Rolling mill stand with axially slidable rolls

In a rolling mill stand with work rolls which are supported by back-up rolls or by intermediate and back-up rolls, wherein the work rolls, the intermediate rolls and the back-up rolls are axially slidable relative to each other into and out of a neutral position, the rolls having bodies with circumferential lines, the bodies being provided with alternatingly concavely and convexly shaped contours, such that the rolls supplement each other in at least one axial position of the rolls so that no gap exists between the rolls, wherein corrections of the roll gap between a pair of rolls are carried out by relative axial displacement of the rolls, the improvement comprising the contours of each of the rolls having in the neutral roll position thereof, in addition to a possible maximum in the middle, maximum inclinations of the circumferential lines on both sides of the middle of the circumferential surfaces of the rolls in longitudinal direction of the rolls in which roll gap profile changes are to be effected, wherein the contours of the rolls correspond in dependence upon the radius r from the respective axial position x to the equation

• r.sub.(x) =a+bx+cx.sup.2 +dx.sup.3 +ex.sup.4 +fx.sup.5
• wherein the contours are determined by inserting given preferred fixed values into this equation.
