摘要： There are provided cooling equipment and a cooling method for a steel plate or sheet which can properly cool a steel plate or sheet with a compact size on a hot rolling line, for example, during controlled rolling of the steel plate or sheet.
Specifically, steel-plate or sheet cooling equipment supplies cooing water onto upper and lower surfaces of a steel plate or sheet 10 while the steel plate or sheet 10 is passing during hot rolling, and includes nozzles 22a and 22b that obliquely supply the cooling water onto the upper surface of the steel plate or sheet 10 from above. The nozzles 22a and 22b are arranged so that jets of cooling water oppose each other in the transferring direction of the steel plate or sheet 10 on the steel plate or sheet 10.
More specifically, pass-type cooling equipment 20 has a high water flow rate of 4 m 3 /m 2 min or more.摘要翻译： 本发明提供的冷却设备和用于钢板或片能够适当地冷却钢板或片材具有一个紧凑的尺寸上的热轧生产线中，例如，将钢板或片的控制轧制过程中的冷却方法。 具体地说，钢板或片材的冷却设备用品咕咕水到钢板或薄板10，同时将钢板或片材10在热轧期间被传递的上表面和下表面，并包括喷嘴22a和22b也倾斜地供给冷却水输送到 从上面的钢板或片材10的上表面上。 喷嘴22a和22b被布置为使得没有冷却水的射流反对在钢板上或片材10分的钢板或片材10的传递环方向彼此更具体地，匹配式冷却设备20具有高的水流速 为4米3 /米2分钟以上。

摘要： The invention provides cooling equipment of a steel plate or sheet, which has good equipment maintainability, has excellent draining property when supplying a large amount of cooling water to the under surface of the steel plate or sheet, and performs efficient cooling uniformly in a widthwise direction to achieve high cooling speed; and a method of manufacturing the steel plate or sheet having high quality. More specifically, the cooling equipment includes a plurality of protector plates 34 and nozzle trains. The protector plates 34 are disposed obliquely with respect to a direction of transferring of a steel plate or sheet 10 and at equal intervals. The nozzle trains are provided between the protector plates 34 and obliquely with respect to the direction of transferring, for supplying cooling water to the under surface of the steel plate or sheet 10. The nozzle trains have the same number of tube-shaped nozzles 32 disposed, respectively, on virtual lines 36 drawn at certain pitches in a plate or sheet width direction, and the top ends of the circular-tube-shaped nozzles 32 are positioned below the top ends of the protector plates 34.
