135.4 m/s: Danieli wirerod mills break rolling speed records
Operating Danieli fast-finishing blocks and loop layers, ABS and Ferriere Nord wirerod mills set new records in two weeks
On 17 September, Italian special steel maker ABS set a new rolling mill speed record of 132.4 m/s, equal to 476,64 km/h rolling 5.5-mm-dia wirerod.
This record was reached on the new, “QWR 4.0” special steel wirerod mill in Cargnacco, Italy, where 500,000 tpy of wirerod 5.0 to 25 mm dia for automotive applications are produced. There, high quality and tolerances of ±0.1-mm dia are achieved thanks to the four-pass Twin-Module Block -TMB sizing mill.
Controlled by the most advanced automation and control systems, QWR 4.0 mill can perform several kinds of heat treatments which grant ABS a wide operational flexibility.
Two weeks later, Italian long products producer Pittini Group achieved the speed of 135.4 m/s (487.44 km/h) setting the new world speed record.
This occurred at Ferriere Nord minimill –supplied by Danieli– which competitively produces wirerod, straight bars and spooled coils in low-carbon steel for construction purposes.
The Ferriere Nord two-strand wirerod mill features a three-pass Compact Sizing Block -CSB, which has been in operation since 2015.
Both mills are equipped with Danieli high-speed shears and oil-film bearing laying heads, which together with the sizing mills allow them to reach such high speed (high productivities) and low-dimensional tolerances.
