A method for the strip-edge-oriented shifting of the intermediate rolls (11, 11′) in a six-roll rolling mill comprising respectively a pair of workrolls (10, 10′), intermediate rolls (11, 11′) and backup rolls (12, 12′), whereby at least the intermediate rolls (11, 11′) and workrolls (10, 10′) have devices for axial shifting cooperating with them and each intermediate roll (11, 11′) has a barrel elongated by the amount of the CVC-shifting stroke and a one sided setback (x) in the region of the strip edge. The method is characterized in that the upper intermediate roll (11) is shifted in the direction of the drive side (AS) and the lower intermediate roll (11′) is shifted in the direction of the service side (BS)—or conversely—relative to the neutral shift position (Szw=0 mm) symmetrically to the rolling mill center (y-y) be respectively the same amount in the direction of their (x-x).
A method of strip-edge-oriented shifting of the intermediate rolls (11, 11′) in a six-roll rolling mill, comprising respectively a pair of workrolls (10, 10′), a pair of intermediate rolls (11, 11′) and a pair of backup rolls (12, 12′) whereby at least the intermediate rolls (11, 11′) and the workrolls (10, 10′) cooperate with devices for their axial shifting and each intermediate roll (11, 11′) has a barrel elongated by the amount of the CVC-shifting stroke wtih a one-sided setback (x) in the region of the strip edge (14),
A rolling mill for strip-edge-oriented shifting of the intermediate rolls, have elongated roll barrels on both sides, especially for carrying out the method according to the invention, characterized in that the intermediate rolls (11, 11′) each have an elongated barrel extended by the amount of the CVC stroke which is disposed symmetrically with respect to the neutral shifting position (Szw=0 mm) at the rolling mill center (y-y).
