Abstract
A method for changing rollers in a roll stand adapted for bearing at least one working roller for a continuously-running steel-strip roll mill, includes providing the stand as part of a plurality of roll stands disposed in series along the roll mill in a continuous running direction. A rolling standby function in a free clamping position of the roller(s) is allocated to at least one dedicated stand among the plurality of stands. Original setpoint values controlling an adjustment of the roller clamping are individually allocated to the other stands in an active rolling position. In the case of a roller change when passing into the free clamping position of the stand, the original setpoint value of the stand and the original setpoint values of the stands remaining in an active rolling position are redistributed individually among each of the stands, including the dedicated stand.
