摘要： A hot rolling mill for a steel plate or sheet, which is superior in terms of equipment cost, equipment maintainability, and cooling performance and is capable of efficiently manufacturing a steel plate or sheet having good characteristics by appropriately controlling the temperature of a rolling material; and a method for hot rolling a steel plates or sheet are provided. Specifically, cooling equipment 20 for supplying cooling water onto a top surface and a bottom surface of a steel plate or sheet 10 that is being conveyed is provided at a position near an entrance side and an exit side of a hot rolling mill 12. The cooling equipment 20 includes an upper header 21 having upper nozzles 22 for jetting rod-like water flows 23 onto the top surface of the steel plate or sheet 10 at an angle of depression ¸ U in the range of 30° to 60°, which is positioned such that remaining cooling water 24 supplied to the steel plate or sheet is retained by work rolls 12a. The cooling equipment 20 further includes a lower header 31 having lower nozzles 32 for jetting rod-like water flows 33 onto the bottom surface of the steel plate or sheet 10 at an angle of elevation in the range of 45° to 90°, which is positioned between the work rolls 12a and a table roller adjacent thereto.

摘要： There is provided a method for manufacturing a hot-rolled steel sheet having a large thickness and a large width, in which a steel sheet having a larger sheet thickness, a larger sheet width and a lower temperature can stably be cut at a cutting load equal to that of a conventional steel sheet having a usual sheet thickness, a usual sheet width and a usual temperature. In a rough rolling step, a shape of a crop portion formed at a front end of the steel sheet in a conveying direction is adjusted into a fishtail shape by width rolling of a width rolling machine and horizontal rolling of a horizontal rough rolling machine, the steel sheet is formed so that the shortest length L (mm) from a concave portion bottom to a convex portion top of the fishtail shape satisfies Equation (1) mentioned below, and an intermediate portion between the concave portion bottom and the convex portion top, defined as a desired cutting location, is cut: 2 X + 30 ‰¤ L ‰¤ 300 in which X is a maximum deviation (mm) of the cutting location of a crop cutting machine and 0 ‰¤ X ‰¤ 90.
摘要翻译：本发明提供一种厚度大且宽度大的热轧钢板的制造方法，能够在切削载荷相等的情况下稳定地切断板厚大，板宽，温度低的钢板与具有通常片材厚度，常用片材宽度和常用温度的常规钢片相当。在粗轧工序中，通过宽度轧制机的宽度轧制和水平粗轧机的横向轧制，将在钢板的输送方向前端形成的裁切部的形状调整为鱼尾形，钢板形成为从鱼尾形状的凹部底部到凸部顶部的最短长度L（mm）满足下述式（1）以及凹部底部和凸部顶部之间的中间部，定义为期望的切割位置，被切割：2X + 30‰L≤300，其中X是作物切割机的切割位置的最大偏差（mm）和0‰X 90。
