In 2020, preparations for the 6th Roll Conference “Rolls 6” had been in full swing, when regretfully IOM3 had to announce a postponement and eventually the cancellation of the event, due to the continued uncertainty surrounding the Coronavirus (COVID-19).

From the superb full conference programme scheduled for Rolls 6, we are now offering a selection of papers in a special series of Rolls for Metal Rolling Online Seminars. Presenters from research institutes and from the roll-making and roll-using industries will present the latest advances and new challenges in rolls technology developments, from scientific as well as industrial perspectives.



A concise and powerful format

Split across 4 individual sessions, each two-hour webinar will concentrate on a sub-theme of rolls technology through dedicated contributions from reputed speakers.
All sessions are free to attend, to view the programme and register please click on the individual sessions below

Session 1: Rolls for Hot Rolling

9 June 2021 | 13:00 - 15:00 BST 

Four speakers from 3 continents will present developments and field experiences with advanced rolls for hot rolling applications, ranging from plate mills and hot mill roughing stands to early and late finishing stands. Each paper will provide a unique perspective, from varying viewpoints of roll manufacturers, roll users and research institutes, on establishing reliable rolls across the mills, roll damage modelling, and collaborative research for and implementation of advanced roll grades in hot strip mills.

Session 2: Roll surface treatments & assessments

23 June 2021 | 13:00 - 15:00 BST 

Two papers will deal with coatings on work rolls. The first paper presents a new, environment-friendly trivalent chromium-based plating process as possible replacement of the common hexavalent hard chrome process, illustrated with field experiences. The second paper proposes electroless nickel dispersion coatings with a broader field of application, including cold mill and hot mill rolls. New developments in roll surface texturing will be discussed in the third paper. The final paper in this session, from a broad consortium, will present a project enabling mill operators to perform fast roll surface analyses directly at the end of a rolling campaign, using tablets with quick measurements.

Session 3: Modelling & Roll Life Optimisation

7 July 2021 | 13:00 - 15:00 BST 

Four speakers will present computational methods and modelling results to optimise roll life and value-in-use in various rolling applications. The first paper focuses on long product mill rolls, presenting a new theory to predict the minimum safe working diameters. In the second paper, a complex design approach is proposed aiming at back-up roll life optimisation. The third paper will feature an FE-model to optimize the roll life in reversing roughing stands. The final paper deals with hot strip finishing mills, showing examples of a numerical approach to calculate effects of strip and roll cooling parameters and roll material properties on in-use behaviour of work rolls.

Session 4: Enabling technologies to boost roll & mill performance

21 July 2021 | 13:00 - 15:00 BST 

Various technology providers will expound several types of technologies and strategies geared towards boosting roll and mill performance. The first paper will focus on enhanced Ultrasound inspection technology for optimal detection of defects in rolls. The second paper will present concepts and strategies to optimise VIU of universal sleeves for section mill rolls. The third paper will explicate how continual development over decades of roll shop hardware and systems have evolved into a ‘Digital Roll Shop’ with a fully integrated suite of software based functions. Lastly, a novel grinding approach will be revealed to tailor work roll surface topographies to specific rolling applications.
