Abstract
In a method to replace a pair of rolls of a rolling mill stand during a downtime period, worn rolls fitted with chocks are extracted from the mill stand and positioned on means of displacement that bear a pair of new rolls without chocks. The method sets the means of displacement in motion so that the worn rolls are aligned with a chock extraction device. The chock extraction device is used to remove the chocks from the worn rolls. The means of displacement are actuated so that new rolls are now aligned with the chock extraction device. The chock extraction device is used to reinstall, on the new rolls, the chocks. After the new rolls have been fitted with the chocks, the new rolls are inserted in the mill stand so that the downtime period is reduced and the number of chocks in service is likewise reduced.
