摘要： PURPOSE:To eliminate the need for a complicated preset control, etc., and to improve the reliability of a rolling mill by providing a ramp generator and switching means on each rolling stand while a plate passing speed ratio set by a speed ratio setter is fixed. CONSTITUTION:When the plate passing speed is changed from a usual condition, first of all, a speed changing command signal S, and its switching timing T1 are inputted into a switching contact point 10 and a flip-flop circuit 12. Then the switching contact point 10 becomes on condition and the flip-flop 12 is set to make the switching contact point 11 on condition. Therefore, the signal to be inputted into the ramp generator 9 is exchanged from the speed reference signal S0 to the speed changing command signal S1 and the speed reference signal S3 from the switching contact point 11 is also switched from the speed reference signal S0 to the speed switching signal S2. Further, by the speed changing signal S2 from the ramp generator 9, the speed value of the speed reference signal S3 is changed to the speed value of the speed changing command signal S1 from the speed value of speed reference signal S0 and the plate passing speed is changed to an arbitrary speed.

摘要： PURPOSE:To make the change in rate of acceleration and deceleration easy, by changing an apparent time and variably adjusting the rate of acceleration and deceleration, through the change in a reference time integrated with a time counter. CONSTITUTION:A reference clock C from a reference clock generator 5 of an acceleration and deceleration adjusting device is inputted to a time counter 6, where a reference time is summed every time the clock C is inputted, and the elapsed time after the start of acceleration and deceleration is measured. The count value is applied to a driving device 3 via an acceleration and deceleration controller 4 and the rotating speed of a rolling mill roll 2 to a work 1 to be rolled is controlled at the device 3. In inputting an acceleration and deceleration rate change request signal (e) from the device 3 to a reference time set circuit 7, every time the clock C is inputted to the circuit 7, the rate of acceleration and deceleration designated at the signal (e) is summed or subtracted to sum a reference time t0 to the counter 6. The value of the reference time integrated at the counter 6 is changed to make the change in the rate of acceleration and deceleration easy.

摘要： PURPOSE:To make possible the control of sheet breadth with high accuracy and fast response, by operating the corrective amount for the interstand tension required for absorbing the error of breadth on the exit side of the continuous rolling stand of the rolling mill, and by adjusting the rotational speed of the roll for controlling above stated interstand tension to the aim value. CONSTITUTION:The roll gap of the edger in front of the stand 1a is operated from the aim sheet breadth and other rolling conditions, and is preset by the setters 4, 5. The tension operator 9 operates the tension T between the reducing rolls 1a, 1b, from the rolling load F detected by the load cell 7, the rotational speed N of the motor 8, and the driving current I. On the other hand, the breadth deviation operator 6 operates the difference DELTAW between the detected breadth W and the reference breadth W*; then, the reference tension operator 10 operates the corrective amount DELTAT for the tension, from these values and above stated tension T, according to the formula. This DELTAT is inputted to the rotational speed operator 11, which then operates the corrective amount DELTAN for the rotational speed. The rotational speed control unit 12 controls the motor 8 so as to make the corrective amount to be DELTAN.

摘要： PURPOSE:To control the variation amount of the tension of a strip, and a difference in positions (heights) between two carriages to minimums, and to add the bending loss correction of the strip to its tension standard. CONSTITUTION:The variation amount of tension is controlled to the minimum by controlling the current of the looper motor 9 of a carriage 5 on a master side, and by controlling the looper motor 10 of a carriage 6 on a slave side by a speed with a quick response with a speed controller 40. Also, at the time of the failure of a tension meter 14, the device is changed over to a current control by a current, speed control changeover signal 37. Also, by correcting a tension standard signal 27 with functions (w. h ) of a strip width w and a strip thickness h by using a function generator 44 to make the tension standard signal 27 the tension standard signal 45 of the carriage on the slave side, a height between both carriages 5 and 6, is controlled to the minimum by correcting the bending loss of a strip 1.

摘要： PURPOSE:To provide a motor controller for suppressing a slip by controlling the rotational speed of the motor, that is, the rotational speed of a roll when slip is generated between a strip and the roll. CONSTITUTION:When slip is generated between a strip 1 and a roll 2, a rotational speed signal NFBK increases, resulting in NFBK>NC. In this case, when the comparison difference N(=NFBK-NC) exceeds a certain value, a deadband 14 sends an output, a current reference compensation signal can be obtained through multiplycation of a certain gain G in the limiter and a new current reference signal IREF can be obtained by subtracting a current reference compensation signal, in the subtraction unit 17, from the current reference signal outputted from an arithmetic unit 12. As a result, the current to be applied to the motor 3 is reduced (becomes lower than a total mechanical loss), resulting in drop of the rotational speed. Since the rotational speed of the roll 2 is reduced, the slip can be controlled.

摘要： PURPOSE:To bring the front end of a billet always to a prescribed position by determining an optimum position to start swiveling by the inlet side speed of the 1st rolling mill and the time since the start of swiveling till the end thereof. CONSTITUTION:The distance Lx from a detector 7 up to the position of the front end of the billet under transfer is calculated by a control device 16 from a detection signal 14 for the front end of the billet and a signal 15 for the transfer distance of the billet. The distance Ly from the detector 7 up to the front end position of the billet where the swiveling starts is also calculated by the device 16. A billet twister 8 is swiveled by a swiveling start command 18 outputted from the device 16 so that the swiveling of the billet 1 already clamped to the billet twister 8 by a clamping start command 17 is completed in the position B when the result of the calculations attains Lx=Ly.

摘要： PURPOSE:To conform the residual length of a rolling material coiled on an unwinding reel after completion of deceleration nearly with the target length by providing a deceleration ratio adjusting device to adjust the deceleration ratio of a speed controller. CONSTITUTION:The difference L between a sending length L and the residual length LR is calculated based on a carrier speed V and a circumferential length CA continuously after an arithmetic unit outputs a deceleration command 17 and whether the deceleration is executed normally or not is monitored to check the reasonableness. When the relational equation 1 exists, the deceleration is regarded as normal, the deceleration is continued as it is and when it does not exist, the deceleration is regarded as abnormal and the deceleration adjusting device 20 adjusts the deceleration ratio of the speed controller 6. Consequently, the speed controller 6 decelerates rolling rolls 3 with the optimum deceleration ratio and the residual length LR of the rolling material 1 coiled on the unwinding reel 2 after completion of deceleration conforms nearly with the target length.

摘要： PURPOSE:To remove a large ripple component of an analog input signal while obtaining an output signal without time delay, by outputting the proper combination of a preceding value and a current value. CONSTITUTION:A subtraction is operated with a subtractor 4 between the current value 2 of an output signal obtained from a sensor 1 and the preceding value 31 obtained from a holding circuit 3. The difference signal 5 thereof is compared with a reference value 71 from a reference source 7 by a comparator 6. Here, when the difference signal 5 is larger than the reference value 71, a changeover signal 61 is sent out and a signal 31 of the preceding value as output of the holding circuit 3 is sent to the next stage as output signal 8 with a changeover unit 10. When the difference signal 5 is smaller than the reference value 71, the signal 2 of the current value is sent to the next stage as output signal 8 with the changeover unit 10. As a result, when a ripple exists in the output of the sensor, the preceding value is held while when no ripple exists, the instantaneous value thereof is obtained.
