  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To quicken the responsiveness of profile correction and realize an effective profile control, by varying the control period in case of requiring the output of manipulated variable which exceeds the possible manipulated variable within a given period of unit time of the profile operation terminal.
CONSTITUTION: The width direction stretch profiling pattern of the rolled material 1 is detected with the detector 5, is transmitted to the pattern recorgnition device 6, and is separated to parmaters related to asymmetrical and symmetrical components. The existing value of this parameter and the aimed value are compared and operated with the operation device 8, its deviation is transmitted to the operation devices 9, 10, the most suitable value of the roll bending force and the manipulated variable of the intermediate roll position is derived, and it is outputted to the control period decision device 11 as the calculation value of the setting variation amount. This is transmitted to the operation command device 12, after each manipulated variable has been varied to each operation terminal by a given control period, its setting value is calculated, and it is output as the aimed value to the intermediate roll position control device 15, the roll bending force control device 16, and the screw-down position control device 17.
