INFLUENCE OF THE INITIAL BILLET SECTION GEOMETRY ON THE MECHANICAL PROPERTIES OF THE PIPES

Abstract

In this work, the process of rolling a continuously cast hollow billet is researched in comparison with the traditional technology for producing hot-rolled pipes: piercing and rolling of a sleeve. The experimental part describes the computer simulation algorithm in the Deform 3D software package and performs a comparative analysis of the deformation results for various types of the initial billet and pressure treatment processes. As a result of modeling, the advantages of the proposed technology for producing seamless pipes were revealed.
