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.
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 comprising
A method of rolling rod-shaped rolling stock, particularly rod steel or wire, in a front roll stand and in a rear roll stand, each roll stand having two work rolls, wherein the work rolls are adjustable relative to each other in an adjusting direction through a hydraulic cylinder unit, wherein the work rolls together form a roll groove with an actual roll gap, and wherein the rolling stock exits each roll stand with an actual height and an actual width at a rolling speed, and wherein the adjustment directions of the work rolls of the front roll stand and of the rear roll stand extend perpendicularly of each other, the method comprising carrying out in each roll stand the steps of
