LOCAL MODIFICATION OF THE ROLLER NIP IN THE REGION OF THE BELT EDGES OF A ROLLED BELT

摘要

The present invention relates to a method and a device for local modification of a roller nip in the region of the belt edges (10) of a rolled belt (1) in a roll stand (2). By means of the invention, the roller nip in the region of the belt edges (10) of the belt (1) can be locally modified during the hot rolling process. This problem is solved according to the invention by axially displacing the working rolls (3, 4) in opposite directions on a displacement path s, wherein s is greater than or smaller than (I) and Δr represents the frictional wear of the running surface (8) in the radial direction (R) and α represents the angle of inclination of the conical portion (7) of the particular working roll (3, 4).
