Pittini Group’s new Acciaierie di Verona high- speed wire rod mill has produced its first coil, just 19 months after contract signing. The start-up and seven-week hot-test period, during which 25,000 tons of finished wire rod were produced, reflects the long-term cooperation between Pittini Group and Danieli, who supplied the advanced wire rod technologies and Danieli Automation Q3 intelligence system. Equipped in full compliance with Industry 4.0 requirements, the plant will produce 750,000 tonnes per year of plain wire rod from 5.5mm to 25mm, and rebar from 6mm to 18mm, at a rolling speed of 100m per second. The mill is characterized by a high-speed rougher feeding two independent rolling lines of cantilever roll stands, with quick roll changes and temperature control along the mill and downstream. High-speed shears, installed downstream of the multi-drive twin- module sizing blocks, perform wire rod head and tail cropping. The fourth-generation loop layers are said to guarantee extended pipe life, quick rotor changes, and no vibration during rolling, resulting in perfect loops from heads to tails. The variable-pitch cooling conveyor features modular slow-to-ultrafast cooling. Strict end-product size tolerances have been achieved from the start.
