    摘要： There are provided a cooling device and a cooling method for a hot-rolled strip in which the strip can be uniformly cooled from a leading edge to a trailing edge with coolant by properly realizing a great cooling ability and a stable cooling zone. Specifically, the following three methods are adopted. (1) Round nozzles 14 for ejecting inclined rodlike flows of coolant to a downstream side in the traveling direction of a strip 12 and round nozzles 14 for ejecting inclined rodlike flows of coolant to an upstream side in the traveling direction are arranged on an upper side of the strip 12 so as to oppose each other. (2) Round nozzles 14 for ejecting inclined rodlike flows of coolant from the upstream side of a roller table 9 toward just above the roller table 9 and round nozzles 14 for ejecting inclined rodlike flows of coolant from the downstream side of the roller table 9 toward just above the roller table 9 are arranged on the upper side of the strip 12 so as to each other. (3) Lower cooling nozzles 19 for ejecting coolant from between roller tables toward a lower surface of a strip 12 are provided on the lower side of the strip 12, and cooling nozzles 14 for ejecting inclined rodlike flows of coolant from the upstream side of a position where the coolant ejected from the lower cooling nozzles 19 collides with the strip 12 toward just above the position and cooling nozzles 14 for ejecting inclined rodlike flows from the downstream side of the position toward just above the position are arranged on the upper side of the strip 12 so as to oppose each other.

    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.

    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.
