Abstract

The paper presents the results of the outer surface quality examinations of Zr-1%Nb alloy tubes after the process of pilger rolling with a deformation of ε=72% on a KPW rolling mill. For the analysis of the effect of the strain rate and the degree of deformation of the magnitude of the yield stress σp of the investigated alloy, an experiment was programmed based on the industrial conditions and physical modelling of the rolling process was carried out. For the physical modelling of the process under examination, the GLEEBLE 3800 metallurgical process simulator was employed. Based on the examination results, the relationship σp= σp(ɛ, έ) has been obtained for discontinuous cold deformation conditions and recommendations for the division of the strain distribution over the deformation zone length have been given.

Keywords: numerical modelling, physical modelling, asymmetric rolling, micro-additive low-carbon steels
