Abstract

Die vorliegende Erfindung betrifft ein Walzverfahren für stabförmiges Walzgut (5) insbesondere Stabstahl oder Draht (5), in einem Walzgerüst (1) mit zwei über eine Hydraulikzylindereinheit (12) relativ zueinander in einer Anstellrichtung (x) anstellbaren Arbeitswalzen (8), die zusammen ein Walzkaliber mit einem Ist-Walzspalt (s1) bilden, so daß das Walzgut (5) aus dem Walzgerüst (1) mit einer Ist-Höhe (h0) und einer Ist-Breite (b0) mit einer Walzgeschwindigkeit (v0) ausläuft, wobei das Walzgut (5) mit einer Ist-Walzkraft (F1) gewalzt wird. Erfindungsgemäß ist vorgesehen, daß

  • die Ist-Walzkraft (F1) erfaßt wird,
  • anhand der Ist-Walzkraft (F1) eine walzkraftbedingte Walzspaltauffederung (δs1) bestimmt wird,
  • anhand der walzkraftbedingten Walzspaltauffederung (δs1) und einem Soll-Walzspalt (s1*) ein Walzenanstellungs-Korrekturwert (δa1) derart bestimmt wird, daß der Ist-Walzspalt (s1) dem Soll-Walzspalt (s1*) angenähert wird, und
  • eine Walzenanstellung (a1) innerhalb einer Gerüstregelzeit (T) um den Walzenanstellungs-Korrekturwert (δa1) geändert wird.

The invention relates to a rolling process for rod - shaped rolled material (5), in particular steel bars or wire (5), in a rolling stand (1) with two work rolls (8) which can be adjusted relative to one another in an adjustment direction (x) by means of a hydraulic cylinder unit (12) form a rolling caliber with an actual roll gap (s 1 ) so that the rolling stock (5) from the roll stand (1) with an actual height (h 0 ) and an actual width (b 0 ) with a rolling speed (v 0 ) runs out, the rolling stock (5) being rolled with an actual rolling force (F 1) . According to the invention it is provided that
  • the actual rolling force (F 1) is recorded,
  • based on the actual rolling force (F 1 ), a roll gap suspension (δs 1 ) caused by the rolling force is determined,
  • based on the rolling force caused Walzspaltauffederung (.DELTA.S 1) and a desired roll gap (s 1 *) is determined, a roll adjustment correction value (.DELTA.a 1) such that the actual roll gap (s 1) is the desired nip approximated (s 1 *) , and
  • a roll pitch (a 1 ) is changed within a stand control time (T) by the roll pitch correction value (δa 1 ).
