Cory Raimondi, ArcelorMittal and PRTC papers chair, reviewed the PRTC session for AISTech 2014 with six presentations on plate rolling technologies. He re-emphasized that the session chairs needed to stay in touch with the authors to ensure the session stays on topic without any commercialism.
Bob Spangler, ArcelorMittal and PRTC chair, led a discussion to encourage others to become leaders in the PRTC by volunteering to be nominated for committee leadership. Nominations of PRTC officers took place during the PRTC meeting at AISTech in May.
Eric Thokar, Siemens Industry Inc. and PRTC training chair, led a discussion to review the feedback about Hot Flat Rolling Fundamentals — A Practical Training Seminar in conjunction with Plate Rolling Fundamentals Training, which took place earlier in the week. Although the feedback was very positive, the attendees identified areas that need to be revisited for the next conference, including a change in venue and “updating the presentations. He also solicited others to help plan the next training conference, which will take place in 2016.

Hodgson Award nomination procedure was discussed. Steve Reese and Dan Elwood will develop criteria for this award and present it at the next meeting. Dan Elwood reported that the Plates Manual appears to be correct and sufficient and, therefore, should be published. The Plate Mill Roundup status was discussed. All data needs to be submitted by the February/March pre-meeting. Currently, it is approximately 60% complete. It was stressed that a total committee effort is needed in order to achieve this deadline. The AIST Process Benchmarker status was also discussed.

The consensus was to establish a subcommittee comprised of Eric Thokar of Danieli, Dan Elwood, Charlie Romberger of ArcelorMittal, and Rich Smith. Their directive is to establish a 3- to 4-hour curriculum that is not covered in the Hot Rolling Fundamentals Course, yet can be given as a breakout session or as an extension at the course. Some of the subjects could be heat treating, leveling and shears. Charlie Romberger is heading up the push to update the Plate Mill Roundup with the assistance of Eric Thokar. Dave Bennett presented a plaque to Rich Smith for his dedicated leadership as PRTC chair this past year. The next meeting is scheduled for 8–9 Sep 2010, at EVRAZ Oregon Steel Mill.
The Plate Rolling Technology Committee (PRTC) met in Birmingham, Ala., on 24–25 Sep. Committee chair Rich Smith of ArcelorMittal Coatesville welcomed the attendees. The attendees introduced themselves and gave a brief update about themselves and their companies. Miles Brittain of Evraz Oregon Steel Mills Inc. volunteered to take the meeting minutes. The AIST Anti-Trust Guidelines were read and agreed upon. The 2009 Steel Mill Fatality Report was distributed and reviewed for the 2009 fatalities to date. It was noted that 2009 has seen a decline compared to 2008. Each of the producing mills summarized their respective safety programs that are in place to improve safety performance. A list of the abstracts for AISTech 2010 was reviewed by the papers chair, Dave Bennett of Evraz Oregon Steel Mills Inc., with recommendations. After discussion it was recommended that a joint session be sought with the Metallurgy — Process, Products & Application Technology Committee. The PRTC will sponsor a half-day session on Tuesday and will include a review of plate rolling history at the Coatesville facility in honor of their 200th anniversary. A significant amount of discussion occurred on the nature and extent of the benchmarking program. A subcommittee was formed to evaluate the latest technical roundup information, along with a rough outline that currently exists. Charlie Romberger of ArcelorMittal R&D will chair the subcommittee, along with Larry Charbonneau of George Kelk Corp., Eric Thokar of Danieli Corp., Mr. Smith of ArcelorMittal Coatesville, and Dan Elwood of ArcelorMittal Burns Harbor. Once a draft is reviewed, it will be distributed to the other producers for review.

Mr. Brittain summarized a productivity upgrade at the Evraz Oregon Steel heat treat line completed in 2008. The nature and extent of a plate-specific training seminar and whether it should stand alone or be integrated into the Hot Rolling Fundamentals Seminar was discussed. It was determined that it is too late to attempt to integrate into the early 2010 session; however, it may be possible, depending on attendance, to schedule another one in 2011. The chair expressed his appreciation to the personnel of Nucor Steel Tuscaloosa for their efforts in arranging and conducting a tour of their facility in conjunction with the PRTC meeting. The next PRTC meeting is scheduled for the week of 22 Feb 2010, at Evraz Oregon Steel – Portland.

The committee presented Mr. Smith with the Norman D. Hodgson Award in recognition of his outstanding contribution to the industry and the PRTC. The mission statement was reviewed and approved as written: “To promote advancement in safe plate rolling and quality practices, operating technologies and processing through information exchange.” The committee agreed that a Plate Mill Roundup should be pursued to gather data regarding North American plate mills. The roundup would allow opportunities for part sharing/sourcing and exchanges of operational issues/upgrades. Mr. Cousins was presented with a plaque to recognize his service as outgoing PRTC chair. It was agreed that the next PRTC meeting will be held at Evraz Oregon Steel in the fall. Depending on the economy and resulting responses for attendance at this meeting, Nucor Steel Tuscaloosa will be considered as a possible second choice. Discussions will focus on reheat technology regarding reheat furnace upgrades at Oregon and Alabama.
The Plate Rolling Technology Committee (PRTC) met 3 Mar in Brighton, Mich. Charlie Bender of NSK Corp. welcomed everyone attending the meeting, as well as those calling in, and thanked them for participating. The AIST Antitrust Guidelines were reviewed, and the AISTech 2009 PRTC sessions were then discussed.

The session chairs were encouraged to contact the authors within their sessions and discuss with them their responsibilities and upcoming deadlines for participation. The PRTC topic for the AISTech 2010 Call for Papers was reviewed and updated. The consensus was to have a session on reheat furnaces at AISTech 2010, since both Nucor Steel Tuscaloosa and Evraz Oregon Steel Mills recently completed the installation of reheat furnaces at their facilities. The PRTC thanks Allor Manufacturing for allowing them to tour their facility on 4 Mar. The next PRTC meeting will be held 5 May during AISTech 2009 in St. Louis, Mo.
