  • Publication number: 20090235707
    Abstract: Disclosed is a rolling mill comprising a roll stand with working rolls, a roll train located at the feeding end of the roll stand, and a control device. The working rolls form a roll gap. The control device triggers the roll stand such that the working rolls rotate at a certain peripheral speed while triggering the roll train located at the feeding end of the roll stand in such a way that the leading edge of the strip-shaped rolling stock reaches the roll gap at a feeding speed that is greater than the peripheral speed. The control device adjusts the peripheral speed and the feeding speed to each other in such a way that a potential angled position of the leading edge relative to the roll gap is at least reduced as a result of said adjustment.

  • Patent number: 6697699
    Abstract: Method for influencing relevant quality parameters of a rolling strip, particularly the profile or flatness of the rolling strip, in a roll stand with rolls, by adjusting the crownings of the rolls, i.e., the surface geometry of the rolls in the longitudinal direction of the rolls, wherein the crowning of the rolls is adjusted by an adjustable cooling of the rolls or of their surfaces in longitudinal direction of the rolls. The cooling of the rolls is adjusted by a controller (1) as a function of the actual value (pactual) of the crowning and a predetermined setpoint value (psetpoint) of the crowning.
