Abstract: A method of rolling rod-shaped rolling stock, particularly rod steel or wire, in a roll stand having two work rolls which are adjustable relative to each other in an adjusting direction and which together form a roll groove with an actual roll gap, so that the rolling stock exits the roll stand with an actual height and an actual width at a rolling speed, wherein the rolling stock is rolled with an actual rolling force. The method includes the steps of adjusting the work rolls through a hydraulic cylinder unit; 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; and changing a roll adjustment within a stand control time by the roll adjustment correction value.
