Marcegaglia and Danieli have signed an agreement to begin the engineering phase of the Mistral Project, a flat-product minimill in Fos-sur-Mer, France.
Danieli will supply a fully automated plant covering scrap preparation, electric steelmaking, slab casting, and hot-strip rolling. The minimill will produce up to 2.1 mln tons per year of stainless and carbon steel hot-rolled coils, meeting about 30pct of Marcegaglia’s HRC demand and supplying its Ravenna cold-rolling complex.
Key equipment includes a Fastarc Zerobucket furnace with continuous scrap charging and preheating, Q-Melt adaptive process controls, twin-ladle refining, and vacuum degassing units, designed for energy efficiency and lower emissions. A single-stand caster will produce slabs for both the new hot-strip mill and Marcegaglia’s plate mill in San Giorgio di Nogaro, Italy.
The flexible mill layout combines a Steckel mill and five-stand finishing mill, enabling stainless slab rolling from Marcegaglia Sheffield and continuous carbon-steel rolling from the caster. Danieli will also provide advanced water and fume treatment systems.
Backed by Danieli Automation controls, the minimill is scheduled to start production by mid-2028.
