Document Type and Number:

WIPO Patent Application WO/2011/125670

Kind Code:

A1

Abstract:

Disclosed are a method for producing and a device for producing a hot-rolled steel sheet that are able to evenly cool a rolled member and to increase the surface quality of the rolled member. The device for producing a hot rolled steel sheet is provided with: a rolling stand; a supply means that can supply a lubricant to a work roll and/or a backup roll; an online roll grinding device; and a removal means that can remove at least a portion of the lubricant before grinding the surface of the work roll by means of said grinding device. The method for producing a hot rolled steel sheet has: a step wherein, when rolling a plurality of rolled members using said production device, at least a portion of the lubricant adhered to the work roll, or the work roll and the backup roll, is removed using the lubricant removal means after completion of rolling of the leading rolled member; a step wherein, after said step, the work roll is ground using the online roll grinding device; and a step wherein lubricant is supplied towards the work roll and/or the backup roll from the lubricant supply means.
