Exceeding performances: SGJT rolls hot-rolled strip down to 0.7 mm

Chinese steelmaking pioneer Shougang Jingtang United I&S –first in operating a hot-rolled coil plant capable of performing in three operational modes for maximum production flexibility– carried out a successful trial production of 0.7 mm ultra-thin specifications at its QSP-DUE plant in the Caofedian industrial area, Tangshan city, Hebei province, China.

The plant, featuring Danieli Universal Endless -DUE technology, can roll various steel grades including weathering steel, peritectic, alloy steels, TRIP, and Dual Phase, with widths ranging from 900 to 1,600 mm and thicknesses from 0.8 to 12.7 mm, surpassing design expectations.

Starring the Danieli-patented DySen caster, the Shougang Jingtang QSP-DUE plant has achieved a casting speed of 6.0 m/min and a sequence length of 29 heats over an uninterrupted casting period of 16.7 hours. The plant’s monthly productivity is in the proximity of 200,000 tons.

By maximizing the production of light and ultralight gauges –60% below 1.5 mm– the Danieli Universal Endless plant provides Shougang Jingtang with a competitive advantage in the challenging Chinese market.
