Abstract
Provided is a manufacturing apparatus and manufacturing method of hot-rolled steel sheet which enables uniform cooling of a rolled material and improvement of the surface properties thereof. The manufacturing apparatus comprises: a rolling stand; a supplying device capable of supplying lubricant to work rolls and/or backup rolls; an online roll grinding device; and a removing device capable of removing at least part of the lubricant before the surface of the work rolls is ground by the grinding device. The manufacturing method comprises the steps of: removing at least part of the lubricant adhered to the work rolls, or to the work rolls and backup rolls using the lubricant removing device after completing rolling of a preceding material; grinding the work rolls using the online roll grinding device after the removing step; and supplying the lubricant to the work rolls and/or backup rolls from the lubricant supplying device.
