There are currently 61 members of the CMTC, with five new members since the previous meeting. A safety round table discussion began with a review of the Safety & Health Technology Committee’s 2009 Steel Industry Fatalities Report and current statistics. Two other graphs depicted a three-year period of steel industry fatalities by type and by reason since 2006. These graphs helped generate a dialogue regarding safety issues experienced at various plants and the corrective action taken to improve performance. The 2009 Coke Battery Roundup appeared in the January issue of Iron & Steel Technology. This roundup will be reviewed/revised each year with the hope of expanding coverage to recognize all the cokemaking facilities in North America. The CMTC recognized Toni Brayton, U. S. Steel–Gary Works, for her efforts in organizing this initial Coke Battery Roundup.

Election of CMTC officers provided the nominations and approvals for the following: Brad Parker, chair; Rob Carlin, vice chair; Toni Brayton, papers chair; Tim Wojtowicz, membership chair; Ted Todoschuk, Becker Award nominating chair; and Frank Jere, AIST BOD representative (two-year term). The CMTC mission statement was reviewed and approved. The Cokemaking Benchmarking Subcommittee chair, Rob Carlin, conducted a conference call Wednesday, 10 Jun, so the CMTC could update a list of current cokemaking facilities. The AISTech 2010 Call for Papers asks each CMTC member to solicit papers for next year’s conference. A suggestion was made to reach out to European cokemaking counterparts to participate in AISTech 2010. The next CMTC meeting is scheduled for 8–10 Sep 2009, with a plant tour of DTE Energy Services with host Rob Carlin. Contact Brad Parker before 1 Aug 2009, if you’d like to make a 30-minute PowerPoint presentation on one of the following topics: safety and health with cokemaking; environmental issues; biological treatment facilities; idling and start-up concerns; recovery strategies — new technologies; and reduced capacity operations.

The Cokemaking Technology Committee (CMTC) met in Coraopolis, Pa., in conjunction with the Eastern States Blast Furnace and Coke Oven Association on 5–6 Feb. CMTC meeting attendance was 23 members, with two new members: Lauren Keating and Paul Todaro from U. S. Steel. The current CMTC roster stands at 93 members. Safety round table discussions included plant statistics, eye safety, project landscape changes during construction, gas safety issues and alarm equipment measuring levels, PPE apparel color change to orange for easier recognition, and continued efforts to motivate employees to adopt the safety programs. The CMTC recognized AK Steel–Middletown for having zero recordable injuries for 2008. Production concerns highlighted mercury discharges at a bio plant, and implementing activated carbon technology to control Hg discharge. Energy savings continue to have a strong, plant-wide focus. The CMTC was reminded to use the group e-mail address, cmtc@aistnetwork.org, whenever an accident occurs at their facility, so that available details can be communicated as soon as possible to the committee in hopes of preventing a similar accident from occurring at another plant.
AISTech 2009 awards were discussed. The Josef S. Kapitan Award will be given to Sushil Gupta, University of New South Wales, for his paper, “Effect of Coke Mineral and Carbon Structure on Coke Behavior in the Ruukki Blast Furnace.” The Becker Award subcommittee will finalize their selection by 1 Mar 2009. The Becker Award Subommittee chair, Ted Todoschuk, will inform the CMTC of this year’s recipient. Guidelines for the Becker Award will be reviewed by the Subcommittee after AISTech 2009. There is a strong consensus that a cokemaking benchmarking database is desirable, as long as it is easy to use and the information gathered is useful. CMTC members were encouraged to submit comments/suggestions to Rob Carlin, Benchmarking Subcommittee chair. Toni Brayton, Tim Wojtowicz, Danielle Anderson, Brad Parker, Paul Todaro, Rick Lyons and Lauren Keating comprise the Benchmarking Subcommittee. Joel Sundholm will provide benchmarking variables used in the AISE Coke Producing Committee format. Identifying key variable statistics to benchmark will be a top priority. The benchmarking database will be restricted to coke producing members and only those members who submit data. CMTC officer nominations for 2009–2010 were discussed. Brad Parker was nominated as chair, Rob Carlin as vice chair, and Toni Brayton and Tim Wojtowicz as papers chair. These nominations will be confirmed at AISTech 2009 during the next CMTC meeting on Tuesday, 5 May.
