The AIST 2015 North American Hot Strip Mill Roundup was reviewed, which gives an overview of capabilities and equipment. The roundup was published in the November 2015 issue of Iron & Steel Technology.
Hot Rolling Fundamentals — A Practical Training Seminar was reviewed. The conference will be held 21–25 February 2016 in Birmingham, Ala., USA. More information about this conference can be found on pages 148–150 of this issue.
Both committees finalized their AISTech 2017 Call for Papers topics and discussed items to be reviewed at the AIST Leadership Conference.
The producer members were encouraged to utilize the AIST Process Benchmarker® system for benchmarking their processes by entering data into the system.
Technical presentations were given on the following topics:

  • Pickling technology.

  • Eco pickled surface (EPS).

  • iBox technology.

  • Spray nozzle technologies.

  • Overview of Spraying Systems research facility.

  • Advanced high-strength steels (AHSS) (including a roundtable discussion on AHSS best practices).

Producers and suppliers discussed any challenges or successes related to the processing of advanced high-strength steels as related to their equipment.
Both groups toured their respective areas of California Steel Industries Inc. in Fontaine, Calif., USA.

Meeting Highlights:
Feedback was solicited from the HSRTC regarding joint Technology Committee meetings. As a whole, the committee agreed that this is important and would like to continue this trend moving forward, as it provides a valuable benefit not only for networking, but it also gives everyone a different perspective. Future possibilities of joint sessions would be with the Cold Sheet Rolling and Safety & Health Technology Committees.

The HSSC met 1–2 October 2014, Fort Wayne, Ind., USA. The subcommittee held a joint meeting with the Hot Sheet Rolling Technology Committee. Dan Herron, Nucor Steel, explained the details and experiences of Nucor’s system. Brian Smith, Siemens, SSSC chair, gave a presentation on camber gauges, surface inspection devices and width gauges. Chris Burnett, Fisher Scientific, led the discussion on AISTech technical session development. It was decided to have a joint session with the Cold Sheet Rolling Technology Committee and another with the Hot Sheet Rolling Technology Committee. Burnett also discussed the status of the Process Systems Technology Training Conference, to be held 2–5 March 2015 in Mobile, Ala., USA. 
The attendees toured the meltshop, caster and hot strip mill at Steel Dynamics Inc. (SDI) – Flat Rolled Div. in Butler, Ind., USA. On the third day of the meeting, attendees toured the GM Fort Wayne truck assembly facility.

 
The HSRTC held its meeting 30 September–1 October 2014, Fort Wayne, Ind., USA. Fort Wayne, Ind.,Jim Murphy, Quaker Chemical Corp., HSRTC papers chair, reviewed the four HSRTC sessions being planned for AISTech 2015 and solicited volunteers to be session chairs. Eric Thokar, Siemens, HSRTC training chair, discussed the next Hot Rolling Fundamentals course, to be held in Birmingham, Ala., USA, in early 2016. A safety discussion was held related to fighting complacency with an aging workforce. Representatives from steel producing plants gave short presentations on their safety performance, reliability issues/improvements and environmental initiatives.
The second day took place at Steel Dynamics Inc. (SDI) – Flat Rolled Div. in Butler, Ind., USA, as a joint meeting with the Sensor Systems Subcommittee (SSSC). The theme for the presentations was surface inspection systems. Dan Herron, Nucor Steel, explained the details and experiences of Nucor’s system. Brian Smith, Siemens, SSSC chair, gave a presentation on camber gauges, surface inspection devices and width gauges. The attendees toured SDI’s meltshop, caster and hot strip mill.

The attendees toured the GM Fort Wayne truck assembly facility on the third day.

The HSRTC held its meeting 6–7 March 2014, Charleston, S.C., USA. The HSRTC toured Nucor Steel–Berkeley with the Plate Rolling Technology Committee. Nucor had just completed an extensive hot mill “widening” and other modifications. This made the tour even more interesting. The HSRTC thanks Nucor Steel–Berkeley for its hospitality.
Jim Murphy, Quaker Chemical Corp. and HSRTC papers chair, reviewed the HSRTC sessions for AISTech 2014. 
Tom Weiler, Nucor Steel–Indiana and HSRTC AIST Process Benchmarker™ (APB) chair, gave an update on the APB. He explained the system functionality, noted that furnaces were using it heavily and stressed that the hot mill users need to input their information.
Dave Hamblin, Nucor Steel–Berkeley and HSRTC chair, reviewed Hot Flat Rolling Fundamentals — A Practical Training Seminar in conjunction with Plate Rolling Fundamentals Training, which had taken place earlier in the week. The attendees had positive comments as well as some suggestions to improve the course. 
Several members participated in a roundtable discussion on safety, CAPEX projects, reliability issues, improvements and environmental initiatives in their hot mills. These open forums encourage participation and are found to be valuable to all present.

Dan Miller, Duraloy Technologies, gave a presentation on dry versus wet furnace rolls, highlighting the energy and maintenance savings which offset the initial expense. 

The HSRTC held its meeting 15–16 October 2013, Toledo, Ohio, USA. The HSRTC was given a tour of North Star BlueScope on the afternoon of 15 October 2013. The meeting began on 16 October 2013, with Tom Weiler of Nucor Steel–Indiana encouraging the producer members to begin entering data into the AIST Process Benchmarker® (APB) system. With six companies on-board, the main focus now is to put data into the system. Eric Thokar of Siemens reviewed the status of Hot Flat Rolling Fundamentals — A Practical Training Seminar in conjunction with Plate Rolling Fundamentals Training, which will take place 3–6 March 2014 in Charleston, S.C., USA, at the Francis Marion Hotel. The course will finish with a tour of the Nucor Steel–Berkeley facility.
Jim Murphy of Quaker Chemical Corp. reviewed the HSRTC abstract selection and hot rolling sessions for AISTech 2014. Session titles were established and volunteers filled the session chair positions. A long discussion was held about averting commercialism in the technical presentations.
Presentations included: “The Wall — Improving Communication Between the Caster and Hot Strip Mill,” by Chris Davis of North Star BlueScope; “Energy Saving Advances in CSP Tunnel Furnace Rolls,” by Dan Miller of Duraloy; and “RMSTrax — Roll Shop Management,” by Joe Porter of North Star BlueScope, Dan Smith of North Star BlueScope and Ken Hutchison of ASE. The producer members then had an opportunity to share safety initiatives with the HSRTC. 

The HSRTC held its meeting in Tuscaloosa, Ala., on 19–20 February 2013. Randy Patterson of Steel Dynamics Inc. opened the meeting and welcomed the attendees. He also thanked Nucor Steel Tuscaloosa Inc. for hosting a tour of its Steckel mill. Jim Murphy of Quaker Chemical Corp. reviewed the status of the Hot Rolling sessions for AISTech 2013, as well as the session chair responsibilities. Eric Thokar of Siemens VAI discussed the 2014 Fundamentals of Hot Rolling Training Seminar. The seminar will include a track on plate rolling fundamentals similar to that of the 2012 Hot Rolling Training Seminar. The date and location were discussed at length, and the final decision will be coordinated between the training subcommittee and AIST. A brief presentation about the Hot Rolling module of the AIST Process Benchmarker™ was given to help clarify the benefits of using the system. Tom Weiler of Nucor Corp. encouraged all the producers to start utilizing the system. Each representative from a producing company presented information on his mill, with a focus on lockout/tagout procedures and lessons learned from those procedures. The next HSRTC meeting will be held on 6 May 2013 at AISTech 2013 in Pittsburgh, Pa. The HSRTC’s fall 2013 meeting location is yet to be finalized, but topics of discussion will include green initiatives and conservation, fall protection and cooling water.
