Abstract: | This paper presents finite element modeling of various options for implementing the asymmetry factor during rolling in relief rolls. Models of kinematic asymmetry (with different roll rotation speeds), geometric asymmetry (with different roll diameters), and contact asymmetry (with different friction coefficients of the rolls) were considered. For a comparative analysis, the shape change in the longitudinal and transverse directions, equivalent strain, Mises strain, equivalent stress, average hydrostatic pressure, and deformation force were considered. The simulation results showed that contact asymmetry is the least effective option, where the simulation results for all parameters are very close to those of the symmetrical rolling process in relief rolls. Kinematic and geometric asymmetries have shown good results in terms of the development of additional shear deformation in the longitudinal direction. The final scheme of the process must be selected based on the actual technological data of the rolling mill. |
