US steel maker Nucor Corporation has entrusted Danieli and its innovative technologies for equipment and automation with new orders valued in excess of USD 650 million, representing the largest worldwide order for equipment and automation in the last 20 years. Nucor selected QSP-DUE Danieli Universal Direct Rolling technology for a new Greenfield installation in West Virginia to produce quality hot strip, and cold-strip rolling and processing technology for two cold-strip projects. The startup of these plants will begin in mid-2024, with operation by the end of 2024.The QSP-DUE Danieli Universal Endless plant will produce 3.0 million short ton per year of quality hot-rolled strip in the widest range of steel grades and most flexible way; strip dimensions up to 2,100 mm wide and from 0.8 to 25.4 mm thick. Danieli QSP-DUE is the only technology that allows coil-to-coil, semi-endless and endless modes to be performed in a single line. This will be the first thin-slab casting rolling plant to produce also automotive-exposed grades, allowing Nucor to operate without steel grade limitations. The plant will be managed by Danieli Automation’s advanced process technologies and artificial intelligence. Q3 pulpits will support Nucor Steel operators in supervising fully automated plants, making use of big-data analysis and Q3 manufacturing execution systems. Robotized solutions will increase plant safety according to zero-men on the floor concept.First, a new Pickling Line and Tandem Cold Mill -PLTCM and temper mill to complete the QSP-DUE quality hot-strip plant will process 2.3 M million short ton per year hot-rolled strip, 0.80 to 6.35-mm-thick, up to 1,982-mm-wide, into 0.25 to 3.05-mm-thick cold-rolled strip for both construction and automotive products. The pickling line will be characterized by patented Turboflo technology for highly efficient scale removal and high- and adjustable-turbulence on both strip surfaces at speeds up to 250 meters per minute.Coupled with the pickling line, a five-stand tandem cold-mill mill featuring Danieli original 6-hi Optimized Shaped Roll Technology will ensure the best strip flatness, thickness control and performance stability at speeds up to 1,200 meters per minute.A 0.45 million short ton per year stand-alone temper mill to improve material formability, flatness and surface finish grades in dry and wet tempering modes will complete the Danieli supply for this new cold-mill complex.A second order for cold-strip technology is for a galvanizing line and a color-coating line to be installed at the existing Nucor Steel Crawfordsville plant, Indiana, to serve markets for steel buildings and home appliances.Danieli Automation will provide advanced process control systems to supervise operations, running the lines in automatic mode, guaranteeing quality and production consistency.
