In order to extend the range of steel grades and increase strip production capacity, Nucor Steel Gallatin contracted with Danieli to upgrade its hot-strip plant in Ghent, in Carroll County, Kentucky, in the United States.
On June 24th the upgraded plant produced the first quality coil. It was an 18-mm-thick strip which is a new product for the plant, obtained thanks to the installation of the new Danieli downcoilers. The new plant configuration – from compact, thin-slab casting and rolling plant into ultra-modern QSP-Quality Strip Production plant – will allow Nucor Steel Gallatin to expand the production of AHSS, API line pipe and a number of other added-value grades, in widths up to 1,870 mm (73.5 in).
Nnew tunnel furnace a.o. upgrades for Nucor Steel Gallatin
The complete production will be delivered by a new, patented, single-strand vertical-curved Dysencaster having a total capacity of up to 3.0 million shtpy. A new tunnel furnace connects the caster to the revamped mill, which now operates in 2+6 mill stand configuration, featuring new roughing stands, advanced combined intensive and laminar cooling, and downcoilers. The revamped plant also includes a new, high-performance DC EAF featuring Q-Melt package and a twin ladle furnace, with future provision for a vacuum degasser. The plant is handled by a complete Danieli Automation process control, from melting to finished hot-rolled coils, ready for Industry 4.0.
This is the first modernization of a classical compact, thin-slab casting and rolling plant, fully reconfigured into an ultra-modern QSP-Quality Strip Production plant.
