摘要： PURPOSE:To enhance the accuracy of a predictive value and to improve the quality and yield of a product by installing crown detectors at the inlet and outlet sides of a final stand and installing further a shape detector at the outlet side. CONSTITUTION:Sheet crown detectors 4 for detecting the sheet crown of a rolling material are installed at the inlet and outlet sides of a final stand No.6, and a shape detector 5 doe detecting the flatness of material is installed at the outlet side of said stand No.6. And the output values CH, Ch of two detectors 4 and an output value (lambdal) of detector 5, and further an actual value of the stand No.6 and a shape-variation factor computed previously based on rolling conditions, are fetched in a computer 6. Computation is performed by the computer 6 based on the fetched data to identify a predictive equation. The error of the equation is minimized and the shapes, etc. between stands are prevented from deterioration, by using a correction factor of each influence factor for the setup.

摘要： PURPOSE:To correct the asymmetry of a material to be rolled, and to perform a stable rolling, by removing the variation of rolling load due to the load of bending force from rolling loads at the operating and driving sides, and correting the asymmetry basing on the true difference of the rolling loads. CONSTITUTION:A calculator 25 calculates a moment M, and a calculator 26 calculates the load difference DELTAPM due to the moment basing on the calculated results. On the other hand, the loads PW, PD at the operating and driving sides are detected by load cells 8, 9 provided to a lower back-up roll, and a calculator 12 calculates the difference DELTAP between them. A calculator 27 calculates the load difference DELTAPR, caused truely by the asymmetry of rolling, basing on the difference between DELTAP and DELTAPM. The differences DELTAS of rolling reduction for correcting the asymmetry is obtained by using the true load difference DELTAPR with the aid of a computer 13, and then the asymmetry of a material to be rolled is corrected without being influenced by the movements of intermediate rolls by controlling rolling reduction motors 15, 16 connected to rolling reduction screws 10, 11 through a rolling-reduction commanding device 14.

摘要： PURPOSE:To control at the same time the shape and the sheet crown of a rolled sheet to the aimed sizes, by interposing an axially shiftable intermediate roll between a work roll and a backup roll of a tandem rolling mill, and by exactly controlling the position of the intermediate roll. CONSTITUTION:In case of rolling a material 7 to be rolled with work rolls 1, 2, axially shiftable intermediate rolls 3, 4 are interposed between backup rolls 5, 6 and work rolls 1, 2. The intermediate rolls 3, 4 are equipped with shifters 11, 12 and the work rolls 1, 2 are provided with roll benders 8, 9. At rolling a material 7 to be rolled, aimed final shape and sheet crown are preset in a setter; the setter compares the aimed values with signals sent from a shape detector and a sheet crown detector installed on the run-out side of the final rolling stand, and outputs deviation signals for shape and sheet crown, which are then inputted to a bending force command device 10 and an intermediate roll's position command device 13; these command devices 10, 13 then exactly control the bending force to be loaded on the work roll and the position of the intermeidate roll with respective adjusters 11, 12.

摘要： PURPOSE:The titled controlling apparatus possible to always keep constant the sheet crown on the run-out side, by actually measuring the feed-in side sheet crown for the purpose of operating and forecasting the sheet crown on the run-out side, and also, by correcting above operation depending on the specified other data. CONSTITUTION:The feed-in side sheet crown is measured by two sheet gauge meters 18, 19, and their difference is operated and detected by the operator 20. The feed-in side sheet crown at the point when the steady state is settled is taken as the reference value, and the variation of the measured sheet crown from this reference value is taken as DELTACH. Besides, the sheet gauge B sent from the setting board 14 and the sheet gauge H sent from the sheet gauge meter 19 located in the middle position are inputted to the computer 21 which then operates above stated DELTACH and the sheet crown's variation DELTACh on the run-out side. Next, the computer 22 connected to this computer 21 operates the necessary data depending on this forecast DELTACh and the present bending force Q, the distance delta, the rolling load P, the sheet breadth B, etc., and sents the result required in preventing the variation of DELTACh to the command unit 24.

摘要： PURPOSE:To make the force of inertia to instantaneously evolve, to improve the bitability, and to reduce the space, by making faster the circumferential speed of the work roll driven by the auxiliary motor that the circumferential speed of the work roll driven by the main motor, at bitting the material into the work rolls provided with the main motor and the auxiliary motor. CONSTITUTION:The power of the main motor 8 is transmitted to the work roll 1 through the reduction gear 7 and the spindle 4. On the other hand, the power of the auxiliary motor 11 is transmitted to the work roll 2 through the flywheel 10, the reduction gear 9 and the spindle 5. Now, before the rolled material 3 is bitten into the work rolls 1, 2, the work roll 2 is rotated at faster circumferential speed than the circumferential speed for the rolling work. Next, when the rolled material 3 is bitten into work rolls 1, 2, the entire force of inertia of the work roll 2 at this moment is given to the rolled material 3 which is hereby smoothly bitten into work rolls 1, 2. Then, the work roll 2 is rotated at slower circumferential speed than that before bitting.

摘要： PURPOSE:To improve the response speed of gauge fluctuation detection and realize accurate gauge control, by controlling the peripheral speeds of both rolls so that the rolling load may coincide with the set rolling load, when rolling at different peripheral peeds of upper and lower work rolls. CONSTITUTION:A plate material 3 from a let-off machine 4 is rolled by a rolling mill 6, and wound on a coiler 8. An upper work roll 1 is driven by a motor 10, and the peripheral speed of the motor 10 is detected by a speed detector 11, and is controlled to the upper work roll set peripheral speed V0i by means of a speed adjusting device 12. On the other hand a lower work roll 2 is driven by a motor 13, which is controlled to the lower work roll set peripheral speed V1i by means of speed detector 14 and speed adjusting device 15. The set gauge in a gauge setting device 16 is converted into a set rolling load P0 by a load setting device 17, and the deviation between this load and rolling load P detected by a load cell 18 is calculated in a substractor 19. An operator 20 proportionally integrates the deviation signal. According to this result, the set peripheral speeds of both rolls V0i, V1i are operated.
