China’s Shougang Jingtang United Iron & Steel (SGJT) has surpassed 10 mln tons of hot-rolled steel production at its Danieli QSP-DUE (Danieli Universal Endless) casting and rolling line, marking a significant milestone for the ultra-thin strip production technology.
According to Danieli, the plant has demonstrated long-term operational stability, high productivity and consistent product quality since start-up.
A key achievement was the production of more than 420 tons of hot-rolled coils in a single roll campaign at thicknesses of 0.8 mm and below, including 0.7 mm gauges, entirely in endless rolling mode. The result highlights the line’s capability to produce ultra-thin hot-rolled strip on an industrial scale.
The QSP-DUE process combines thin-slab casting, thermal equalization and continuous rolling, enabling stable endless rolling operations, tight dimensional tolerances and high surface quality. The technology also allows operation in endless, semi-endless and coil-to-coil modes within the same production line, providing greater flexibility than conventional thin-slab casting and rolling systems.
Danieli said the performance at SGJT confirms the ability of the QSP-DUE technology to support large-scale production of ultra-thin HRC, helping steelmakers reduce downstream processing requirements, improve material yield and lower energy consumption and CO2 emissions.
Shougang Jingtang United Iron & Steel (SGJT) is a major integrated steel producer located in Caofeidian, Hebei Province, China. The company has an annual crude steel production capacity of approximately 13.7 mln tons and specializes in high-value flat steel products, including advanced automotive steel, galvanized steel, electrical steel and tinplate. SGJT is part of state-owned Shougang Group.
