Investigation of force parameters during rolling in relief rolls

Abstract

The paper presents the results of theoretical studies of the force parameters of thick-sheet blanks rolling in relief rolls. Empirical dependences were obtained to determine the average rolling pressure and force. When studying the pressure, the approach of replacing the defonnation scheme with a flat analog was used. In the analysis of the force, the finite element method was used to determine the geometric parameters of the defonnation zone. Verification of the obtained dependencies was carried out by comparison with the results of computer simulation. Comparative analysis showed high convergence of the calculation and simulation results, as well as the possibility of applying the fonnulas obtained not only for symmetrical rolling or for speed asymmetry, but also in the case of rolling in relief rolls of different diameters.
