Severstal North America, a flat-rolled steel producer headquartered in Dearborn, Mich., has been recognized as the Gold Medal winner in the Reliability Achievement Award by the Association for Iron and Steel Technology (AIST). The award, open to all North American iron and steel producers, recognizes an individual project that has had significant impact on the plant's operational reliability.
Severstal North America says its Dearborn ironmaking team focused on improving blast furnace tuyere life. Industry-wide, a tuyere failure is accompanied by furnace instability, increased costs, lost productivity and increased safety and environmental risks. A tuyere is a device that allows heated, oxygen-enriched air to be blown into the combustion raceway of a blast furnace during the steelmaking process.
