Abstract: The invention relates to a method for increasing the process stability, particularly the absolute thickness precision and the installation safety during the hot rolling of steel of nonferrous materials, with small degrees of deformation (f) or no reductions while taking the high-temperature limit of elasticity (Re) into account when calculating the set rolling force (Fw) and the respective setting position (s). The process stability can be increased with regard to the precision of the yield stress (kf,R) and the set rolling force (Fw) at small degrees of deformation (f) or small reductions, during which the high temperature limit of elasticity (Re) is determined according to the deformation temperature (T) and/or the deformation speed (phip) and is integrated into the function of the yield stress (kf) for determining the set rolling force (Fw) via the relation (2) Re=a+eb1+b2·T.phipc, in which: Re represents the high temperature; phip represents the deformation speed, and; a, b, c represent coefficients.
