Abstract

Mit Hilfe dieses Prozeßleitverfahrens sollen die aktuel­ len arbeitenden Kaliberdurchmesser (Di) einer kontinu­ ierlichen Walzstraße mit mehreren Walzgerüsten (1,2,3,i) und Walzen (4 bis 9) mit Einzelantrieben sowie der Kali­ berverschleiß (dDi) selbsttätig erfaßt werden. Die Kali­ berdurchmesser werden laufend als Quotient aus der ak­ tuellen Stabgeschwindigkeit (vi) des Walzgutes (26) und der aktuellen Walzendrehzahl (ni · üi) ermittelt. Bei eingefahrener Walzstraße werden Referenz-Kaliberdurch­ messer (D0i) für jede Walze (4 bis 9) und jedes Walzge­ rüst (1 bis 3,i) erfaßt und gespeichert. Durch Diffe­ renzbildung zwischen dem Referenz-Kaliberdurchmesser (D0i) und dem aktuell arbeitenden Kaliberdurchmesser (Di) kann der Kaliberverschleiß laufend ermittelt wer­ den. With the help of this process control procedure, the current working caliber diameter (Di) of a continuous rolling mill with several rolling stands (1,2,3, i) and rolls (4 to 9) with individual drives as well as the caliber wear (dDi) are to be recorded automatically. The caliber diameter is continuously determined as the quotient of the current bar speed (vi) of the rolling stock (26) and the current roll speed (ni · üi). When the rolling mill is retracted, the reference caliber diameter (D0i) for each roll (4 to 9) and each roll stand (1 to 3, i) is recorded and stored. By calculating the difference between the reference caliber diameter (D0i) and the currently working caliber diameter (Di), the caliber wear can be continuously determined.
