Abstract (en)
[origin: EP1240955A1] To compute the roller gap contour between at least two rollers (A), at a rolling stand of the rolling mill, the roller gap contour is given on-line from the results of a combination derived from a prior computation and an on-line computation. The prior computation includes a distortion vector field e.g. the radial distortion field of a roller under a given loading. The result is shown as a Fourier series, and the prior work uses a finite element computation
