Abstract:
A rolling mill stand for production of rolled strip or sheet metal has working rolls which are supported on supporting rolls or on intermediate rolls and supporting rolls. The working rolls and/or intermediate rolls are arranged in the rolling mill stand so as to be displaceable axially with respect to one another. Each working and/or intermediate roll has a curved barrel contour which runs over the entire effective barrel length and can be described by a trigonometric function. The two barrel contours of adjacent rolls complete one another in a complementary way, in the unloaded state, solely in one specific relative axial position of the rolls of the pair of rolls, so that inhomogeneities in the load distribution along the contact line of two adjacent rolls are to be minimized. For this purpose, the supporting rolls have a complementary barrel contour, and a partial or full completion of the barrel contours of the supporting rolls and of the directly adjacent working rolls or intermediate rolls occurs in the unloaded state.
