PROBLEM TO BE SOLVED: To provide a cooling facility and a cooling method of a steel plate for cooling the steel plate properly on a hot rolling line by a compact structure when performing the controlled rolling of the steel plate. SOLUTION: The cooling facility of the steel plate feeds cooling water to upper and lower surfaces of the steel plate 10 while passing the steel plate 10 when the steel plate 10 is hot rolled, and has nozzles 22a, 22b for feeding cooling water obliquely toward the upper surface of the steel plate 10 from an upper part of the steel plate 10. The nozzles 22a, 22b are arranged such that ejections of cooling water on the steel plate 10 oppose each other in the carrying direction of the steel plate 10. COPYRIGHT: (C)2007,JPO&INPIT
