The state-of-the-art rolling mill known as “Walzwerk B” sets a new benchmark in the European steel industry in terms of both production efficiency and decarbonization targets.
The new facility replaces traditional gas-fired heating systems with induction heating technology, which enables zero direct CO₂ emissions. Connected directly to the existing continuous casting line via a 300-meter-long hot charging roller table, this setup marks a significant step forward in energy savings and environmental sustainability.
ESF implements endless rolling using Danieli’s K-Welder technology. This sixth-generation welding machine efficiently joins billets end-to-end, reducing maintenance times by 50%, increasing productivity, and lowering operating costs.
The new rolling mill comprises 16 housingless stands, a six-pass multi-drive finishing block, and a roller conveyor line. Another standout feature of the facility is the K-Spooler system, which produces twist-free spooled coils of deformed bars ranging from 8 to 25 mm in diameter and weighing between 2.5 and 8 tons. The eight-ton coils produced are the heaviest rebar spooled coils in the world.
Danieli’s Multi-Stage Soft Quenching (SQ2) technology delivers more uniform and superior metallurgical properties while optimizing the thermomechanical process compared to conventional loop systems. Meanwhile, Danieli Automation’s big data and artificial intelligence solutions create real-time connectivity between the casting and rolling lines, reducing energy consumption and enhancing final product quality.
To mark the opening of the new facility, ESF hosted a roundtable attended by ministers from Germany and Italy, steel associations, and leading European steel producers. The event provided an in-depth discussion on the European steel industry’s vision for digitalization, green transformation, and sustainable production.
