The RSTC met 17 May 2016, Pittsburgh, PA, USA.

The following officers were elected:

  • Chair: Xin Zhang, ArcelorMittal Indiana Harbor

  • Vice chair: Lionel Rebouillat, Pyrotek Canada Inc.

  • Papers chair: Rakesh Dhaka, U. S. Steel Research and Technology Center

  • Education chair: Jimmy Barrett, Allied Mineral Products Inc.

The RSTC and LSRTC met 10–11 February 2016, Mobile, Ala., USA. The 2015–2016 Steel Industry Fatalities statistics were reviewed, followed by a safety roundtable discussion.
The committees reviewed their technical sessions for AISTech 2016. LSRTC has five sessions scheduled, and the RSTC has four. The role of the session chair was reviewed.
Nominations for committee officers for the 2016–2017 term were accepted and approved.
Jimmy Barrett discussed the evaluations from Secondary Steelmaking Refractories — A Practical Training Seminar attendees. Seminar presenters were given their individual appraisals from the attendees.
The LSRTC and RSTC will hold another joint meeting in October in Birmingham, Ala., USA, with a tour of CMC Steel Alabama. The meeting will focus on ladle campaigns/ladle deformation.
The following technical presentations were given:

  • “Technology Update on Laser Monitoring of Metallurgical Vessels,” by Michel Bonin of Process Metrix.

  • “Experiences With Laser Monitoring at SSAB Mobile,” by Greg Manfredi of SSAB.

  • “Latest Techniques in IR Thermal Imaging of Metallurgical Vessels,” by Tom Connors of Connors Industrials Inc.

  • “Experiences With Laser Monitoring at ArcelorMittal Burns Harbor,” by Sanjay Kumar of ArcelorMittal Burns Harbor.

  • “Auto Tracking of Steel Plant Ladles Using RFID-Wireless Systems,” by Federico Ahualli of AustralTek LLC.

The Ladle & Secondary Refining Technology Committee and the Refractory Systems Technology Committee toured SSAB Mobile during their joint meeting on 10–11 February 2016.

The RSTC met 8 October 2015, Memphis, Tenn., USA, in conjunction with Secondary Steelmaking Refractories — A Practical Training Seminar. Lionel Rebouillat reviewed the status of the RSTC’s AISTech 2016 session development. There will be 20 papers presented across four sessions, two of which will be joint sessions with the Ladle & Secondary Refining and Continuous Casting Technology Committees. Volunteers were solicited for session chairs. The responsibilities of the session chairs were reviewed with the group.
The group also finalized its AISTech 2017 Call for Papers topic.
The initial feedback from Secondary Steelmaking Refractories — A Practical Training Seminar was discussed. The additional topics added concerning the tundish were deemed beneficial. There was a discussion of the time allotted to topics and modification of topics to better communicate the relevant information. This was tabled for a later discussion to include the Ladle & Secondary Refining Technology Committee members.

The RSTC met 5 May 2015, Cleveland, Ohio, USA.
The following officers were elected:

  • Chair: Albert Dainton, Vesuvius USA

  • Vice chair: Xin Zhang, ArcelorMittal Indiana Harbor

  • Papers chair: Lionel Rebouillat, Pyrotek Canada Inc.

Meeting Highlights:
The RSTC discussed Secondary Steelmaking Refractories — A Practical Training Seminar. James Barrett reviewed the schedule and gave some details on the sessions on tundish refractories.

The RSTC met 5–6 November 2014, Dallas/Fort Worth, Texas, USA. Xin Zhang, RSTC papers chair, finalized the AISTech 2015 technical session structure for the RSTC.
The group reviewed the RSTC’s description for the AISTech 2016 Call for Papers.
It was decided that the RSTC will establish an annual best paper award to be presented at AISTech. Several members volunteered for this year’s evaluations.
Joe Malchar of Gerdau Long Steel North America Midlothian Mill gave a presentation on historical refractory consumption, current refractory projects, and process key performance indicators that are evaluated relative to refractory performance.
The RSTC agreed to add a section on tundish refractories to its 2015 technology training conference. On Thursday, 6 November, the group toured the Gerdau Long Steel North America Midlothian plant.

The RSTC held its meeting on 11–12 March 2014 in Milwaukee, Wis., USA. There were 24 out of 33 RSTC members in attendance. Albert Dainton, RSTC papers chair, presented the updated list of RSTC papers at AISTech 2014.
Nominations of RSTC officers took place during the RSTC meeting at AISTech in May.
A few ideas were discussed to promote the activities of the RSTC and increase attendance: invitation to plant tour personnel during future meetings, increased promotion of the plant tour, distribution of a newly designed flyer or Web link, and promotion of the technical presentations or discussions held during the meetings.
Kyle Kingsbury created a task force to develop a new specialty training conference on tundish refractories/continuous casting. Members of this task force include: Jim Barrett, Bill Drake and Albert Dainton.
The group toured the Charter Steel – Saukville, Wisconsin plant in the afternoon. They visited the meltshop and hot mill areas of the plant.
The second day of the meeting concluded with a technical presentation from Tom Connors, president of Connors Industrials Inc. He presented an overview of thermographic sensor solutions for managing safety and refractory maintenance for steel and iron ladles.  

The RSTC held its meeting on 25–26 March 2013 in St. Louis, Mo. This occurred during the second-worst snowfall in St. Louis’ history. More than 12 inches of snow fell over a 24-hour period, causing major travel problems and flight cancellations. Despite the weather, 10 committee members braved the cold and attended the meeting. Rob Doty, RSTC chair, conducted the meeting. Dawn Mandich, papers chair, reviewed AISTech 2013 paper and session chair responsibilities. Session chair assignments were reviewed and finalized. The main agenda item included discussion regarding the 2013 Ladle Refractory and Secondary Steelmaking Short Course. The course will be held 30 September–2 October in Charleston, S.C., with the RSTC meeting to follow on 3 October. Additions to this year’s course will include a session on plant safety and process modeling. A discussion followed on possible future additions to the course schedule. Topics were discussed for future RSTC meetings. All RSTC members were asked to submit a recommendation that would not be considered “ethics” issues. On Tuesday, 26 March 2013, the RSTC toured the SunCoke Energy facility in Granite City, Ill. The tour was organized and conducted by Gary West, refractory technology specialist at SunCoke Energy.
