Abstract

PURPOSE: To increase plate crown control amount and improve quality by cooperatively performing pressure controlling of the double chock work roll bending devices provided to plural stands while maintaining a fixed ratio in the same direction.
CONSTITUTION: Pressure oil is supplied via line 8 to the double chock work roll bending devices 7 provided to stands. A controller (operator) 13 which operates pressure so as to permit plate crown controlling in shape blind zone from control information 14 is provided and the pressure ratio of every stand is set in each pressure setter 12 based on the command from the controller 13. Based on this set ratio, pressure regulators 9 are operated from the pressure setters 12. Based on the command from the controller 13, a solenoid valve 11 is operated to operate the roll bending devices 7 of the plural stands in the same direction while maintaining their pressures at a fixed ratio.
