In less than 16 months from the date of the contract signing, and ahead of the planned schedule, Steel Dynamics Inc. (SDI) and Danieli Fata Hunter have started up and produced the first coated coil with the new double-coat continuous coil coating line for steel at SDI Columbus, Mississippi facility.
The 600-fpm line will process cold rolled, galvanized, pickled hot band and Galvalume® steel coils with a maximum width of 72” and a maximum base metal thickness of .076”. The line incorporates Danieli Fata Hunter’s patented Single Slide Coating Machines with closed-loop force control including dry paint thickness gauge feedback for the best available control of paint thickness.
The Danieli Fata Hunter Clean AirTM oven system not only will ensure SDI’s customers of superior quality strip, it also will maximize productivity and minimize the operating cost of the line. This oven system, in combination with the Roll-On Pre-Treatment (ROPT) chemical coater and afterburner system, will minimize the environmental impact of the line, meet SDI’s rigorous sustainability criteria and service the market segments that require the most stringent quality standards.
Steel Dynamics Inc., is one of the largest steel producers in the United States with six steel mills, eight steel processing facilities, two iron production facilities, over 90 metals recycling locations and six steel fabrication plants.
