Abstract (en)

[origin: WO0141947A1] The exit thickness (hm) of strip in a metal rolling mill is calculated by estimating input and exit strip velocities (V and v) and using a mass-flow balance equation. V and v are estimated by measuring angular velocities in the uncoiler reel (1) and coiler reel (2), estimating the initial radii of the uncoiler and coiler reels, and applying the measured and estimated values to a mathematical calculation to obtain estimated V and v.
