Process for increasing the stability of the process, especially the absolute accuracy of the thickness and the safety of the installation, when the hot rolling of steel or non-ferrous materials a process to increase the stability of the process, especially the absolute accuracy of ES Pessura and safety of installation.When the hot rolling of steel or non-ferrous materials with small degrees of deformation sym or small damage under consideration of the limit of hot stretching (R ~ and ~) when calculating the theoretical rolling force (F ~ W ~) and its launch position (s). Can be improved on the accuracy of the voltage of fluency (K ~ f.R ~) and the strength of the lamination theory (F ~ W ~) to small degrees of degormau00e7u00e3o ( sym or small clearings in the limit of hot stretching (R ~ and ~) is determined as a function of the deformation temperature (T) and / or the speed of deformation (PhIP) and integrated the function of The tension of fluency (K ~ F ~) for the determination of the theoretical rolling force (F ~ W ~) through the relation (2) ru00ac eu00ac =+ and u00acb1 + B2. Tu00ac. Phipu00ac cu00ac where: R ~ and ~ = limit stretch the hot t = temperature of deformation PhIP = speed of deformation a; B; C = coefficients
