摘要： PURPOSE:To prevent overfill by detecting beforehand the magnitude and direction of the thrust force acting on work rolls, predicting the generation of overfill and adjusting right and left drafts and right and left rolling benders in accordance with the detected values after the trailing end of a material to be rolled passes through the previous rolling stand. CONSTITUTION:Tension is applied on a rolling material 1 and the direction and magnitude of the thrust force acting on work rolls 6 under rolling are detected with a thrust force detector 7 in rolling with a hot strip mill. The detected thrust force is added in an adder 10, and is inputted to an arithmetic device 11. On the other hand, when the trailing end of the material 1 passes through the previous rolling stand 2, the rolling load of a rolling load detector 8 is inputted to a detector 13, the detection signal whereof is inputted to an arithmetic device 11. At the same time, a control device 14 operates a screw down device 13 to adjust the right and left drafts and right and left roll benders of the stand 2.

摘要： PURPOSE:To permit the automatic inspection of apparatus by the constitution in which a signal for diagnosis is inputted to a hydraulic screw down system of a rolling mill and that the non-defectiveness and defectiveness of the apparatus and parts are diagnosed from the magnitude of the specific data on the waveform of the response signal of the system for the signal. CONSTITUTION:The operation of the rolling mill 1 is stopped and the hydraulic screw down system is disconnected from an automatic control device 7 for sheet thickness then an automatic diagnosing device 10 is operated in the stage of making automatic diagnosis. The device 10 transmits a diagnosis signal M from a function generator 11 to a servocontrol part 5 which drives a screw down cylinder 4. The displacement of a wedge 3 detected by a screw down position detector 6 is taken as a response signal N into an arithmetic unit 12. The unit 12 calculates the specific data on the waveform of the signal N. A comparator 13 discriminates the non-defectiveness and defectiveness of the apparatus condition of the hydraulic screw down system from the difference between the above-mentioned specific data and the set value and records the same in a printer 14. The comparator transmits an alarm command Y when the defectiveness is discriminated. The automatic inspection of the hydraulic screw down system is thus made possible.

摘要： PURPOSE:To promote the increase in production capacity by providing the differentiator calculating the difference in the rolling reduction set value and the present value of the rolling reduction quantity and by connecting the rolling reduction calculating device of different accuracy with switching to a differentiator. CONSTITUTION:A rolling reduction position detector 7 detects the present value of the gap (d) between rolling rolls 1, 3 and rolling reduction setter 10 outputs the set value (ds) of the set roll intervals to a memory device 8. A differentiator 11 calculates the difference between the present value of the roll intervals (d) detected by the detector 7 and the set value (ds) and inputs into the rolling reduction speed arithmetic device 13 or 14 of lower accuracy and higher accuracy via a changeover mechanism 12. The rolling reduction time is shortened with said mechanism with performing the control of rolling reduction with using the arithmetic device 13 of lower accuracy for the initial several passes. The positioning of higher accuracy is then performed with using the arithmetic device 14 of high accuracy for the several last passes. Consequently, the dimensional accuracy of a rolling material is secured and the production capacity is increased by the shortening in rolling reduction time.

摘要： PURPOSE:To make possible the initial setting of a draft position by providing means for calibrating the relation between the draft position and roll gap under ordinary rolling conditions. CONSTITUTION:The differential pressure signal 18 and screw-down cylinder position signal 19 outputted from a screw-down device 9 are stored one after another at every specified period at the same timing into a memory part 14. A comparator 13 compares the signal 18 and a reference differential pressure 20 at all times and when the signal 18 exceeds the pressure 20, the comparator 13 delivers a detection signal 21 to a control part 12 and an arithmetic part 15. The part 12 cuts off the full close command 17 to a screw-down device 10 and the device 9 maintains the screw-down cylinder position at the point of this time. The part 15 calculates and outputs the reference point of the screw-down position by the equation from the differential pressure data 22, screw-down position data 23, the thickness 22 of the rolling material before deformation and the change coefft. 25 of the change rate of the roll gap stored in the memory part 14.
