Strip-edge-based displacement of intermediate rolls in six-high rolling stand

摘要

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 (S_zw=0 mm) symmetrically to the rolling mill center (y—y) be respectively the same amount in the direction of their (x—x).
