    • PROBLEM TO BE SOLVED: To provide a system and a method for cooling a hot-rolled steel strip by which the steel strip is cooled at high cooling rate uniformly and stably when cooling water is supplied onto the upside of the hot-rolled steel strip. SOLUTION: This system is provided with upper header units 21 for supplying bar-shaped cooling water toward the upside of the steel strip 10. The upper header units 21 are composed of a first upper header group which comprises a plurality of first upper headers 21a arranged in the conveying direction and a second upper header group which comprises a plurality of second upper headers 21b arranged in the conveying direction and each of upper headers 21a, 21b of the first upper deader group and the second upper header group has piping composition provided with an ON-OFF mechanism 30 which makes the ON-OFF control (the control of the start and the stoppage of water injection) of the jetting (injection) of the bar-shaped cooling water possible respectively and independently.
