Technology Committees

Rolls Technology Committee Activities

The RTC met 30–31 January 2018, Memphis, Tenn., USA. There were 42 members in attendance, 13 of which were producers.
The RTC received nominations for committee officers for the 2018–2019 term.
A healthy discussion centered on a formal presentation given by Lydia Stromei, membership chair, which showed attendance at past RTC meetings. She encouraged everyone to suggest ways to engage more members. Joint meetings, like what the RTC has arranged in the past, are being received with great enthusiasm. And, committee officers are now working on a communication piece, intending to send it to a larger audience with some of the ideas developed during this meeting.
There was a lengthy discussion on future meeting sites, and this included a definite interest for visiting producer sites. A unique feature could include holding these meetings inside the host mills. This would provide an opportunity to open up attendance to more mill personnel, while keeping the travel expenses and time away from the job to a minimum.
The RTC then discussed its technical session for AISTech 2018.
During the tour of Big River Steel, the attendees spent considerable time in the EAF, RH vacuum degasser and slab caster front-end of the operations. Foundations for the second EAF and caster systems were visible and pointed out by mill staff.
A group dinner arranged during the meeting was appreciated for extended networking.
The following presentations were given:

  •  “MORGOIL® Bearings — Upgrades, Maintenance and New Developments,” by Ian Ward, Primetals Technologies.

  •  “Latest Developments in Work Roll Bearings,” by Andrew Layne, SKF.

Paul Fleiner (right), RTC chair, and Heather Creely (left), RTC vice chair, presented a plaque of appreciation to Tommie Kifer (center) for hosting the RTC’s tour of Big River Steel.

The RTC met 26–27 September 2017, Holland, Ohio, USA. Chris Hrizo, papers chair, led the AISTech 2018 session development discussion. The RTC selected session chairs and reviewed session chair responsibilities.
Hrizo also noted that the Rolls Best Paper Award planning was underway and the winner would be awarded during the RTC meeting at AISTech 2018 in Philadelphia, Pa., USA.
The meeting continued with a review of the 2017 Steel Industry Fatalities report and a roundtable discussion.

Other discussion items included: Hot Flat Rolling Fundamentals — A Practical Training Seminar, which will take place in spring 2018; the Hot Sheet Rolling Best Paper Award, which will be awarded for the first time at AISTech 2017; locations for the fall meeting locations were discussed and it was agreed to hold it in conjunction with one of the new specialty training conferences.
The HSRTC brainstormed on topics for future meetings and decided to conduct a survey at the next meeting. The results will guide future planning especially in prioritizing tour locations and lining up quality technical presentations.  
For the RTC, committee officers for 2017–2018 were discussed and elections will take place during the RTC meeting at AISTech 2017.
Lydia Stromei shared membership information and led a group discussion on how to bring in new members like having “mini meet-and-greet” visits at roll shops, allowing members to bring a guest to the meeting, and ways to get more involvement from companies like United States Steel Corporation and ArcelorMittal.
Other discussion items at the RTC meeting included the Rolls Best Paper Award and the RTC’s AISTech sessions; discussion of a Roll Shop Roundup, which was tabled; future meetings, including possible joint meetings with the Safety & Health and Maintenance & Reliability Technology Committees.
Pending confirmations, the RTC’s fall meeting is planned for 22–23 August 2017 in Ohio to tour NorthStar BlueScope Steel, along with a second possible location in the area such as the Jeep plant or Worthington Steel. The technical topic of this meeting will be roll shop management systems and a tentative lineup of presentations was proposed.
The two committees rejoined for the rest of the afternoon for a networking lunch, technical presentations and a plant tour of Steel Dynamics Inc. – Flat Roll Group Columbus.
