The Rolls Technology Committee (RTC) held a meeting Sept. 16–17 in Columbus, Miss., with a tour of the Columbus Roll Shop and Severstal Columbus (formerly SeverCorr). The tour began the morning of Sept. 16 and started with the cold mill roll shop, followed by the hot mill roll shop. During the tour, the attendees had the opportunity to see the roll grinders, the electric discharge texturing (EDT) machine and the chroming process. This was followed by a tour of Severstal Columbus, where attendees followed the process from the caster through the hot mill. The RTC then went through the pickler and the 5-stand tandem cold mill. The hydrogen annealing bases and the temper mill completed the tour. After lunch, Jim Senne moderated a round table discussion on alternate methods and procedures to extend roll life. Presentations were made by various committee members, with discussion following each presentation. The next day, the committee planned their sessions for AISTech 2009 in St. Louis, Mo. The RTC hopes to conduct a joint session with the Safety and Health Technology Committee on roll shop safety. After selecting papers for AISTech, the RTC identified session titles and session chairs. They then discussed membership on the committee and identified companies to target for participation. An update on the 2008 Leadership Development Conference was provided. This was followed by open discussion, including a couple options for the next RTC meeting. They also discussed the possibility of a European meeting in 2009.
The Roll Technology Operating Committee (RTOC) met in Pittsburgh, Pa., on May 7 at AISTech 2008. The meeting began with the presentation of the RTOC’s Best Paper Award to Eugene Nikitenko for his paper, “Hot Band Profile Irregularities Related to Thermal Contour of Work Rolls.” The status of the integration plan for the AISI committees was then discussed, and the name of the committee was changed to the Rolls Technology Committee (RTC). They also discussed coordinating some of their efforts with the Hot Sheet Rolling Technology Committee and the Cold Sheet Rolling Technology Committee. They were pleased with the attendance at their AISTech 2008 sessions and with the quality of the presentations, and made plans to discuss potential changes for future sessions. Officer elections made Tony Payling the chair, Jerry Bunnell the vice chair and Kalyan Khan the papers chair. Their mission statement was modified to include roll manufacturing and also roll shop operations and safety. They then developed their potential meeting sites for the upcoming year and discussed the possibility of a European tour in the fall of 2009. Topics and presentations for upcoming meetings were also identified. Some of these topics include how users can ensure roll availability via roll repair techniques, achieving maximum useful roll life, roll shop safety and environment, handling of grinding wheels, and crane safety.
January 15-16 , 2008 - The Roll Technology Operating Committee (RTOC) met on Jan. 15–16 in Decatur, Ala.

The committee wants to begin looking further into the future to plan their AISTech sessions, so that they might increase the number of sessions they offer and improve the sessions’ quality. Kalyan Khan provided an update on the paper selected for the “Best Paper Award.” A review of the committee membership was held, along with a discussion of a letter that Joe Kirwin has been using to recruit new RTOC members. Tony Payling talked about his participation in the meetings with AISI Manufacturing Committees and their integration into AIST. There was also discussion on identifying committee members to be liaisons with other AIST committees, such as the Sheet Rolling Operating Committee and the Plate Rolling Operating Committee. The meeting included guests from the Institute of Roll Design (IRD) to discuss the possibility of some collaborative efforts. As an initial step, it was decided to begin listing the IRD meetings on the AIST Steel Calendar, and to consider the possibility of co-locating future meetings. Mike Miller gave a presentation on the Nucor Steel–Decatur tours that would take place the next day. On Jan. 16, the members toured the Nucor Decatur cold mill, including the roll shop, 4-stand cold mill and the temper mill. This was followed by a tour of the hot mill. Mike Quig gave a tour of the NEO Industries plant, which textures and chrome-plates many of the rolls for Nucor Decatur. At NEO, RTOC members had the opportunity to see the electrodischarge texturing (EDT) machine and the chrome depositor. After the tour, the RTOC reconvened for Klaus Guip’s overview of the new roll shop at the Thyssen Krupp greenfield site. This was followed by open discussion pertaining to roll shops of the future.
September 5-6 , 2007 - The Roll Technology Operating Committee (RTOC) met in Hamilton, Ont., Canada, on Sept. 5–6.

He encouraged everyone in attendance to discuss this when they are making contacts. The RTOC then identified papers and sessions for AISTech 2008, which will be held May 5–8 in Pittsburgh, Pa. It was decided to have sessions on “World Trends in Roll Shop Design and Modernization,” “Roll Inspection and Measurement” and “Roll Performance.” Two papers from AISTech 2007 are being considered for the RTOC Best Paper Award. The idea of future joint sessions with some of the rolling committees was discussed and will be pursued. There were three technical presentations and a short video previewing the theme, “World Trends in Roll Shop Design and Modernization.” Jessica Van Soelen, Karl-Heinz Adamek and Tony Payling gave presentations, and Larry Hiller narrated a video by Herkules. A tour of the Lake Erie Steel hot mill and roll shop followed, and Ms. Van Soelen commented that it would be interesting to compare the roll shop now and after the modernization is completed.
May 8, 2007 - The Roll Technology Operating Committee (RTOC) held a meeting at AISTech in Indianapolis, Ind., on May 8. They reviewed their mission statement: “To improve the understanding of all aspects of rolls, including roll usage, roll metallurgy, roll preparation and roll inspection. The committee will achieve these goals by organizing seminars, symposiums and tours, creating literature, and providing a forum for discussion and networking.” It was determined that the mission statement still meets the committee’s goals. The RTOC membership chair, Joe Kirwin, presented an update on committee membership. He expressed an interest in growing the committee membership and encouraged the members to solicit new members. New officers for the upcoming year were then elected. John Gordon was elected chair; Tony Payling, vice chair; and Kalyan Khan, papers chair. They then discussed and finalized their topics for AISTech 2008, with one theme being “Roll Cracking, Inspection and Performance,” and a technical session and round table theme of “World Trends in Roll Shop Modernization.” The schedule for AISTech 2008 was reviewed, and it was noted that July 31, 2007, is the deadline for submission of abstracts. Future meeting plans were discussed, along with topics for round table discussions at these meetings.

Division to identify the division awards. There was also some
discussion on the importance and activities of a membership subcommittee,
and this was settled upon as an option worth pursuing. The format
of the committee meetings held so far was reviewed, with the general
consensus that the current method is working very well. A round
table discussion on roll and roll shop tolerances followed the
business meeting, with presentations and open discussion. Testimonies
were given on the value some committee members received from participating

provided. A review of their meeting format indicated that their
approach of scheduling technical presentations and roundtable discussions
in conjunction with their AIST business meeting and a plant tour
provided value to those attending the meetings. The afternoon included
technical presentations by producers and suppliers on roll inspection
