Abstract
Modern technology of bar rolling in many cases is based on the application of single or multiple longitudinal slitting, so-called Slit Rolling (SR). The slitting process uses special passes and guides to prepare, shape and separate the incoming billet into two or more individual strands, which will then be further rolled into finished sizes. The essence of this method is the application of two or three consecutive cutting-in passes, in which deformations of metal considerably differ from those occurring in conventional stretching passes. In order to assess deformations in the slitting passes, finite element method has been applied in the essential part of the analysis. The computations were based on the assumption of thermomechanical model of deformation. The analysis of the influence of shape and width of slitting "knives" was performed with varying technological parameters. In particular, three values of relative height of slitting "knife", three different shapes of "knife" as well as three different widths were analysed. Furthermore, physical modelling of the deformation in both slitting passes was realized with application of Gleeble simulator. The stress-strain characteristic of steel at relatively high strain rate condition was obtained. As a result of calculations, the complete metal flow patterns in the slitting passes were determined. The graphs presenting the distributions of stresses and strains in the deformation zone allow direct analysis, which gives better information about the phenomena in the roll gap. The obtained results allowed, in consequence, to design slitting passes more precisely and to better use slit rolling method in rolling mill.
