    摘要： An apparatus for controlling a strip tension during flexible rolling of metal strip comprises a roll arrangement with at least one dancer roll, the position of said dancer roll being adjustable for controlling the strip tension of the metal strip,

    at least one hydraulic drive coupled to the dancer roll for adjusting the dancer roll, a hydraulic tank for hydraulic fluid, which is fluidly connected to the hydraulic drive via a hydraulic supply line, a controllable valve arrangement between the hydraulic tank and the hydraulic drive for controlling the hydraulic drive, a hydraulic pump with which the hydraulic drive is supplied with hydraulic fluid from the hydraulic tank, and at least one hydraulic pressure accumulator for temporarily storing hydraulic fluid previously delivered by the hydraulic pump, the hydraulic pressure accumulator being arranged between the hydraulic pump and the valve arrangement,
    wherein a pressure sensor is arranged in the hydraulic drive for determining the hydraulic pressure.

    摘要： Mill control system and method for metal strip rolling controlled in response to a sequence of controller scans are provided. A sensor suite is coupled to sense a plurality of parameters regarding the strip rolling. A model responsive to the sensed parameters is configured to estimate per scan at least one matrix based on the sensed parameters and indicative of state conditions of the strip rolling. A controller includes an inner control loop configured to effect a control law to generate a control vector per scan. The inner control loop may be configured to have dynamic characteristics, which remain substantially the same for each scan of the controller. The dynamic characteristics of the inner control loop are effective to determine a pointwise online control solution based on the matrix indicative of the state conditions of the strip rolling, without having to compute a Riccati control solution per scan.

    摘要： A time and work tracker that automatically collects and analyzes information about time and work performed on a wireless device is described herein. According to the present invention, a time and work tracking function is initiated on a wireless device. Thereafter, a user begins to perform work on the wireless device. As the user works, the tracking function on the wireless device collects data relating to the activities performed by the user. The collected data is then analyzed to determine what types of work the user has actually performed.

    摘要： Continuous rolling is conducted by interposing loopers respectively between a plurality of successive stands and connecting a rear end of a preceding bar to a top end of a next bar. Roll gaps of the respective stands are each controlled by thickness control units. Interstand mass flow variations are each controlled by mass flow control units. Looper heights are controlled by looper height control units. Further, interstand tensions are controlled by looper tension control units. If no looper is provided, the interstand tensions are controlled by looperless control units. A flying thickness change control unit tracks a connecting point. The flying thickness change control unit switches over looper tension control and looperless control and changes a reference tension and a reference looper angle so that tensile and flexural forces are not applied to this connecting point.

    摘要： This disclosure relates to a process for the regulation of the thickness of a flat product such as a strip, sheet or plate, being rolled in a hot tandem rolling mill, and the corresponding regulation device for carrying out the process. Regarding each stand of the rolling mill on which the adjustment is being performed, a constant rolling pressure is maintained, the gap is measured, the deviation between the measured gap and a set value corresponding to a desired thickness of the product is determined, and the necessary correction of the value of the tensile force applied on the product between the stand under consideration and the upstream stand in order to bring the gap back to its set value is determined. Finally, this correction of the tensile force between the stand under consideration and the upstream stand is performed.

    摘要： Apparatus for automatic control of the fill dimension of a product formed in a rolling mill by sensing the fill dimension of the finished product and comparing this value to a predetermined reference value to form a resultant error signal. This resultant error signal modifies the height of loops between successive stands of the mill to vary the product fill dimension. The apparatus includes provision for increasing the gain if successive errors of fill dimension in the same direction are sensed and for decreasing the gain if successive errors in the opposite directions are sensed.
