The AIST Oxygen Steelmaking Technology Committee (OSTC) held their fall meeting on Sept. 17–18 in Baltimore, Md. The technical focus of the meeting was secondary emissions control and MACT standards for BOFs. The members gathered on Sept. 17 for a tour of the BOF steelmaking facility and the continuous caster at Severstal Sparrows Point. A significant portion of the tour was reserved to view the recently installed secondary offgas system at the BOF. Following the tour, the committee gathered for a group reception, dinner and networking event. Many ideas, issues, opportunities and stories were exchanged. On Sept. 18, the committee gathered for a technical discussion and business meeting. As they do at each meeting, the OSTC members exchanged safety incidents of which they were aware, whether at their facility or another facility. The open safety discussion provides immediate benefit to each member, as it gives everyone something to take back to their facility to prevent future injuries or incidents. The committee also discussed the integration of the AIST and AISI oxygen steelmaking committees earlier this year. A subcommittee of producers was formed to evaluate the current BOF benchmarking criteria of the Benchmarking Database. The goal of the subcommittee will be to develop 20–25 specific BOF criteria that will be used to compare BOF facilities across North America and Europe. The committee then began their technical presentations on BOF secondary emissions control. Stu Herman of Severstal Sparrows Point discussed BOF scrubber enhancement and secondary emissions capture. Sam Matson and Eduardo Cordova of Worely-Parsons presented a supplier’s perspective on BOF secondary emissions systems. Mark Presley of Severstal Warren spoke about the 2003 EPA MACT baghouse at the Warren, Ohio, plant. Michael Dauterman of U. S. Steel Gary Works gave a presentation on the steel cycle emissions control at Gary Works. Ron Bannister of ArcelorMittal Dofasco also provided a few notes on the secondary emissions systems at their facility in Hamilton, Ont., Canada. Following the presentations, the OSTC began their business meeting. Mike Strelbisky provided an update on the European Oxygen Steelmaking Conference in Stockholm, Sweden, to be held May 31–June 5, 2009.

January 23-24 , 2008 - The Oxygen Steelmaking Operating Committee (OSOC) met in Westlake, Ohio, on Jan. 23–24 in conjunction with the Energy Industries of Ohio’s Advanced Materials for the 21st Century Steelmaking Technology kickoff event. The entire agenda for Jan. 23 was provided by Energy Industries of Ohio (EIO) regarding a showcase event for their aluminum-bronze research results. Through funding by the Ohio Department of Energy, an innovative material was developed by EIO, Oak Ridge National Laboratories (ORNL) and AmeriFab for the lower hood structure of a BOF vessel. Since the lower hood sees excessive wear from corrosion and erosion during the BOF process, lengthy and untimely outages occur as repairs are made to the typical plain-carbon steel structure (or an inconel-coated equivalant). By developing a new material that reduces repairs to that area, outages are less frequent and energy is conserved as the operation runs more efficiently. Republic Engineered Products (REP) of Lorain, Ohio, trialed the new material, and it has surpassed their expectations in performance. The event began with introductions by Nathan Goebel, division manager of steelmaking at REP, and Robert Purgert, president of EIO, who recognized the dignitaries in attendance. Representation at the event included The U.S. Department of Energy, Ohio State Congresswoman Betty Sutton’s Office, U.S. Congressman Tim Ryan’s Office, as well as suppliers of steel mill–related equipment and technology and individuals involved in the operation of BOF vessels from the United States, Canada, Austria and Germany.
