Document Type and Number:
WIPO Patent Application WO/2014/084373
Kind Code:
A1
Abstract:
[Problem] To provide a hot-rolled sheet passing guide capable of suppressing temperature fluctuations in the longitudinal direction of a hot-rolled steel sheet by efficiently discharging, from above the hot-rolled sheet passing guide, cooling water injected toward the lower surface of the hot-rolled steel sheet, and suppressing early-stage wear to thereby extend the life thereof.
[Solution] A hot-rolled sheet passing guide (30) is disposed between table rolls (21, 21) for conveying a hot-rolled steel sheet in a hot rolling line, and is characterized by being provided with a plurality of nozzle holes (31) provided at positions corresponding to cooling nozzles (27) disposed between the table rolls (21, 21), and water discharge holes (32) each formed between the nozzle holes (31) adjacent to each other in the sheet width direction of the hot-rolled steel sheet (5) to be conveyed and characterized in that the water discharge hole (32) is configured from an extension portion (34) extending in the sheet passing direction (F) of the hot-rolled steel sheet (5) to be conveyed, and wide hole portions (33) formed at both ends of the extension portion (34) in the sheet passing direction (F) and increased in a sheet width direction (F).
