An arrangement for regulating a rolling mill for metal rolling, the work rolls of which are supported by guided roll shells of a lower controlled deflection roll and an upper controlled deflection roll, the roll shells being supported by means of hydrostatic pressure or support elements upon a related roll support or beam. First regulation circuits are provided for regulating the pressure of the pressure or support elements of the controlled deflection rolls. A second regulation circuit for the position of the roll shells overrides the first regulation circuits, so that adjustment output magnitudes of the second regulation circuit can be impressed as reference or set values or adjustment magnitudes upon the first regulation circuits. There is also provided a third regulation circuit for the rolling force or the roll nip which overrides the second regulation circuit, so that the adjustment output magnitude of the third regulation circuit can be impressed as a reference or set value or adjustment magnitude upon the second regulation circuit.
