Abstract

PURPOSE:To arrange the process so as to be continuous, and to contrive the simpliification for plant configuration, the improvement of working efficiency, and the saving of man-hour, by arranging the hydraulic honing unit on the upstream side of the tandem cold rolling mill, and the differential rolling mill on further upstream side. CONSTITUTION:The uncoiled strip 2 is rolled by the differential rolling mill 11, and hereby, a friction force and a tension are inflicted upon the strip 2. As a result, the surface scale of the strip 2 causes cracks in it. Then, this strip 2, in a readily descaling condition, is sent to the hydraulic honing unit 12, in which the scale is removed from the strip surface in a short time. Hereafter, the strip 2 is sent to the cold rolling mill 7 for undergoing the cold rolling work. In which, since the strip 2 is previously rolled to some extent by the rolling mill 11, the draft percentage of the rolling mill 7 is reduced, or the number of included stand of the rolling mill 7 is reduced.
