    摘要： A rolling control device (10) updates a preset load value Pset based on operation actual results at timings ta to tb. The rolling control device (10) derives a plasticity coefficient Qchk based on operation actual results at timings tb to tc. When the determining that it is necessary to re-update the updated preset load value Pset based on the plasticity coefficient Qchk, the rolling control device (10) updates the preset load value Pset again based on the operation actual results at the timings tb to tc.

    摘要： A roll mill for rolling a product has a roll stand with working rolls and a control device. The product has a head part and is moved towards the stand at a product head part speed. The working rolls form a rolling gap. The control device controls the stand such that, before the product head part enters the gap, the rolls are rotated at a peripheral speed which is essentially the same as the product head part speed; the gap is vertically adjusted to essentially a product head part thickness, on the feeding side, before the product enters the gap; and, during or following the insertion of the product into the gap, the gap is closed to a pre-determined value, and the peripheral speed of the working rolls is modified, especially increased, according to the gap, essentially at the same time as the closing of the gap.

    摘要： A cold-rolling train has a plurality of rolling stands and a strip feeding device to which an initial setpoint speed is sent to feed the cold strip to the first stand at an initial actual speed corresponding to the initial setpoint speed. A first setpoint speed is sent to the first stand so that associated rolls rotate. Between the first and next passed-through rolling stand is a thickness detection device detecting a first actual thickness. A base output signal is determined using the first actual and setpoint thicknesses and is used to adjust the first setpoint speed, but not the initial setpoint speed, conforming the first actual to the first setpoint thickness. Between the feeding device and the first rolling stand is an initial thickness detection device detecting an initial actual thickness. The initial setpoint speed is adjusted by a initial feed-forward controller to adjusted a setpoint product mass flow.

    摘要： A method of monitoring the physical state of a hot-rolled sheet or hot-rolled strip while controlling a plate rolling train for the reversing working a hot-rolled sheet or hot-rolled strip. For the reversing rolling of the hot-rolled sheet or hot-rolled strip a rolling stand is provided. At a starting point, an initial state of the hot-rolled sheet or hot-rolled strip in a model is determined, from which state at least one physical state variable is derived. Further, a cyclical updating of the state during the working of the hot-rolled sheet by using the model of the hot-rolled sheet or hot-rolled strip and the plate rolling train is provided, wherein monitoring of the path of the hot-rolled sheet or hot-rolled strip and operating parameters influencing and/or reproducing the state are taken into account.

    摘要： Drive loads for a plurality of drives of a mill train for rolling rolling stock with a plurality of rolling stands each being assigned at least one drive, are adjusted essentially to a first set point value on the basis of operation of the mill train in accordance with a first pass sequence. Redistribution of drive loads is improved, by adjusting the drive loads during the rolling to a second set point value different from the first setpoint value based on operating the mill train in accordance with a second pass sequence different from the first pass sequence, wherein at least during the adjustment of the second set point values a feed rate of the rolling stock into the mill train is adjusted as a function of a discharge rate of the rolling stock which is arranged upstream of the mill train in the direction of mass flow.
