Abstract

PURPOSE:To make possible good shape control with a simple construction by providing hydraulic cylinders in the respective positions of the upper, middle and lower parts of the roll chocks supporting upper and lower work rolls, connecting these to the same hydraulic piping systems and mutually independently controlling the three hydraulic piping systems. CONSTITUTION:Upper and lower work rolls 1, 2 are supported by a pair of axially moving rolls. Hydraulic cylinders 31, 32, 33 are provided to the upper, middle and lower parts respectively of the roll chocks 12, 13 of the upper, lower work rolls 1, 2. On the driving side as well, hydraulic cylinders 34, 35, 36 are provided respectively to the upper, middle and lower parts of the roll chocks 14, 15. These hydraulic cylinders are connected to three systems of hydraulic pipings 37, 38, 39 connected to a hydraulic pump 45. Three systems of these hydraulic pipings are mutually independently controlled and the upper work roll 1 and lower work roll 2 are given six kinds of different bending states.
