摘要

The mill has a roll stand (1) comprising rollers (4, 5, 6) surrounding a rolling axis in a star-shape, where the rollers are arranged in a roll housing. The stand has a stand frame (3), and bearing housings (7, 8, 9) for accommodating the rollers are arranged in the stand frame. The bearing housings are arranged on guide bolts (10, 11) in the frame, where the guide bolts are arranged parallel to each other. One of the guide bolts is provided with an adjusting device for adjusting a correction roller angle in a plane that is perpendicular to a roller center line.
