23.06.2021. Optimus Steel Inc. has selected Danieli to modernise the complete rolling process for its 1 Mt/a minimill producing special steel wirerod in Vidor, Texas, USA. Full rolling mill modernisation is expected to be completed by the end of 2021.
Two HSS High-Speed Shears for automatic cropping will be installed after the wirerod blocks on each of the two rolling strands to perform consistently at finishing speeds up to 115 m/s. Two Danieli oil-film bearing laying heads equipped with patented, double-pipe rotor technology will guarantee 5–6 times longer pipe life compared to conventional solutions.
A new coil-finishing area will include the Sund Birsta technology, in which all coils are processed first along the vertical trestle line and then through a C-hook conveyor equipped with a trimming station, horizontal compactor and unloading system.
Other improvements will be made to upgrade the minimill’s water treatment plant and to supply a new one to guarantee higher environmental standards and comply with local requirements.
A complete electrical and automation package for all technology will be delivered by Danieli Automation.
Demanding requirements of the USA market
This technological update, the result of a partnership and a shared vision between Optimus Steel and Danieli to achieve superior results and business growth, will significantly increase OS production, product quality and safety conditions inside the plant while reducing operating expenses, thus meeting the demanding requirements of the USA market.
