    摘要： A facility is provided for manufacturing a steel plate excellent in steel plate shape and mechanical property while setting low cooling-water spraying performance in a descaling step and achieving uniform cooling in a cooling step. Specifically, a hot rolling mill 3, a first hot leveler 5, a descaler 4, and cooling equipment 6 are arranged in that order from the upstream side in a conveying direction. A pressure P [MPa] at the point of impact of cooling water sprayed from the descaler to each surface of a steel plate 1 is greater than or equal to 1.5 MPa.

    摘要： Provided is a technique which uniformly cools a hot rolled steel plate at a high cooling rate when cooling water is supplied to an upper surface of the hot rolled steel plate. To be more specific, in cooling equipment or a cooling method for a hot rolled steel plate which is arranged on a hot rolling line of a steel plate, the cooling equipment includes: a header which supplies cooling water to an upper surface of the hot rolled steel plate; cooling water jetting nozzles which are suspended from the header for jetting rod-like water flow; and a dividing wall which is arranged between the hot rolled steel plate and the header, wherein a large number of water-supply inlets which allow the insertion of lower end portions of the cooling water jetting nozzles thereinto, and a large number of drain outlets which drain the cooling water supplied to the upper surface of the hot rolled steel plate onto the dividing wall are formed in the dividing wall.
