Abstract

PURPOSE:To widen the optionality of the sheet shape control, and to obtain products in a good quality, by making the length of the effective surface of a backup roll and the length of an annular groove of a crown roll, shorter than the length of the effective surface of a work roll, and by permitting upper and lower bending devices to work independently of each other. CONSTITUTION:The axial length l1 of an annular groove 51 of a variable crown roll 48 and the length l2 of the effective surface of a lower backup roll 7, are both made shorter than the length of the effective surface of upper and lower work rolls 1, 3. The size of a crown to be given to the variable crown roll 48 is adjusted by changing the pressure of working fluid in the annular groove 51, by switching a changeover valve 55 or by the pressure regulating action of a pressure regulating valve 54. The upper and lower increase bending devices 13, 14 and upper and lower decrease bending devices 15, 16 are driven by switching the changeover valves 23a, 23b so as to work independently of each other of upper and lower devices or to work simultaneously. By the present constitution, the cross sectional shape of a rolled metallic strip is controlled to a good condition.
