Abstract

Walzstraße zum Walzen von stabförmigem Walzgut (11), z. B. Stabstahl oder Draht,

  • mit mehreren über Hydraulikzylindereinheiten (12) auf Watzspalte (s3 - s10) einstellbaren, von dem Walzgut (11) nacheinander durchlaufenen, zu Walzgerüstpaaren zusammengefaßten aktiven Walzgerüsten (3 - 10), mittels derer das Walzgut (11) unter Aufbringung von Walzkräften (F3 - F10) auf eine Endhöhe (h) und eine hierzu senkrechte Endbreite (b) walzbar ist,
  • wobei die Hydraulikzylindereinheiten (12) von Walzspaltregelungen (13) ansteuerbar sind, mittels derer walzkraftbedingte Auffederungen der aktiven Walzgerüste (3 - 10) zumindest zu Bruchteilen (t3 - t10) kompensierbar sind, und
  • wobei die Bruchteile (t3 - t10) für jedes aktive Walzgerüst (3 - 10) separat einstellbar sind.

Rolling mill for rolling rod-shaped rolling stock (11), e.g. B. steel bars or wire,
  • with a plurality of active roll stands (3 - 10), which can be adjusted in succession by the rolling stock (11) and are combined into roll stand pairs (3 - 10) and which can be used to set the rolling stock (11) while applying rolling forces (F3 - F10) can be rolled to a final height (h) and a vertical width (b) perpendicular thereto,
  • wherein the hydraulic cylinder units (12) can be controlled by roll gap controls (13), by means of which spring force-dependent suspensions of the active roll stands (3 - 10) can be compensated for at least to a fraction (t3 - t10), and
  • the fractions (t3 - t10) can be set separately for each active roll stand (3 - 10).
