Examination of energy and force parameters during rolling process using longitudinal slitting passes

Article preview

Bar rolling with longitudinal strip cutting requires the use of special mathematical models to account for metal tearing. For numerical modeling of the strip cutting process and calculation of energy and force parameters, the Forge3® computer program was used. Strip separation is performed by means of separating rollers, the shape of which must be properly designed according to the longitudinal rolling pass. In the strip separation rolling process, the separating rollers are not driven. The energy and force parameters required to rotate the rolls are determined by the driven working rolls. Therefore, empirical dependencies known from the literature for the calculation of energy and force parameters cannot be used to correctly determine these parameters when rolling strip in the slitting pass and during the separation itself. The use of FEM-based computer programs for solving problems of plasticity theory allows not only to determine energy and force parameters in complex plastic processing processes, but also to take into account a number of process features that are not taken into account by empirical formulas.
