Abstract

PURPOSE:To control the shape of the rolled material, by operating the asymmetric component of the shape of the rolled material, the difference between the bending forces, and the difference between the screw positions, and by adjusting these values by the command unit. CONSTITUTION:The strip 1 is rolled by the work rolls 2, 3, and its shape on the run-out side is detected by the shape detector 6. The operator 7 extracts the asymmetrical component D depending on the signal produced from the detector 6. The computer 8 operates the optimum screw position and bending force. The computer 10 operates DS, DF, depending on information like as the rolling load (p), the sheet breadth (b), the draft percentage (r), etc., sent from the setting console 9. In respect of the symmetrical component, CS, CF, are inputted to the computer 11. The computer 11 operates the correcting values DELTAS, DELTAF. These correcting values are divided by the operators 12, 13, into + or -DELTAS/2, + or -DELTAF/2, which are respectively inputted to each of the command units for the screw position and the bending force, 14, 15, 16, 17. These command units add these inputs to the optimum screw position S and the bending force F produced from the computer 8, and produce the results to the left and right screw down devices 18, 19, and the left and right benders 20, 21.
