SSAB and Danieli have signed an Early Service Agreement (ESA) for the pre-engineering phase of the Lulea mini-mill project in Sweden. Danieli will provide a highly automated mini-mill solution featuring two electric arc furnaces, secondary metallurgy, a caster, and a strip mill, marking a significant step in SSAB’s decarbonization efforts.
The new mill will have an annual capacity of 2.5 mln tons and will utilize fossil-free sponge iron from the Hybrit demonstration plant alongside recycled scrap. It will include advanced secondary metallurgy, a direct strip rolling mill for specialty products, and a cold rolling complex for the mobility segment.
Danieli’s design incorporates two DigiMelters with advanced features for efficient melting and reduced emissions, along with twin-ladle refining stations and vacuum degassers. The QSP-DUE technology will enable SSAB to produce a wide range of hot-rolled strips while maintaining a minimal carbon footprint through a fully electric tunnel furnace.
Startup is planned for late 2028, with full capacity expected by 2029. Environmental permits are anticipated by the end of 2024. This investment is crucial for SSAB’s strategy to lead in emission-free special and premium steels, ultimately reducing Sweden’s CO2 emissions by 7pct.
