Abstract:
A regulation device (7) for a rolling stand (2) has a force regulator (8) and a position regulator (9) mounted underneath the force regulator. During operation of the regulation device, a rolling force target value (F*) and a rolling force actual value (F) are supplied to the force regulator (8). A regulating distance correcting value (ds1*) is determined by the force regulator (8) from the rolling force target value (F*) and the rolling force actual value (F). The regulating distance correcting value (ds1*), an excentricity compensation value (ds2*), and a regulating distance actual value (s) of a regulating element (6) are supplied to the position regulator (9). A correcting quantity (dq) is determined by the position regulator (9) from the values (ds1*, ds2*, s) supplied thereto and is delivered to the regulating element (6). The regulating distance of the regulating element (6) is changed according to the correcting quantity (dq).
