Chinese steelmaker Yukun Iron and Steel Group has successfully produced 145-mm-thick slabs at its new Danieli QSP-DUE plant in Yuxi, Yunnan province, setting a record for direct casting and rolling facilities.
This achievement was made possible using a 152-mm funnel mold, reaffirming the Danieli-patented DySen caster as a benchmark in slab-casting technology. The increased slab thickness enhances overall strip quality by improving the reduction ratio in the mill and expands the potential of the QSP-DUE process for high-quality hot-rolled coil production.
Yukun’s Danieli QSP-DUE plant is designed to produce low- and medium-carbon, HSLA, and medium-carbon high-alloyed grades. It can manufacture ultra-light gauges as thin as 0.8 mm in endless mode and thick gauges up to 25.4 mm in coil-to-coil mode. With two casting strands, one dedicated to endless casting and rolling, the plant has an annual production capacity exceeding 4.5 mln tons of hot-rolled strip, making it the most advanced direct casting-rolling facility in the world.
