Abstract

Bei einem Verfahren zum Richten von Metallbändern mittels einer Rollenrichtmaschine, bei dem das kontinuierlich längsbewegte Metallband zwischen einer Anzahl von in Bandlaufrichtung hintereinander angeordneten Richtwalzen (14,13) hindurchgeführt wird, die voneinander getrennt auf einem oberen und unteren Walzenstuhl (12,11) gelagert sind, werden zur Erzielung eines guten Richtergebnisses bei Metallbändern mit variablen Banddickenverlauf die Richtwalzen (14) an mindestens einem Walzenstuhl (12) so gesteuert, daß ihr Abstand zu den ihnen zugeordneten Richtwalzen (13) am anderen Walzenstuhl (11) sich abhängig vom Banddickenverlauf des Metallbandes (10) ändert. Die Richtmaschine weist hierzu an ihrem Bandeinlauf und -auslauf angeordnete Keilpaare (27) auf, die mit ihrer Keilschräge (27a) nach vorgegebenen Steuerprogrammen parallel zu den Achsen der Richtwalzen (14) verschoben werden.

Figure 00000001
In a method for straightening metal strips by means of a roller straightening machine, in which the continuously longitudinally moved metal strip is passed between a number of straightening rollers (14, 13) arranged one behind the other in the direction of strip travel, which are mounted separately on an upper and lower roller frame (12, 11) To achieve a good straightening result for metal strips with variable strip thickness, the straightening rollers (14) on at least one roller mill (12) are controlled in such a way that their distance from the associated roller (13) on the other roller frame (11) depends on the strip thickness curve of the metal strip (10) changes. For this purpose, the straightening machine has wedge pairs (27) arranged at its strip inlet and outlet, which are shifted with their wedge bevel (27a) parallel to the axes of the straightening rollers (14) according to predetermined control programs.
