Yuxi in Yunnan Province based private Chinese steelmaker Yukun I&S has selected Danieli casting and rolling technology for the relocation project to Eshan County. The Danieli supply will consist of the technological equipment for four, 7-strand high-speed casting machines with 28 casting strands and seven rolling mills arranged in three nearby bays, totaling 167 rolling mill stands, including spares. All these new casters will produce 165-mm quality billets with liquid steel supplied by Yukun ironmaking plants, and provide the new rolling mills with hot billets for hot-charge practice. This will minimize reheating energy consumption and rolling power absorption, resulting in up to 12% OpEx savings. Each of the new Yukun mills will make use of horizontal and vertical SHS stands. Plant start-up is expected by 2023. The first caster will feed three wirerod lines with the capacity to produce 0.8 Mtpy of deformed and plain rounds (5.5-16-mm-dia) per line. These mills will feature 6-pass pre-finishing blocks and 4-pass multi-drive finishing blocks, and laying heads equipped with oil-film bearing rotors to reduce vibration and noise, ensuring improved wirerod patterns and pipe lifetime. Rolling speed 110 m/sec.The second and third casters will deliver billets to the two bar lines capable to produce up to 2.3 Mpty of rebar (18-40-mm-dia) each line. A multi-strand slit-rolling system will be deployed for diameters up to 28 mm; and a single-strand solution will handle the remaining measures. Each line will include two 2-pass finishing blocks.The fourth caster will serve two HTC high-speed bar lines to produce 12-to-20-mm-dia. rebar. One rolling mill will produce 1.7 Mtpy in a multi-strand slit-rolling configuration, whilst a second rolling mill will produce 1 Mtpy of rebar in single line configuration.Both lines will operate 4-pass pre-finishing blocks and two 2-pass multi-drive finishing blocks.All the Yukun mills will deliver Danieli UFG (Ultra-Fine Grain)-processed products, ideal for reliable construction applications.
