Abstract
A cooling device and a cooling method for a hot strip allow uniform and stable cooling of the strip at a high cooling rate when supplying the coolant to the upper surface of the hot strip. The cooling device includes an upper header unitfor supplying a rod-like flow to the upper surface of the strip. The upper header unitis formed of the first upper header group including plural first upper headersarranged in a conveying direction and a second upper header group including plural second upper headersarranged in the conveying direction. The cooling device is provided with an ON-OFF mechanismto allow each of the upper headersandof the first and the second upper header groups to independently execute the ON-OFF control (start/end injection control) of an injection (feeding) of the rod-like flow.
