  • Patent number: 8676371
    Abstract: A rolling train for rolling a strip has a number of rolling stands and a coiler. The rolling stands have work and backing rolls. Data of the strip are fed to a control device of the rolling train which determines individual pass reductions for the rolling stands based on the data. It controls the main rolling stands and the coiler such that the strip is rolled in the main rolling stands according to the individual pass reductions and then coiled up. It determines the individual pass reductions such that they are zero and controls the rolling stand arranged directly upstream of the coiler such that—with respect to this main rolling stand—the tension in the strip on the outlet side is less than on the inlet side, but the strip runs through this rolling stand without undergoing any forming, at least on one side.

  • Publication number: 20100050727
    Abstract: A rolling mill, in particular, a cold strip tandem rolling mill, for producing a metal strip, with a number of stands is arranged in a tandem path, wherein, in a direction of production of the metal strip, a first stand is designed as driving stand and serves as inlet for a section of the tandem path, in which a primary thickness reduction of the metal strip occurs, and by corresponding control of the driving stand, an increase in the mechanical inlet tension of the metal strip can be achieved. In a method for controlling a rolling mill, in particular, a cold strip tandem rolling mill, for producing a metal strip, in a production direction of the metal strip, a first stand is controlled as driving stand, the driving stand achieving a significant increase in the mechanical inlet tension on the metal strip and a significant thickness reduction of the metal strip.
