Cross-rolling unit and method for adjusting a roll gap

An adjustment method for adjustment of a roll gap of rolls of a cross-rolling unit operating under load comprising a force-absorbing roll stand and a subassembly disposed on the force-absorbing roll stand comprising a mechanical setting unit for a first cross-roll setting and a hydraulic setting unit for a second cross-roll setting, wherein the mechanical setting unit comprises mutually displaceable first and second mechanical subassemblies having a common axis of symmetry, wherein the first mechanical subassembly is a spindle, wherein the hydraulic setting unit comprises mutually displaceable first and second hydraulic subassemblies having a first central axis and a second central axis, respectively, wherein the axis of symmetry and the first and second central axes are identical, and wherein the spindle is joined via a spindle thread directly with a piston of the second hydraulic subassembly, the method comprising:

• (a) adjusting the roll gap by the mechanical setting unit and the hydraulic setting unit;
• and
• (b) (i) transferring a rolling force acting on the rolls from at least one of the rolls firstly to the hydraulic setting unit, then transferring the rolling force by the hydraulic setting unit to the mechanical setting unit, and thereafter transferring the rolling force by the mechanical setting unit to the roll stand;
• or
• (ii) transferring a rolling force acting on the rolls from at least one of the rolls firstly to the mechanical setting unit, then transferring the rolling force by the mechanical setting unit to the hydraulic setting unit, and thereafter transferring the rolling force by the hydraulic setting unit to the roll stand.
