The IMTC discussed nominations for committee officers.
Discussion then focused on issues with getting producers involved in the committee and the importance of the membership chair for helping to keep producers involved.
The Blast Furnace Roundup was reviewed, which is published in the March issue of Iron & Steel Technology.
Stuart Street discussed the AIST Process Benchmarker® and gave an update on the IMTC’s Rule of Thumb.
The committee discussed the importance of its November meeting and whether it is still needed, since its original purpose was to put together the paper sessions for AISTech. Today the deadline for assembling the session layouts is months before the November meeting and everything is completed by the papers chair before that meeting. The possibility was discussed of having a webinar for this meeting instead to go over the session layouts for the rest of the committee to see.
Scholarships from the AIST Foundation were brought up for discussion, and members were reminded to encourage students to apply at

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.

While the revisions to the questionnaire are developed, a user’s guide for filling out the questionnaire will also be developed by Sadri. The goal is to publish the DRI Roundup with the EAF Roundup in  the January 2016 issue of Iron & Steel Technology. Therefore, the roundup shall be submitted for publication by 1 November 2015.
The next DRI Seminar was discussed. The DRISC would like to host the Scrap Substitutes and Alternative Ironmaking symposium in the fall of 2016.
Discussion was held regarding how to make the DRISC a stand-alone Technology Committee. Mark Rosi of AIST said this process has already started but will be decided by the AIST Board of Directors. The subcommittee was encouraged to keep up with the work it has already started to demonstrate the viability and need to become an independent Technology Committee.
