Abstract
PURPOSE:To lower the temp. of rolls largely at the cooling of rolls for hot rolling by cooling water, by specifying the injecting press. of the cooling water and its mean flow density. CONSTITUTION:The 1st drain board 8 and the 2nd one 9 are provided to a roll, and the roll is cooled by spraying a cooling water 7 from headers 6 at the rolling of a rolling material 12 by rolls for hot rolling. At this time, the injection press of the cooling water 7 is made <=10kg/cm<2>G which is sprayed on the roll surface, and the mean flow density of the cooling water to be supplied on the water sprayed roll surface is made 2-5m<3>/min.m<2>. Further, the cooling start- point of the roll viewed from the roll-biting exit is made <=50 deg. or preferably 14-30 deg. rotated angle. By this way, the saving of cooling water and the reduction of electric power cost are performed largely.
