PURPOSE:To prevent rolls from deflections, and to obtain a product excellent in band-shape and in band-crown, by supplying a lubricant to the surface of a surface plate arranged at the downside of a pass line, and rolling a steel band by using work rolls and back-up rolls. CONSTITUTION:In rolling a steel band, a surface plate 1 formed with grooves, etc. is fixed to the underside of a rolling pass line, and work rolls 2 and back- up rolls 3 are arranged at the upper side of the pass line, and rolling is performed while supplying a lubricant to the surface of the plate 1. Further, rolling oil is sprayed on the rolls 2 and 3 and on the upper surface of the steel band by an ordinary means. Then the plate 1 is prevented from the generation of deflection by said rolling method, and the deflection control is exercised relatively simply because of the small deflections of the rolls 2 and 3. A set of multiple roll mill is provided to the inlet side of the pass line as required. Thus a product excellent in band shape is inexpensively obtained by this method. |
