋼板は複雑な条件のもとで冷却されるので、実際

パターンを設定すると、冷却終了温度は目標値から大き
く外れ、高い精度で熱鋼板を冷却することはできない、
その結果、所要の機械的性質が得られず、また品質も鋼
板全長にわたって一様ではない。However, since the steel plate is cooled under complex conditions from the heating furnace through the rolling mill row to the cooling equipment entrance, the actual temperature fluctuates as shown by the curve in Figure 4, and The temperature pattern may deviate considerably from the set temperature pattern. Therefore, in this case, if the temperature pattern on the inlet side of the cooling device is set like the above straight line a, the cooling end temperature will deviate greatly from the target value, and the hot steel plate cannot be cooled with high accuracy.
As a result, the required mechanical properties cannot be obtained, and the quality is not uniform over the entire length of the steel plate.

温度となるように前記鋼板速度を調節する。(Means for Solving the Problems) The steel plate cooling control method of the present invention presets the steel plate cooling start temperature, cooling water volume density, cooling zone length, and steel plate speed based on the cooling conditions, and sets these in advance. While feeding the steel plate in the longitudinal direction according to the value, cooling water is supplied to the surface of the steel plate to cool the steel plate. Then, the temperature of the steel plate is detected on the inlet side of the cooling device, and the speed of the steel plate is adjusted based on the detected temperature on the inlet side so that the steel plate reaches the target cooling end temperature.

し、送り方向に配列した複数の冷却段のノズルから鋼板
の上下面に冷却水を供給して行う。The hot steel plate is transported and cooled, for example, as follows. That is, the steel plate is conveyed by roller tables before and after the cooling device, and by a plurality of pairs of upper and lower rollers arranged in the feeding direction within the cooling device and sandwiching the steel plate. The steel plate is cooled by supplying cooling water to the upper and lower surfaces of the steel plate from the nozzles of a plurality of cooling stages arranged between a pair of adjacent upper and lower rollers and arranged in the feeding direction.
この出願の第２の発明は、上記鋼板速度の調節に続いて
鋼板の先端が冷却ゾーンを通過すると冷却装置の出側で
鋼板温度を検出し、出側検出温度に基づ！！鋼板が冷却
終了目標温度となるように前記鋼板速度を調節する。The second invention of this application detects the steel plate temperature on the outlet side of the cooling device when the tip of the steel plate passes through the cooling zone following the adjustment of the steel plate speed, and based on the detected temperature on the outlet side! ! The speed of the steel plate is adjusted so that the steel plate reaches the target cooling end temperature.

場合には、鋼板速度を遅くなるように調節する。したが
って、鋼板は冷却ンーンでより長く冷却されることにな
り、冷却終了温度はより低くなって目標温度に近くなる
。冷却装置入側の温度が低い場合にはこの逆になる。(Function) When the steel plate temperature detected at the inlet side of the cooling device is higher than the set temperature, the steel plate speed is adjusted to be slower. Therefore, the steel plate is cooled for a longer time in the cooling cycle, and the cooling end temperature becomes lower and closer to the target temperature. The opposite is true when the temperature on the inlet side of the cooling device is low.
鋼板の先端が冷却ゾーンを通過し、冷却装置の出側で鋼
板温度を検出する場合、出側検出温度が１．１標冷却温

に近くなる。冷却袋と出側の温度が低い場合にはこの逆
になる。When the tip of the steel plate passes through the cooling zone and the temperature of the steel plate is detected on the exit side of the cooling device, when the detected temperature on the exit side is higher than the 1.1 standard cooling temperature, the steel plate speed is adjusted to be slow. As a result, the steel plate is cooled for a longer time in the cooling zone, and the cooling end temperature becomes lower and closer to the target temperature. The opposite is true when the temperature of the cooling bag and the outlet side is low.
