The IMTC met 11–12 September 2019, Dearborn, Mich., USA.
Nancy Armstrong led the discussion on the IMTC’s AISTech 2020 technical session development. At the time of the meeting, the IMTC had 69 papers. There was a noted increase in the amount of papers on sinter.
One topic of discussion related to papers was the criteria used to decide if a paper is too commercial. The attendees noted it’s hard to judge from the abstract itself. It was recommended that session chairs read the papers to review and check for excess commercialism.
A conference call will be scheduled for the beginning of November for discussion on session structure and session chairs. The instructions for both papers chair and session chair were reviewed.
The IMTC then updated its Call for Papers for AISTech 2021 to remove the language concerning DRI/alternative ironmaking technology.
Planning commenced for the IMTC’s 2020 awards — the Josef S. Kapitan Award, the J.E. Johnson Jr. Award and the Thomas L. Joseph Award.
Scrap Supplements & Alternative Ironmaking 8 will be held 2–4 March 2020 in Orlando, Fla., USA.
Nancy Armstrong then discussed AIST’s Young Professional programming and the initiatives to bring Young Professionals into the industry and keep them. A steering committee has been organized to take ideas from the Young Professionals’ Roundtable at AISTech and create opportunities for young people of any background.
Technology Committees have been asked to explore creating a Young Professional chair position. Megha Jampani from Praxair will serve in this capacity for the IMTC.
It was decided that a discussion on Young Professionals programming should be a standard item on the agenda at each meeting. Additional suggestions and comments from this discussion included:

  • Reach out to professors at local universities.

  • There are difficulties in getting senior leadership to hire people who aren’t necessarily from the top schools.

  • Encourage people to apply for AIST scholarships.

  • Enlist the Young Professionals group to invite past AIST scholarship recipients to events.

  • Share the list of scholarships provided/interns that worked at facilities.

The IMTC reviewed the North American Blast Furnace Roundup. Stuart Street, Roundup chair, went over the data collection process for the coming year.
Additional discussion items included joint meetings with a number of different committees and the possibility of a study tour to India to interact with the Indian Ironmaking Technology Committee.
Technical presentations by producer members focused on casting technologies and casthouse practices. Arcelor­Mittal Cleveland, Stelco, AK Steel – Dearborn Works and ArcelorMittal Dofasco G.P. all presented information. The short presentations facilitated fruitful discussion from the group on casting procedures, tapholes, atypical observations and sampling, to name a few topics. In addition, Arthur Cheng gave a presentation on taphole clay.

The India Member Chapter and the IMTC met 5–6 December 2017, Jamshedpur, India. AS Reddy, Tata Steel Ironmaking Technology Group chief, hosted the group for the seventh meeting of the IMC-IMTC since its inauguration in 2014. 
RN Bhattacharyya, IMC-IMTC chair, opened the meeting and asked for introductions from the 19 attending members. Uttam Singh, Tata Steel vice president — ironmaking designate, and Ashok Kumar, Tata Steel chief technology officer — process, addressed the group and challenged them to provide a forum for blast furnace technology personnel to discuss key technologies, key concerns and key projects. The IMC-IMTC should be a place to share ideas and data for the improvement of the Indian blast furnace community. The IMC-IMTC seeks to meet on a quarterly basis in the future.
The meeting showcased a strong program of technical presentations:

  • Paritosh Haldar, JSPL, presented data and operating experiences with the JSPL Angul 4,554 m3 blast furnace, which has been in operation since May 2017.

  • A Srinivas Rao, JSW, presented JSW’s improved pulverized coal injection (PCI) usage on its blast furnaces and he brought forward to the group a challenge faced with the No. 3 and No. 4 blast furnaces, which have begun to tilt off-center. Much discussion ensued to provide informational assistance to Mr. Rao.

  • Goutam Raut, Tata Steel Ironmaking Process Technology Group, presented on the PCI performance at the Tata Steel Jamshedpur blast furnaces. Tata Steel is seeking to improve the carbon injection rate through an extensive program focused on burden distribution, improved drainage during tapping, and by visualizing the internal state of the blast furnace to understand and make informed decisions.

  • RN Bhattacharyya, RINL – Vizag Steel, discussed the blow-in procedure for Blast Furnace No. 2 at Vizag Steel and its achievement of full production after 20 days.

  • Yogesh Sajjanwar, NMDC, provided an overview of the NMDC blast furnace which will be 4,500 m3 and is expected to be commissioned in September 2018.

  • Sajal Bhattacharjee, Mecon Ltd., provided a perspective on lowering the production costs of Indian blast furnaces. The goal would be to enhance production without CAPEX but also to show improvements in greenhouse gas emissions, zero discharge and improving specific energy consumption. Improving PCI injection, hot blast temperature and oxygen injection are key components to improved production.

  • AS Reddy presented on the Tata Steel Kalinganagar Granshot facility. The facility utilizes excess hot metal to produce shot-sized pellets of pig iron via a tundish pouring the molten iron into an engineered water spray system.

On 6 December 2017, the IMC-IMTC was given a tour of the Tata Steel ironmaking facilities. Included was the casthouse floor of I Blast Furnace, the facility’s newest blast furnace commissioned in 2012 which has a 3,814 m3 working volume, a 13-m-diameter hearth and is capable of producing 8,700 metric tons/day. The attendees also toured the No. 3 Sinter Line, which is capable of producing 350 metric tons of sinter per hour from iron ore fines and plant revert. The final stop was the No. 10 Coke Battery, which was built as part of the 2012 production expansion program at Tata Steel Jamshedpur.
Next IMC-IMTC Meeting: 5–6 April 2018, Hazira, India, hosted by Essar Steel. The committee is also considering a North American Blast Furnace Study Tour for September 2018, which would include a joint meeting with the AIST Ironmaking Technology Committee.
