WATER DEFLECTING DEVICE AND WATER DEFLECTING METHOD FOR STEEL PLATE COOLING WATER IN HOT ROLLING STEP

Title:

WATER DEFLECTING DEVICE AND WATER DEFLECTING METHOD FOR STEEL PLATE COOLING WATER IN HOT ROLLING STEP

Document Type and Number:

WIPO Patent Application WO/2016/006402

Kind Code:

A1

Abstract:

In the present invention, a plurality of water deflecting nozzles of a water deflecting device comprise one or more solitary distal water deflecting nozzles or distal water deflecting nozzle groups. The solitary distant water deflecting nozzles form distal-end unit water deflecting regions that do not comprise one end of the width direction of a steel sheet conveyance surface but do comprise the other end. The distal water deflecting nozzle groups are formed such that the distal-end unit water deflecting regions and one or more internal unit water deflecting regions that do not include the two ends of the width direction of the steel sheet conveyance surface are arranged in order from one end side to the other end side while overlapping with one another in the width direction of the steel sheet conveyance surface, and arranged in order from an upstream side to a downstream side without overlapping in a direction of conveyance.
