Title:
COOLING DEVICE FOR STEEL SHEET, AND MANUFACTURING DEVICE AND MANUFACTURING METHOD FOR HOT-ROLLED STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2011/001898
Kind Code:
A1
Abstract:
In a hot-rolled steel sheet manufacturing line, provided is a cooling device for a steel sheet, which is excellent in discharging water without blocking the movement of a steel sheet or the sheet passage, and also provided are a manufacturing device and a manufacturing method for a hot-rolled steel sheet.
The cooling device (20) for a steel sheet is disposed on the downstream process side of the final stand (11g) of a hot finish rolling machine (10) and includes a plurality of cooling nozzles (21c, 22c) provided so as to be able to cool a steel sheet (1) conveyed on a conveyance roller (12). The cooling nozzles are provided on the upper and lower surface sides of a region through which a steel sheet passes and are enabled to eject cooling water toward the region through which the steel sheet passes. A lower surface guide (40) is provided on the lower surface side and has an inflow opening (42) through which cooling water ejected from the cooling nozzles located on the lower surface side passes and an outflow opening (43) through which cooling water dropped downward passes so as to be able to be discharged. The inflow and outflow openings are alternately disposed in the moving direction of the steel sheet.
