Abstract
PURPOSE: To increase the processing precision, by simultaneously and comprehensively controlling the plate thickness and plate breadth of the material being rolled, which are related with each other, in a tandem rolling mill.
CONSTITUTION: The plate thickness and plate breadth of the material being rolled 1 by rolling mills A to E having a plurality of stands are respectively detected by detectors 13, 10, and are inputted into a computer 20. The deviation between the detected value and set point is calculated and inputted, and a plate thickness control signal and a plate breadth correction signal to cancel the effect of the plate thickness control signal are calculated. As for the plate breadth control signal, similar calculations are made. And the sums of control and correction signals of plate thickness and plate breadth are supposed to be ΔS°, Δt°, which are outputted to a roll opening control device 21 and a tension control device 22. The device 21 calculates the deviation between the signal from position detector 16 and signal ΔS°, and operates a device 15E so that the deviation becomes zero. The device 22 calculates the deviation between the signal from tension detector 6 and signal Δt°, and operates a roll driving device 12D so that the deviation becoms zero.
