摘要： PURPOSE:To improve the flatness of a sheet by comparing the influence coefft. patterns to the respective sheet flatnesses of work roll benders and intermediate roll benders with the influence coefft. patterns of intermediate roll shafts and operating the intermediate roll shifts. CONSTITUTION:A manipulated variable detector 13 compares the manipulated variables at respective manipulation ends with the limit values of the manipulated variables for the respective manipulation ends to asertain whether said variable exceed the limits or not. Then, the detector outputs the limot over signal to a flatness control circuit 16. An influence coefft. computing device 14 computes the model calculated values of the influence coefft. from the rolling data while the actual values of the manipulated variables are under measurement. The calculated values are outputted to an influence coefft. pattern comparing and computing device 15 and a flatness controller 16. The computing device 15 delivers the control decision signal to any of the work rolls 2A, 2B and the intermediate rolls 3A, 3B to the flatness control circuit 16 in accordance with the model calculated values of the influence coefft. calculated by the computing device 14. The control circuit 16 determines the manipulated variables of the intermediate roll shifts and outputs the same toward an intermediate roll shift controller 10.

摘要： PURPOSE:To make slack quantity of catenary constant and to enable stable automatic operation by arranging means for controlling tension of the catenary part with weight of the catenary part. CONSTITUTION:The steel strip 1 forms the catenary in steel strip treating part 2. Bridle rolls 4 at outlet side are driven with a bridle driving device 4A at outlet side controlled with the velocity and the bridle rolls 3 at inlet side are driven with a bridle driving device 3A at inlet side controlled with the current. Pulse generator 5 tracks the connecting part of a strip to obtain the position thereof from the bridle roll 3 at the inlet side. The position is calculated with a tracking arithmetic unit 6A. Data of the tracking arithmetic unit 6A is inputted to a strip wt. arithmetic unit 6B to calculate the weight of the strip in the catenary part. Based on this strip weight, the tension value is calculated with a tension reference arithmetic unit 7. This tension is varied together with shifting of the connecting part and the catenary quantity is held constant.

摘要： PURPOSE:To absorb the excess tension generated at winding a strip on a winding machine and to constrain the variation in tension by providing a vertically moving roll by a hydraulic cylinder at the upstream side of a winding machine. CONSTITUTION:When a tension is generated on a steel strip at the moment of the steel strip being wound in a winding machine 2, a tension is exerted on the dancer roll 3 pushed up by the specific pressure. In such case, when the tension more than the specified value is exerted, the dancer roll 3 is pushed down and excess tension is absorbed by the roll 3 to constrain the excess tension variation before and behind a skin pass mill 1. Namely, the tension reference signal given to a current control device 21 is inputted to a tension/pressure convertor 10 and converted into a pressure reference signal. The pressure signal outputted from a pressure control valve 11 is inputted to a pressure controller 13 together with the pressure detection signal detected by a pressure transducer 12 and this pressure reference signal control the pressure control valve 11 based on these signals. The dancer roll 3 is thus moved vertically and absorbs the tension variation generated between the skin pass mill 1 and winding machine 2.

摘要： PURPOSE:To roll a single coil into various kinds of thicknesses and to improve the productivity and yield of the products of many kinds of thicknesses and small volumes, by rolling a coiled stock from its one end to its other end while decreasing its thickness by a required length in sequence. CONSTITUTION:The whole length of a coiled stock 6 is first rolled into the largest thickness of the thicknesses to be rolled by a reversing cold-rolling equipment. Next, the remaining part of coil 6 is rolled into the 2nd thickness while leaving the required length of said rolled coil 6 at its one end. Thus, the coil 6 is rolled into a coil of the 2nd thickness successively to the thickest coil left previously by the required length at its one end. The rolled products A, B, C having the thicknesses respectively, decreased in sequence from one end to the other end of coil, are produced by a required length, by repeating said rollings thereafter.

摘要： PURPOSE:To pass the tail end of a band steel automatically from a reel to a rolling mill by calculating remaining coil diameter of rewinding side reel and changing driving of above-mentioned reel from current control to voltage control basing on signal of the result of calculation. CONSTITUTION:A current controlling device and a voltage controlling device are provided in driving controlling devices of left and right reels. The remaining diameter of rewinding side reel is calculated by an arithmetic unit and when the coil diameter corresponding to the length of band steel necessary for deceleration is attained, the driving of the reels is changed from current control to voltage control by a remaining diameter signal. Thus, the reel sends out the coil at equal speed with the rolling mill. When the tail end of the band steel passes a tail end detector provided between the rolling mill and rewinding reel, the rewinding side reel also changes current control to voltage control. In this way, the tail end of the band steel can be passed from the reeel to the rolling mill smoothly without stopping operation at each pass.
摘要翻译：目的：通过计算卷绕侧卷轴的剩余线圈直径，将带钢的尾端自动从卷轴传递到轧机，并根据计算结果的信号将上述卷轴从电流控制改变为电压控制。构成：在左右卷盘的驱动控制装置中设置电流控制装置和电压控制装置。倒带侧卷轴的剩余直径通过算术单元计算，并且当达到与减速所需的带钢长度相对应的线圈直径时，通过剩余直径信号将卷轴的驱动从电流控制改变为电压控制。因此，卷轴以与轧机相等的速度发出线圈。当带钢的尾端通过设置在轧机和卷绕卷轴之间的尾端检测器时，卷绕侧卷轴也将电流控制改变为电压控制。以这种方式，带钢的尾端可以平稳地从滚筒传送到轧机，而不会在每次通过时停止操作。

CONSTITUTION:When rollers 2A, 2B execute a change of a moving extent in the axial direction, a gate 10 is closed for a while and a storage device 11 stores it as a rolling load P* before a start of said change based on load detectors 8A, 8B, also inputs it to an arithmetic unit 13, and a plate width B of a rolling material 1, which has been set in advance by a setting device 12 is also inputted to the unit 13.

Thereafter, in the same way, a deformation quantity Sm2 is calculated, a difference S of both of them is outputted to a rollers 2A, 2B opening control device 14, and the device 14 drives rolling reduction driving devices 15A, 15B in accordance with the signal S, and corrects and controls the opening between the work rollers 2A, 2B.

摘要： PURPOSE:To restrain the change of a strip tension of a rolling mill to the minimum and to improve the quality of product by compensating a reference signal of mill speed in constituting a titled method, in a system where an installation at the inlet side of looper located at the front of the mill is controlled basing on the mill speed. CONSTITUTION:Speed detectors SS1, SS2 are attached respectively to motors 5M, 6M of a bridle roll 5 placed at the inlet of a mill 6 and the mill 6, and signals outputted from these detectors are inputted to a speed compensating circuit 11 to obtain the difference between both signals. Then a speed compensating signal corresponding to the change of a rolling reduction of the mill 6 is obtained to compare it with a speed reference signal outputted from a central speed reference circuit 8 by a comparator COM thereby the amount of difference obtained after said comparison is inputted to an inlet-side speed-reference circuit 9. An output of the circuit 9 is inputted to a speed controlling device 3VC to control the drive of a bridle roll 3 placed at the inlet of looper. Thus the speed of a strip at the inlet side of the mill 6 is made perfectly equal to that of the strip at the inlet side of the looper, and the position change of the looper 4 is eliminated thereby the purpose is achieved.
