Abstract

The properties of steel rod are functions of the composition and various microstructural parameters and the latter are strongly influenced by the rolling conditions. A knowledge of the evolution of microstructure during rod rolling is prerequisite to determining the influence of the changes in rolling practice. The primary aim of the current programme was to study the evolution of microstructure through the finishing stands of a rod mill. Thus the input microstructure is that emerging from the last stand of the intermediate mill. Since the development of a mathematical model to describe the evolution of microstructure requires a knowledge of the various rolling parameters that affect microstructure, it was necessary to couple it to a finite element model for multi-pass rod rolling. The various stages in the evolution and factors affecting the final rod microstructure are shown. The programme also included validation of the models using a hot deformation simulator and laboratory and commercial rod rolling trials. The programme has been developed primarily for the rolling of austenitic stainless grades 304 and 316 in a modern rod finishing block mill. Brief consideration has also been given to 1% C-Cr steel. The results of this research programme are presented in this report.
