Marcegaglia selects Danieli for new hot-rolled coil minimill project in Fos-sur-Mer

Marcegaglia and Danieli signed an agreement to initiate the engineering phase of the flat-product minimill project in Fos-sur-Mer, France.

Under this agreement, Danieli will deliver a cutting-edge, fully automated minimill that will include all the production equipment for scrap preparation, electric steelmaking, slab casting, and hot-strip rolling.

Named as Mistral Project, 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, covering around 30% of overall company HRC demand.

The new electric steel meltshop 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.

The Danieli special mill design will permit Marcegaglia ultra-flexible production, thanks to an integrated Steckel mill and hot-strip mill setup within a single configuration. It consists of a roughing stand and a five-stand finishing mill, with the first stand adaptable for Steckel operation. Such arrangement 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.

Danieli advanced water- and fume-treatment systems, ensuring full environmental compliance, will also be supplied.

Supported by Danieli Automation process control systems, the minimill is expected to start production by mid 2028.

The investment reinforces Marcegaglia’s strategic commitment to strengthening its competitive position in the European hot-rolled coil market through sustainable, high-efficiency production.
