Abstract

PURPOSE: To reduce the fluctuation of breadth of sheet over all its length, by detecting the breadth of the blank material between the vertical roll and the horizontal roll, and by effecting the feedback control for the roll gap of the vertical roll so as to obtain the objective breadth on the run-out side of the horizontal roll correspondingly to rolling information including said detected breadth.
CONSTITUTION: The breadth meter 60 for detecting the intermediate breadth of the blank material 14 is installed between the edging roll 10 and the following horizontal roll 12 of the hot rolling mill. An arithmetic controller 64 for controlling the breadth receives the outputs of said breadth meter 60, the breadth meter 16 installed on the run-out side of the horizontal roll 12, and the process computer 62; then, the controller 64 sends the output signal to the roll gap positioner 20 of the edging roll 10. Hereby, the feedback control of the edging roll 10 depending on the outputs of the breadth meters becomes possible.
