摘要:
The invention relates to a roll stand comprising a pair of work rolls 1, 2 for rolling a metal strip B, comprising back-up rolls 8, 9, 10, 11 which provide lateral support to their respectively allocated work rolls 1, 2, with support force directed towards the work rolls 1, 2 being able to be applied to said back-up rolls by means of a force generation device, and comprising support rolls or intermediate rolls 3, 4 which are borne by a chock which can be slid into the roll stand W1, W2 in the direction of the longitudinal axis of said chock 7, and wherein said chock can be withdrawn from said roll stand, with each support roll or intermediate roll supporting an associated work roll 1, 2 in a direction which is essentially perpendicular to the direction of movement of the metal strip B. In such a roll stand, changing of the rolls can be carried out more quickly and easily in that the back-up rolls 8, 9, 10, 11 can be positioned from an idle position in which they are arranged outside the region where the chock 7 of the support roll or intermediate roll 3, 4 moves during slide-in or withdrawal, to an operating position in which they rest against the work roll 1, 2.

A device for measuring stress distribution across the width of flexible litudinally moving strip material, such as strip steel during coldrolling. The device includes a deflection measuring roller comprised of a plurality of rotatable sections mounted side-by-side. Some of the sections have force pick-ups fitted therein and the elements cooperatively function to detect and measure deflection as an indication of stress distribution across the strip.

摘要:
In a method for cold-rolling sheets and strips, measured values which characterize the surface evenness, especially the tensile stress distribution, are formed on the delivery side of a rolling mill and, in dependence thereon, adjusting members of the rolling mill are actuated which form part of at least one regulating circuit for the surface evenness of the rolled sheets and strips. Incorrect adjustments and disruptions in the rolling process on the basis of the different time responses of the individual adjusting members are avoided by adjusting the adjusting members at speeds so matched to one another that during at least a portion of the adjusting time, the ratio of the adjustments of the participating adjusting members remains constant, and all adjusting members reach their desired values simultaneously.
