FE Analysis of Roll Wear during Railwa y Rail Rolling Process

Abstract

The article presents the development of new roll pass designs for rolling of the MAV48, P50 and 50E2 railway rails under the production conditions of the D-815 rolling mill at ArcelorMittal Poland S.A. The aim of the study was to design, using computer simulations, a roll pass geometry ensuring the required dimensional accuracy of the final product while minimizing roll wear and ensuring stable rolling conditions. The roll pass design was developed using a CAD computer program, which enabled precise modeling of pass geometry and their arrangement in the rolling mill. The developed solutions were verified using numerical simulations, and then implemented in industrial conditions for production. The obtained results confirmed the correctness of the design assumptions and indicated the possibility of implementing the developed roll pass system in industrial practice.
