U.S.-based Primetals Technologies reports that it has received a Final Acceptance Certificate (FAC) from Celsa France for a major upgrade to the finishing end of the company’s wire rod mill in Bayonne, France.
A Primetals posting said that the company replaced a problematic finishing block and reform station “that had been supplied by a third party and had repeatedly caused unplanned downtime.” With the new equipment in place, Celsa France has significantly increased mill availability and production levels while improving product quality and reducing operational costs.
The upgrade included a new 10‑stand Morgan Vee No‑Twist Mill designed to operate at speeds up to 105 meters per second across low‑, medium‑, and high‑carbon steel grades. The installation also included a 3‑Hi speed increaser gearbox that links the new mill to Celsa France’s existing motor position, demonstrating the design flexibility and compatibility of the technology. The upgrade has already led to quicker, more efficient rolling, reduced maintenance costs, and shorter roll change times.
The project also saw the replacement of the 1,200 mm reform tub. Equipped with a patented ring distributor, the new tub minimizes coil height, eliminates stray rings, and ensures tangle‑free payoff. These improvements have dramatically reduced delays in downstream processing, further enhancing overall productivity.
Celsa France was described as Europe’s first circular, low‑emission steel producer, recycling ferrous scrap in electric arc furnaces to produce steel for construction, automotive, energy, and oil and gas sectors. The Bayonne upgrade strengthens this position by ensuring that the company’s wire rod production is both efficient and environmentally responsible.
According to Celsa France, the Bayonne facility produces about 550,000 tons of rolled products annually, primarily wire rod. The recent upgrade adds to an earlier €65‑million investment that created around 140 direct and 420 indirect jobs across France and Spain.
