Marcegaglia and Danieli have signed an agreement to begin the engineering phase of a flat-product minimill project.
The partnership, named the Mistral Project, is located in Fos-sur-Mer, France.
Through the collaboration Danieli will deliver a fully automated minimill that will include production equipment for scrap preparation, electric steelmaking, slab casting and hot-strip rolling.
The new minimill will produce up to 2.1 Mtpy of stainless and carbon steel hot-rolled coils to supply the Marcegaglia cold-rolling complex in Ravenna, Italy, covering around 30% of overall company HRC demand.
The Danieli special mill design will permit Marcegaglia ultra-flexible production due to an integrated Steckel mill and hot-strip mill setup within a single configuration.
The design consists of a roughing stand and a five-stand finishing mill, with the first stand adaptable for Steckel operation.
This will enable the rolling of stainless-steel slabs from Marcegaglia Sheffield plant in Steckel mode, and of carbon-steel slabs from the caster in continuous mode through the five-stand finishing mill.
Additionally for electric steelmaking, the melt shop will feature a Danieli Fastarc Zerobucket furnace equipped with ECS continuous scrap charging and Tornado preheating system, and Q-Melt adaptive process control with auto-pilot.
Liquid steel will be processed into quality grades by twin-ladle refining stations and twin-tank vacuum degassers, ensuring high energy efficiency and reduced carbon and NOx emissions.
The single-stand caster will produce 200 to 250-mm-thick carbon steel slabs, partly feeding the new hot-strip mill and partly supplying the Marcegaglia plate mill in San Giorgio di Nogaro, Italy.
To ensure environmental compliance, Danieli advanced water-and fume-treatment systems will also be supplied.
The minimill is expected to start production by mid-2028.
The investment reinforces Marcegaglia’s commitment to strengthening its competitive position in the European hot-rolled coil market.
