Abstract

PURPOSE:To shorten the length of the line, and to make cheap the installation cost and operating maintenance cost, by arranging in a rolling line the plural multipurpose rolling mills which can carry out both the rolling work and the correction work for the shape of the strip. CONSTITUTION:When one of the multipurpose rolling mills 29 is appointed to the rolling mill and another one to the leveler, the centers of upper and lower work rolls 9, 23, of one multipurpose rolling mill is placed just on the center line l of upper and lower backup rolls 3, 18; and then, the strip S is wound round upper and lower backup rolls 3, 18 and upper and lower work rolls 9, 23; the gap of work rolls 9, 23, is reduced and the rolling is carried out while the strip S is transferred in the arrow direction. In another rolling mill, the upper and lower forks are turned as far as alpha degrees counterclockwise, and the strip S is transferred in the arrow direction and is given the tension necessary for the correction of the shape between the upper and lower backup rolls 3, 18, and is given the necessary plastic bending force by the upper and lower work rolls 9, 23, for carrying out the correction of the shape.
