Abstract:
A method of rolling rod-shaped rolling stock, particularly rod steel or wire, in a roll stand having two work rolls, wherein the work rolls are adjustable relative to each other in an adjusting direction by a hydraulic cylinder unit, and wherein the work rolls together form a roll groove with an actual roll gap, and wherein the rolling stock exits the roll stand with an actual height and an actual width and at a rolling speed, the method comprisingrolling the rolling stock with an actual rolling force;measuring the actual rolling force;measuring with the aid of the actual rolling force a roll gap spring-back resulting from the rolling force;determining with the aid of the roll gap spring-back and a desired roll gap a roll adjustment correction value such that the actual roll gap approaches the desired roll gap; andchanging a roll adjustment within a stand control time by the roll adjustment correction value.
