摘要:
A method of influencing the strip contour in the edge region of a rolled strip in which by superimposing a conventional CVC contour the harmful side effect of a unilaterally narrowing roll on the body portion of the roll gap is compensated. Special CVC rolls are used as work rolls for influencing the strip contour in the edge areas. The special CVC roll for influencing the strip contour in the edge area is a roll with a profile, which, starting from a tapered end, has the steadily changing diameter differences of a continuously variable crown, which, in accordance with the invention, is profiled in axial direction in such a way that during its axial displacement the resulting undesirable component of the effect of the conical taper, i.e., the change of the elastic behavior of the roll set, is compensated, wherein this occurs especially to such an extent that additional conventional adjusting measures, such as redistribution of the rolling force or roll bending, are sufficient for maintaining the desired geometry of the roll gap over a wide range of a rolling schedule.
