Abstract

PURPOSE:To always keep a work roll surface clean, and to manufacture a bright steel sheet with an excellent luster, in case of rolling a bright steel sheet with a dry type temper rolling apparatus, by arranging a nonmetallic brush rool very closely to the surface of a work roll in order to jet a compressed gas from the core of the brush roll. CONSTITUTION:A steel sheet P uncoiled from a payoff reel 11 is fed through a tension roll 12 to a dry type temper rolling apparatus constituted of upper and lower work rolls 1, 1 and backup rolls 2, 2, and is finished thereby into a bright steel sheet. A nonmetallic brush roll 3 made of nylon, etc., is installed on the feed-in side of each of work rolls 1, 1; a compressed gas is jetted out of the core of the brush roll 3 and cooperates with the brush in removing dusts from the surface of the work rolls 1 by a dry system; the removed dust is sucked and discharged by a fan 6 through a venting duct 5. Hereupon, it is practicable that a fine abrasive grain of 200-1,000 gauge number is applied to the surface of the brush roll 3. By the present method, the surface of the work rolls 1, 1 is always kept clean so that a bright steel sheet with an excellent luster is manufactured.
