Abstract

Ein Verfahren zur Querschnittsregelung von Walzgut über eine Walzgut-Schlingenregelung, insbesondere zwischen Walzgerüsten (WGn-1, WGn) in Profilwalzstraßen (1), sieht vor, daß über die Schlingenhöhe (h) die Horizontalkräfte im Walzgut verändert und darüber Breitungen des Walzgutes gezielt beeinflußt werden.

Figure 00000001
A method for cross-sectional control of rolling stock via a rolling stock loop control, in particular between rolling stands (WG n-1 , WG n ) in profile rolling mills (1), provides that the horizontal forces in the rolling stock are changed via the loop height (h) and, in addition, widening of the rolling stock be influenced in a targeted manner.
