Abstract

PURPOSE:To eliminate the edge drop of the product, and to roll the sheet material into excellent section shape, by giving flexibility to the large diameter work roll, and by giving the deflection with the roll bender. CONSTITUTION:Since the large diameter work roll 16 has a flexibility, the spring force or the hydraulic pressure of the roll bender 21 expands the gap A between the cluster roll chock 15 and the large diameter work roll chock 17, and the large diameter work roll 16 is deformed like as the curve l. Similarly, the roll bender 22 expands the gap B between the large diameter work roll chock 17 and the backup roll chock 19, and the large diameter work roll 16 is deformed like as the curve m. As a result, the sum of deflections depending on respective roll bender 21 and 22 becomes the final deflection of the large diameter work roll 16. The large diameter work roll 16 together with the work roll 12 are previously given the necessary deflection corresponding to the quality of rolled material, thickness and breadth of the sheet, the section shape of the sheet, etc.
