Stabilization of the rolled product during opening and/or closing of a roll stand

A method, comprising:

• providing a plurality of rolling mill stands (1) in a rolling train, each having two working rolls (10) forming an associated roll gap (S) in which a rolled product (B) transported in a conveying direction (R) can be formed, wherein a positioning of at least one working roll (10) per rolling mill stand (1) is variable in a plane perpendicular to the conveying direction (R), and the method further comprises:
• conveying the rolled product (B) through the associated roll gap (S) of each of the rolling mill stands (1) in the conveying direction (R) and at the same time opening or closing one or more of the rolling mill stands (1) by correspondingly increasing or decreasing the associated roll gap (S);
• during opening or closing of a corresponding rolling mill stand (1), detecting a position of the rolled product (B) in front of and/or behind the associated roll gap (S) transverse to the conveying direction (R);
• and
• changing the positioning of the corresponding working roll (10) depending on the detected position, so that the rolled product (B) is stabilised at a target position during opening or closing of the corresponding rolling mill stand (1),
• wherein closing the corresponding rolling mill stand (1) includes transitioning the two working rolls (10) from a pulled-up state in which a thickness of the rolled product (B) is not reduced to a lowered-down state in which the thickness of the rolled product (B) is reduced, and
• wherein opening the rolling mill stand (1) includes transitioning the two working rolls (10) from the lowered-down state to the pulled-up state.

A rolling mill stand (1) for rolling a rolled product (B), comprising:

• two working rolls (10), which form a roll gap (S), in which the rolled product (B), which can be transported in a conveying direction (R), can be formed;
• a positioning device (12), which is configured to vary the positioning of at least one of the two working rolls (10) in a plane perpendicular to the conveying direction (R) and to open or close the rolling mill stand (1) accordingly by increasing or decreasing the roll gap (S);
• and
• a location control system (20), which is configured to detect a position of the rolled product (B) in front of and/or behind the roll gap (S) transverse to the conveying direction (R) during the opening or closing of the rolling mill stand (1) and to change the positioning of the at least one of the two working rolls (10) depending on the detected position in such a manner that the rolled product (B) is stabilized at a target position during the opening or closing of the rolling mill stand (1),
• wherein closing the corresponding rolling mill stand (1) includes transitioning the two working rolls (10) from a pulled-up state in which a thickness of the rolled product (B) is not reduced to a lowered-down state in which the thickness of the rolled product (B) is reduced, and
• wherein opening the rolling mill stand (1) includes transitioning the two working rolls (10) from the lowered-down state to the pulled-up state.
