Technology Committees


Direct Reduced Iron Committee Activities

The DRITC met 7 September 2019, Milwaukee, Wis., USA.

The committees reviewed the 2019 Steel Industry Fatalities report, followed by a safety roundtable discussion. Several topics were discussed, including:

  • Mobile equipment incidents.

  • Radio frequency identification/worker position location monitoring.

  • Lockout, tagout — but also try-out.

  • Avoiding complacency.

  • Keeping the workforce trained not only on “what to do” but also “why to do it this way.”

The DRITC and ESTC discussed their technical sessions for AISTech 2020. There was a brief review of the abstracts submitted thus far. In general, the opinion was that both committees needed more papers. There was discussion of a joint DRITC/ESTC session, as well as a roundtable discussion. Volunteers were taken for session chairs.
The committees spent a significant amount of time discussing AIST’s Young Professionals programming. Young Professionals are the most rapidly increasing group in the AIST membership demographic. The idea of having a committee- and/or Member Chapter-level Young Professional chair position was introduced. Discussions then focused on how to attract more participation from Young Professionals. 
The committees then discussed the EAF and DRI Roundups, which are published annually in the January issue of Iron & Steel Technology. The discussion included expanding the DRI Roundup to include more international companies.
Modern Electric Furnace Steelmaking — the 26th annual edition of the EAF seminar — will be held 3–7 February 2020 in Portland, Ore., USA. A tour of Cascade Steel Rolling Mills will be offered.
Scrap Supplements & Alternative Ironmaking 8 will be held 2–4 March 2020 in Orlando, Fla., USA.
The winners of the 2020 Charles Briggs Award and John Bell Award were selected. These awards will be presented at AISTech 2020 in Cleveland, Ohio, USA.

Presentations:

  • “Pre-Heating of DRI While Charging Into an EAF,” by Greg Buragino, Air Products — The benefits of charging hot DRI have already been documented at meltshops where the DRI process and EAF are closely connected. However, at many locations, DRI is imported, stored and charged cold. Pre-heating the DRI during conveyance from the storage silo to the EAF can have obvious advantages, such as decreased melt time and reduced kilowatt-hours. This presentation provided an alternative method for pre-heating DRI while charging the EAF.

  • “Understanding the Fundamental Aspects of DRI/HBI Melting in the EAF: A Monologue of Zane’s Deepest Inner Thoughts,” by Zane Voss, CIX LLC — There has been a great deal of research on the melting of DRI and HBI in the EAF over the past several decades. This research has been both academic and industrial in nature and has yielded some very interesting results. The presentation summarized this work and compiled it into a comprehensive view of DRI/HBI melting in an industrial setting.

  • “Update on ASTM Standard E1031,” by Thomas Battle, extractive metallurgy consultant — This discussion focused on the current status and needs relating to the reinstatement of ASTM Standard E1031, Standard Test Method for Analysis of Iron-Making and Steel-Making Slags by X-Ray Spectrometry.

  • “A Review of Changing Iron Ore Demands for Ironmaking Technologies,” by Boyd Eisenbraun, Barr Engineering — This presentation provided background information on iron ore, quality, environmental and logistical challenges, and the future of iron production and how that relates to EAF steelmaking.

The DRITC met 7 May 2019, Pittsburgh, PA, USA.

The group met at ArcelorMittal Global R&D for a tour of the facility on 5 March 2019. The following day, the DRITC held its business meeting.
To start the meeting, the Steel Industry Fatalities report was reviewed, followed by a roundtable discussion. Specific challenges of DRI plant safety were highlighted. As plants get older, maintenance isn’t that process-specific. Material handling was also discussed, as well as ways to advocate for more safety training within the DRI community.
The DRITC finalized its AISTech 2019 technical sessions and the roles of session chair and papers chair were reviewed.
There was discussion regarding including presentations in the AISTech Conference Proceedings. It was noted that many presenters who send presentations instead of papers don’t want to be published. A suggestion was also made to consider some market-oriented presentations. 
Nominations for DRITC officers for the 2019–2020 term were taken.
There was discussion on producer involvement and how to get more people involved in the committee.
The Scrap Substitutes and Alternative Iron seminar will be held in Spring 2020 in Orlando, Fla., USA. Jan van der Stel from Tata Steel R&D is the primary organizer for this conference. Presentations will focus on developmental technologies, and are intended to be on a higher technical level. 
The DRI & HBI: Logistics, Production and Utilization seminar is scheduled for Spring 2021. This is an introductory class that focuses on operations.
The following technical presentations were given:

  • “A Global Overview of ArcelorMittal’s DRI Technologies,” by George Tsvik, ArcelorMittal Global R&D – East Chicago.

  • “Laboratory Study of Reduction Kinetics in a DRI Shaft Furnace,” by Mahdi Farahani, ArcelorMittal Global R&D – East Chicago.

  • “The Use of DRI at Electric Arc Furnace (EAF),” by Mike Lowry, ArcelorMittal Research Laboratories.

The DRITC met 12–13 September 2018, Montreal, Que., Canada. The DRITC discussed the session layout for AISTech 2019 in Pittsburgh, Pa., USA, and reviewed the DRI Roundup, which will be published in the January 2019 issue of Iron & Steel Technology.
The committee had the pleasure of listening to three presentations by their attendees:

  •  Justin Farley presented on 45 years of continual improvement at ArcelorMittal Contrecoeur’s DRI modules, which have led to >98% uptime at the facility. The two DRI modules now operate at 145% and 165% of their original designed capacity.

  • Mark Stuckey of Magna Ceramics & Catalysts gave interesting insights into the development of novel catalyst materials for Midrex gas reformers and other types of steam reformers.

  • Elaine Chen’s presentation, titled “Correlations of Raw Materials Lab Tests and Industrial Data,” discussed an extensive series of trials on iron ore pellet samples to correlate laboratory test result data and actual DRI module performance.

The second day the group met at ArcelorMittal Contrecoeur, where Michel Germain and Justin Farley reviewed the plant layout and led the group on a tour around the facility from the port to the DRI modules.
