Abstract
PURPOSE:To eliminate break scab, slag inclusion, fin, etc, which may cause edge defects, before completion of finish rolling, by pressing and contacting scrapers with specified pressure to the both side faces of intermediate rolled material while moving in the hot rolling line. CONSTITUTION:Along a guide path 11A of a side guide 11 disposed in a position before the final rolling pass in a hot rolling line, a scraper 17 connected to a crevice 15 is moved in and out at right angle to the hot rolling line direction by the action of an air cylinder 14. At this time, the front face of the scraper 17 is pressed and contacted to the both side end faces of an intermediate rolling material 1 being in motion at a contact pressure of 2 to 20kg/cm<2> within the range not deforming the rolling material. This contact pressure should be preferably set at about 5 to 10kg/cm<2> in the case of general rolling at a temperature of 950 to 1050 deg.C. The rake angle theta with respect to the intermediate rolling material 1 is set approximately at right angle.
