This steel making plant was originally part of the Ford Motor Company, which created an integrated manufacturing complex to produce all major vehicle components at one large facility called The Rouge. In 1989, Ford’s steel assets were divested and became known as Rouge Industries with the steel operations trading as Rouge Steel Company in Dearborn, Mich., outside of Detroit.

Today, Severstal Dearborn, a fully integrated plant located close to its consuming markets, remains a critical and valued supplier to the automotive industry while expanding to serve other markets as well. Recent major capital expenditures include a new, state-of-the-art blast furnace that began operation in 2007. In the near future, Severstal Dearborn will complete the construction of a continuous linked pickle tandem cold mill and a hot-dip galvanizing line.

Products

Severstal Dearborn produces high quality flat-rolled products, including hot rolled band and hot rolled processed sheet, cold rolled sheet, hot dipped galvanized sheet, electro galvanized sheet, and aluminum coated boron and other advanced steels.

Hot Rolled Products

Severstal Dearborn’s 68 in. hot strip mill has an annual throughput of 3.8 million tons (3.5 million metric tons). The hot strip mill can roll to a minimum gauge of .050 in. through .525 in. (1.27 mm through 13.30 mm) in widths from 30 in. to 61 in. (762 mm to 1,549 mm). The recently modernized slab reheat furnaces optimize Severstal Dearborn’s heating efficiency and quality, reduce natural gas consumption and increase yield.

Cold Rolled Products

The Severstal Dearborn's cold mill produces 1.8 million tons (1.6 million metric tons) of steel in thicknesses from 0.014 in. through 0.110 in. (0.36 mm through 2.79 mm) with widths form 28 in. to 61 in. (711 mm to 1,549 mm). A cornerstone of Severstal Dearborn’s modernization will be the most sophisticated pickle tandem cold mill (PLTCM) in the world. The PLTCM will roll to a minimum gauge of 0.012 in. (0.30 mm) and final width of up to 72 in. (1,850 mm) with product flatness requirements of less than 15 I-units.

Coated Products

Severstal Dearborn’s coating capabilities include one of the largest electrogalvanizing lines and state-of-the-art hot-dipped galvanizing capabilities. Also part of the Dearborn modernization will be a new hot dipped galvanizing Line which will include state-of-the-art controls for coating thickness and surface texture as well as alloy and phase control. The line will be capable of producing 496,000 tons (450,000 metric tons) of best-in-class exposed hot dipped galvanized (HDGI) and exposed hot dipped galvanneal (HDGA) steel. These capabilities are, and will be used to produce demanding steels such as high-end automotive products, dual-phase, TRIP (Transformation-Induced Plasticity) and high reduction interstitial-free steels for customers in the automotive, appliance, and furniture industries.
