Abstract (en)
[origin: WO2009106422A1] A strip (6) is fed to one of (2 - 5) the rolling stands (1 - 5) (rolling stand in question) of a multi-stand rolling mill with a known inlet thickness (d1 - d4) and exits the rolling stand in question (2 - 5) with a strip thickness (d2 - d5). Measurement parameters (vR, vW) are determined that are characteristic of the inlet-side velocity (v1 - v4) of the strip (6) and the outlet side velocity (v2 - v5) of the strip (6) with respect to the rolling stand in question (2 - 5). By means of the measurement parameters (vR, vW), the inlet-side velocity (v1 - v4) of the strip (6) and the outlet side velocity (v2 - v5) of the strip (6) are determined with respect to the rolling stand in question (2 - 5). By means of the inlet thickness (d1 - d4), the inlet-side velocity (v1 - v4) of the strip (6) and the outlet side velocity (v2 - v5) of the strip (6), the strip thickness (d2 - d5) is determined with respect to the rolling stand in question (2 - 5). Taking into account the determined strip thickness (d2 - d5), further measures are taken. The measurement parameter (vW) for the inlet-side velocity (v1 - v4) of the strip (6) is the roller peripheral velocity (vW) of the rolling stand (1 - 4) directly prior to the rolling stand in question (2 - 5). Alternatively or in addition, the measurement parameter (vW) for the outlet-side velocity (v2 - v5) of the strip (6) is the roller peripheral velocity (vW) rolling stand in question (2 - 5). The peripheral precession of the strip (6) in the respective rolling stand (2 - 5) is modeled. The respective velocity (v1 - v5) of the strip (6) is determined using the respective roller peripheral velocity (vR) and the peripheral precession of the strip (6) in the respective rolling stand (1 - 5).
