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.

An arrangement for regulating a four-high rolling mill for rolling metal, said rolling mill having work rolls which are controlled by guided roll shells of a lower controlled deflection roll and an upper controlled deflection roll, the roll shells of which bear against a related roll support by means of hydrostatic pressure elements exerting a pressure therebetween, said regulation arrangement comprising: first regulation circuits for regulating said pressure exerted by said hydrostatic pressure elements; at least one second regulation circuit for regulating the position of said roll shells; said at least one second regulation circuit being provided with means for overriding said first regulation circuits and for impressing adjustment output magnitudes of the second regulation circuit upon the first regulation circuits as adjustment magnitudes; at least one third regulation circuit for selectively regulating either the roll force or the roll nip; and said at least one third regulation circuit being provided with means for overriding the first and the at least one second regulation circuits and for impressing adjustment output magnitudes of the at least one third regulation circuit upon the first regulation circuit as adjustment magnitudes.
