Title:
COOLING METHOD AND COOLING DEVICE FOR HOT-ROLLED STEEL STRIP
Document Type and Number:
WIPO Patent Application WO/2014/103164
Kind Code:
A1
Abstract:
Provided are a cooling method and a cooling device for adjusting the volume of cooling water in two levels for each set of width direction headers when cooling a hot-rolled steel strip and for changing the steel strip cooling velocity in multiple levels using a simple method, the method and device being particularly effective for cooling the lower surface of a steel strip in a narrow space. Spray nozzles (5) are disposed in a row at a specified pitch in the width direction of the steel strip. In order that cooling water can be supplied from different piping systems for spray nozzles (5) that are adjacent in the width direction, the cooling headers (6) are configured so that: two systems are disposed per one set; a jetting valve (7) is installed on each; and individual cooling water jetting/stopping is possible.
