Systems Spray-Cooled Recently Completes BRS Phase II Melt Shop Expansion
May 2021 Nashville, TN – As part of its Phase Two expansion that was recently completed, Big River Steel in Osceola, Arkansas installed and commissioned new Spray-Cooled™ on furnace electric arc furnace (EAF) equipment including a roof, elbow, sidewall, and off-gas duct work with Systems Spray-Cooled from The Systems Group.
The EAF roof is a gantry-style roof with a steep cone hot face profile for optimization and extended lifetime. The elbow incorporates a new integrated drain design that eliminates bolted connections for quicker change-outs. The EAF sidewall incorporates a unique proprietary hot face profile that includes integrated ‘bump-outs’ to help protect the burners and refractory bricks and reduce scrap jams at the slag door opening area.
As part of the project, Systems Spray-Cooled partnered with SMS Group to provide a complete Spray-Cooled™ Direct Evacuation Control System (DECS) consisting of a D1 downcomer duct, Drop-out Chamber (DOC), and downstream duct for all the water-cooled equipment. The D1 downcomer duct is hydraulically actuated on a fixed rail support system allowing real-time air gap adjustment. The DOC is a panelized, self-supported design consisting of 20 sidewall and roof panel segments, a hydraulically actuated access door for cleanout, and a manually actuated emergency exit access man door. The downstream duct includes an electric-driven actuator, and 12 sections of duct work (D2 through D13) totaling 236 feet in length and including a support structure tower with access platforms and ladders for the vertical duct section. Big River Steel expects the spray-cooled duct work will cool the off-gas more efficiently than typical tubular ductwork. In all, 33 pieces of spray-cooled equipment were installed and commissioned at Big River Steel for the Phase Two expansion.
Big River Steel’s decision to install Spray-Cooled™ equipment was based on the need for the safest, most reliable solution when considering long-term maintenance costs.
