Past AIST Committee Activities
The IMTC met on 8 February 2013 at the Embassy Suites Hotel – Pittsburgh Intl. Airport in Coraopolis, Pa. The meeting was held in conjunction with the Eastern States Blast Furnace & Coke Oven Association meeting. The 2012 Steel Industry Fatalities report was reviewed, followed by a safety roundtable discussion. The AISTech 2013 session schedule was reviewed, and two papers were added to the IMTC’s program to fill the remaining open slots. Al Dzermejko provided update on the Ironmaking Best Paper Award Subcommittee, including its roster and task list. It was agreed that the criteria for selecting the Best Paper Award will be revised for next year’s selection and the due dates for this task should be moved forward two weeks. The IMTC mission statement was reviewed and accepted with no changes. The committee then reviewed the AISTech 2014 Call for Papers, adding “furnace relines/rebuilds” to the list of IMTC topics. Officer nominations for the 2013–2014 term include: Kyle Shoop, chair; Chuck Copeland, vice chair and roundup chair; Al Dzermejko, papers chair I; and Michael Riley, papers chair II. The membership chair producer nomination has yet to be determined. The 2012 J.E. Johnson Jr. Award was presented to Daniel J. Holmes of ArcelorMittal Indiana Harbor Flat Products. The IMTC then went on to discuss possible ways to increase producer participation and aims to have at least one ironmaking manager from every U.S. plant involved with the committee. The next IMTC meeting will be held on Monday, 6 May at AISTech 2013 in Pittsburgh, Pa.
The Ironmaking Technology Committee (IMTC) met on 19–20 September 2012 in Dearborn, Mich., at Severstal Dearborn. The meeting was called to order by Bruce Stackhouse, IMTC chair. There were 29 attendees at the two-day meeting, which focused on technical session development for AISTech 2013. The committee established sessions with a wide range of topics, including: operations, raw materials, stoves, alternate ironmaking, environmental, injectants, equipment and devices, modeling, other burden material, and panel discussion topics that include endless campaigns and recovery from furnace wrecks. The second day’s agenda included a presentation and tour of the new pickle line tandem cold mill, galvanizing facility, as well as a tour of the blast furnaces. Both the meeting and tour were hosted by the Ironmaking Department at Severstal. The committee extends special thanks to Ed Asbury, division manager — ironmaking, for the hospitality. The next IMTC meeting was to be held in November 2012 at AIST headquarters in Warrendale, Pa.
The Ironmaking Technology Committee (IMTC) met on 7 May in Atlanta, Ga., during AISTech 2012. The IMTC chair, Bob Steiger, welcomed the committee members in attendance and thanked them for their participation at both the AISTech conference and the IMTC luncheon. Guests and new members were also recognized. It was noted that 39 of the 73-member roster were present. There were three new members to the IMTC. In addition, four Brazilian students were in attendance at the luncheon. The following were nominated as the 2012–2013 IMTC officers: Bruce Stackhouse, chair; Kyle Shoop, Tenova Core, vice chair; Chuck Copeland, Severstal Dearborn, papers chair; Al Dzermejko, Magneco/Metrel Inc., papers co-chair; and Mike Riley, Praxair, membership chair.
The Ironmaking Technology Committee (IMTC) met on 2 February 2012 before the Eastern States Blast Furnace and Coke Oven Association annual winter meeting. There were 39 members in attendance and 12 producer members for the IMTC’s AIST Process Benchmarker (APB) meeting on Thursday morning. Bruce Stackhouse, IMTC producers chair, reviewed the 2011 Steel Industry Fatalities Report, which was followed by a safety roundtable discussion. Several presentations followed, including one from Steve Horvath of ArcelorMittal and Bruce Stackhouse from RG Steel. Bob Steiger (IMTC chair) presided over the general committee meeting that followed. Topics of discussion included:
The IMTC mission statement was reviewed and read as: “AIST Ironmaking Technology Committee shall hold regular meetings discussing and providing members information regarding Ironmaking manufacturing to include developing technologies, maintenance and process and operating information.”
AIST Technical Report No. 33 was submitted for approval by the IMTC. The report was approved with no dissenting votes. This report will now be sent to the Technology Council for approval. Once approved by the Technology Council, the AIST board of directors will vote on the report. Committee objectives for the upcoming year were discussed and additional objectives were solicited. In addition to reaching out to producers to increase their participation on the IMTC, there was a discussion on a joint specialty training conference on refractory use in ironmaking. The following expressed an interest in helping to organize this specialty conference: Bill Slye, Trevor Shellhammer, Art Cheng, Angelo Petrucelli, Hugh Crosmun, Glen Beavers, Jim Weinheimer, Bruce Stackhouse, Bob Steiger, Barry Hyde and Dave Walnoha.
The 2012 Joseph S. Kapitan Award for Best Paper for Ironmaking was awarded to Stuart Street of Severstal Dearborn, Dearborn, Mich., for his paper entitled, “An Investigation of Unstable Blast Furnace Operations Caused by Stockpiled Iron Ore Pellets.” The 2012 Thomas L.

• AIST Technical Report No. 33 (TR-33) final review, led by Bob Steiger and Barry Felton.
The IMTC APB producers subcommittee received an update from Ryan Wolfred of AIST and Jeralyn Brown of Management Science Associates. The Ironmaking APB module has been released to “beta users” for importing of their 2012 data. If you are interested in using the system as a beta user, contact Ryan Wolfred (firstname.lastname@example.org). Following this meeting, members attended the annual winter meeting of Eastern States Blast Furnace and Coke Oven Association.
The Ironmaking Technology Committee (IMTC) met on 14–15 September 2010 at the Holiday Inn in Duluth, Minn. The committee chair, Bob Steiger of Paul Wurth Inc., opened the meeting by welcoming everyone in attendance and thanking Keki Nanavati and Lee English for setting up the following day’s tour at Cliffs Natural Resources. Hugh Crosmun volunteered to take the meeting minutes. The AIST Antitrust Guidelines were reviewed, and it was agreed that the meeting would be held in accordance with them. Mr. Steiger stated that the IMTC membership count stands at 73, as of 12 September 2011. He noted that the IMTC is always looking for more members and asked everyone in attendance to encourage and promote membership, particularly among producers. After the AIST Staff Announcements were reviewed, Bob Steiger addressed the main agenda items for the meeting. During a safety discussion on the 2011 Steel Industry Fatalities Report, it was noted that most of the fatalities were due to burns, falls and crushing situations. Also, of the upstream/downstream fatalities, most were related to workers being struck by moving equipment. It was asked that members share this information with co-workers. A roundtable industry update followed, in which members gave a brief overview their company’s status and operations.
The IMTC papers chair, Kyle Shoop of Tenova Core, led a discussion on AISTech 2012. He gave an overview of the current technical session layout and noted that 53 ironmaking abstracts have been submitted to date. There is a good possibility of having two sessions for each time slot. Joe Poveromo advised to avoid putting sessions with similar interests opposite of each other and that some slight reorganization may be beneficial. Al Dzermejko of Magneco/Metrel Inc. pointed out a lack of producer papers in the conference. The members discussed possible reasons for this, as well as ways to increase the number of papers submitted by producer companies. Further discussions ensued regarding AISTech, and the technical session layout will be reviewed again at the next IMTC meeting. Session chairs will also be established during that meeting. Ryan Wolfred of AIST talked about the status of the Technology Committee Awards. He noted that 16 papers from AISTech 2011 were nominated as Best of Session. Five members volunteered to read, rate and select the best by no later than February. Mr. Wolfred mentioned that AIST Technical Report 33 (TR-33) received over 67% approval and there are still 10 comments that require review by the committee. The comments will be sent to Bob Steiger to be addressed. Fred Rorick, the current U.S. representative on the European Blast Furnace Committee, will be retiring soon and needs someone to replace him. Some discussion took place on the topic, and a replacement has yet to be finalized.
Mr. Wolfred then gave a brief overview of the AIST Process Benchmarker (APB) project. The benchmarking task force has been established and met in July for the first project kickoff meeting. The benchmarking software is in development, with a beta version released in November 2011. APB access and use will be granted to producer members, providing them a tool to easily and effectively compare their production performance against industry peers. For the IMTC, 144 production metrics have been established. The committee reconvened after lunch for a short presentation by representatives from Cliffs Natural Resources. Bob Steiger thanked everyone for their attendance and adjourned the meeting. The following day, Cliffs hosted the members on a tour of their iron ore mine and pellet plant at the Hibbing Taconite facility. AIST and the IMTC would like to thank Keki Nanavati and everyone at Cliffs Natural Resources for their outstanding hospitality.
The first-ever AIST Process Benchmarker (APB) Project Kickoff Meeting was held at AIST headquarters in Warrendale, Pa., on 12 July 2011. The meeting focused on the Ironmaking Technology Committee’s (IMTC) benchmarking efforts; however, selected individuals from AIST’s other technology committees were also invited to sit in on the meeting to get a feel for the capabilities of the APB and to begin planning for their own committees’ benchmarking programs. Brian Bliss, AIST’s technology programs manager, opened the meeting by welcoming and thanking everyone in attendance. He then initiated introductions and discussed the main objectives of the meeting. AIST executive director Ron Ashburn followed with a brief history of the APB, along with some key features and goals of the system. The APB is planned to be in use by fall 2011, beginning with the IMTC, and then moving through various other committees as they become available.
Management Science Associates Inc. (MSA) will be developing the APB for AIST and its Technology Committees. MSA has a wealth of experience in developing and operating benchmarking systems for various industries, and the APB will be based on MSA’s proven raw material data aggregation system (RMDAS) platform. Ashburn concluded his presentation by introducing Pat Gallagher, vice president of MSA. Gallagher gave a brief overview of the APB on-boarding steps and data flow. He also previewed the main items to be covered throughout the meeting. Jeralyn Brown of MSA then gave a brief demo of the RMDAS functionality to give the participants a better idea of the capabilities and flexibility that the APB system will possess. Tim Redmond of MSA followed with a demo of the APB prototype. After a short break, the participants reconvened for a discussion on how the IMTC’s existing benchmarking spreadsheet is used. The ironmaking producers currently track 148 blast furnace metrics, all of which they plan to continue tracking in the APB system.
Following lunch, Pat Gallagher continued the discussion on the benchmarking metrics, and it was agreed that Fred Rorick would provide the most current Excel spreadsheet format to MSA with the formulas for calculated values, as well as the rules and ranges set in place for data validation. Gallagher then led a discussion regarding the APB’s data import procedures. Attendees agreed that data will be input in monthly increments and preferred that the user’s previous 12 months of data be displayed on every import sheet. This will provide users with the ability to correct previously input data if it is later found to be erroneous. Training and support for the APB system was also discussed. Ryan Wolfred, the AIST staff engineer assigned to the APB project, will essentially become a “super user” and handle the majority of training and support necessary for users. In-person training sessions will be held and are recommended for all users; however, training will also be available via Webinars. After a short break, Wolfred led a discussion regarding the establishment of committee-specific APB rules and guidelines. Some such rules include whether a company is allowed to access output data for a certain time frame if they have not yet submitted data for that time frame, the percentage of a company’s modules that need to be current to receive output data and the maxwimum number of missing data fields allowable per input. The final item covered during the meeting was the establishment of an APB system development timeline. Pat Gallagher stated that an exact timeline is still hard to determine at this point, but it may take roughly two months for successful completion of the factory acceptance test. Brian Bliss then thanked all the attendees for their participation and adjourned the meeting.
The Ironmaking Technology Committee (IMTC) met on Monday, 2 May at AISTech 2011 in Indianapolis, Ind. There were 38 members in attendance and the current committee membership count stands at 74.
