Abstract

PURPOSE:To freely control a shape of material to be rolled, by supporting work rolls and intermediate rolls of a multi cluster mill by chocks separated respectively, and adding a roll bending function to functions of roll shifting and back up roll crown adjusting. CONSTITUTION:In a multi cluster mill having a back up roll crown adjusting device, a roll shifting device, and a roll bending device; a back up roll crown quantity, roll shifting quantity, and roll bending force, optimum for a target shape of a material to be rolled, are calculated from informations about the quality of the material to be rolled, the width and thickness of sheet, etc. and informations about a rolling load, work roll crown, and others concerning the mill, to set said optimum values to a back up roll crown adjusting device, a roll shifting device, and a roll bending device. While rolling, a shape of material to be rolled is corrected by a shape deviation signal obtained from the difference between a shape detected signal and a set value of target sheet shape.
