Linde and ArcelorMittal will describe the benefits of using flameless oxyfuel technology in a continuous steel reheat furnace at AISTech 2008, the premier steel industry technology event in North America.
The Linde Group is a leading global gases and engineering company. ArcelorMittal is the world's largest and most global steel company. Mike Lantz and Doug Hassenzahl of ArcelorMittal will present a paper on how the Linde REBOX® flameless oxyfuel solutions increased reheating throughput and reduced fuel consumption at ArcelorMittal Shelby – Tubular Products in Shelby, Ohio. The paper was co-authored with Anders Lugnet, Grzegorz Moroz and Anders Carlsson of Linde.
AISTech 2008 begins May 5 at the David L. Lawrence Convention Center in Pittsburgh. The Linde REBOX technologies will also be featured in booth #1552.
In their presentation on May 7, the authors will describe how, in 2007, Linde North America led a four-month, turnkey project to implement the REBOX® flameless oxyfuel technology at the seamless tube mill. The result was a 25 percent increase in reheating capacity and a decrease in fuel consumption of 50 percent versus oxy-enrichment and 65 percent versus airfuel. The implementation also delivered improved temperature uniformity for better piercing results, a 50 percent reduction of scale formation and minimized nitrogen oxide (NOX) and carbon dioxide (CO2) emissions.
Tony Palermo, metals market segment manager, Linde North America, said, "Linde’s portfolio of unique REBOX® oxyfuel solutions gives the steel industry a range of options for improving productivity and operating flexibility, reducing costs and cutting greenhouse gas emissions on reheating and annealing furnaces, often as turnkey projects with guaranteed performance. The REBOX solutions have been very successful in improving the performance of existing equipment without a large capital investment.”
Linde’s in-house furnace and process engineering experts have converted over 110 furnaces worldwide to REBOX oxyfuel combustion. REBOX oxyfuel solutions enable rolling mills, forge shops, annealing operations and hot-dip galvanizing lines to increase furnace throughput by as much as 50 percent and improve operational flexibility, heating performance and temperature uniformity while reducing scale formation and cutting fuel consumption.
