Abstract
PURPOSE: To decrease off-gauge in plate thickness of rolled material, and to increase rolling efficiency, by incorporating a plate-thickness-detecting unit, a tensile-force- detecting unit, and a tensile-force-compensation control unit in the control unit described in the title.
CONSTITUTION: When a material 1 to be rolled having passed through a rolling mill 2 is bitten by a rolling mill 3, the tensile force t3 of the roll 3 for passing plate becomes equal to the tensile force t2' of the roll 2 for releasing plate. At that time, a tensile force compensation control unit 21 is so operated that the tensile force detected by a tensile-force-detecting unit 25 becomes equal to a prescribed value tO, and controls a speed control unit 8 through a speed setting unit 18. Then a rolling reduction compensation unit 17 gives command signal to a rolling reduction control unit so as to open a screw down driving unit 11 by a quantity proportional to t2'. At the next step, the plate thickness S2' of the material to be rolled having left the roll mill 2 is detected by a plate thickness detecting unit 22, and the tensile force compensation control unit 21 is operated in roder to compensate the tensile force between the rolling mills 2, 3 according to the deviation signal, whereby the rotation speed of the roller driving motor 5 is adjusted.
