Abstract
An apparatus for controlled cooling of hot steel plate while constraining and conveying the plate by constraining rolls horizontally which is inexpensive and enabling continuous control of the cooling ability over a broad range, that is, a cooling apparatus for spraying hot steel plate hot rolled and transferred between pairs of constraining rolls with cooling water from pluralities of lines of spray nozzles so as to cool the same, which apparatus has lines of gentle cooling spray nozzles and lines of strong cooling spray nozzles with different orifice shapes and enables continuous control of the cooling ability over a broad range due to the fact that a maximum cooling water impact pressure integrated value of the lines of gentle cooling spray nozzles and a minimum cooling water impact pressure integrated value of the lines of strong cooling spray nozzles are continuous.
