Abstract
PURPOSE: To improve the product quality in multirow continuous rolling by separating the upstream side stands by each rolling roll, and controlling the loop quantities, the number of revolutions of rolls and roll gaps of each rolling row.
CONSTITUTION: The upstream side stands are substituted with independent rolling mills by each rolling row. Detectors 6, 6' for loop quantities, tension and cross sectional areas are provided to the entrance side and exit side of each stand and the detection signals thereof are inputted to a control unit 10. In the control unit 10, the optimum control signals for roll revolution correction quantities, roll gap correction quantities, etc. are calculated. Upon receiving said signals 11, a control unit 12 emits the commands for the number of revolutions of rolls or roll gap adjustment of screw-down rolls 5. Thereby, the loop or tension of the material to be rolled of each row may be controlled by the simple means and the inter-row unbalances are reduced.
