OptiRoll - Tools for optimised rolling of long products

Published: 24 January 2017

Wire rolling mills are facing a challenging market situation including the competition from new and low price suppliers, decreasing production volumes and a complex product mix. The solution for a better competitiveness is to continue to upgrade the product mix, and to further increase the productivity. The future need is user-friendly simulation tools which can be utilized by the process engineer for studying and optimizing the process routes. The aim is to develop such simulation tools to facilitate fast and easy exploration of cooling strategies, roll pass designs and mill layouts. Reliable simulations require high quality material data relevant to the particular conditions occurring during high speed rolling of long products.

To meet this need, flow stress, recrystallization, and grain growth characteristics during high rate hot deformation will therefore be generated. Proposed rolling optimisations will be studied by finite element analyses, pilot-scale trials and full industrial scale verification. The project is funded by VINNOVA within the program SIP – Metallic materials 2013-2016 and is run in collaboration with Swerea MEFOS (projektledare), Swerea KIMAB, Fagersta Stainless, Sandvik Materials Technology, Erasteel Kloster, Morgårdshammar and ABB.
