SSAB and Danieli Finalize Technology Deal for Low-Carbon Mini-Mill in Luleå

SSAB and Danieli Finalize Technology Deal for Low-Carbon Mini-Mill in Luleå

(IN BRIEF) SSAB has finalized a contract with Danieli to deliver a fully automated production solution for its planned 2.5 Mt/year mini-mill in Luleå, Sweden. The facility will feature two electric arc furnaces, advanced refining and vacuum degassing systems, and direct strip and cold rolling capabilities to serve specialty and mobility markets. With energy-efficient technologies like continuous scrap charging and thermal recovery, the mini-mill will significantly lower emissions. Once complete, it will replace the existing blast furnace operations, helping cut Sweden’s CO2 emissions by 7%. The investment reflects SSAB’s goal of becoming a leader in decarbonized steel production.

(PRESS RELEASE) STOCKHOLM, 10-Jun-2025 — /EuropaWire/ — SSAB has taken a significant step in its decarbonization journey by signing a major technology supply contract with Danieli for its upcoming mini-mill in Luleå, Sweden. Building upon the Early Service Agreement signed in July 2024, the new agreement outlines Danieli’s delivery of a comprehensive, highly automated steel production solution, including two electric arc furnaces (EAFs), secondary metallurgy systems, a continuous caster, and a direct strip rolling mill.

Designed with a production capacity of 2.5 million tonnes annually, the new Luleå mini-mill will be equipped to manufacture hot-rolled strip in a range of thicknesses from 1.3 mm to 25.4 mm, widths up to 2100 mm, and coil weights up to 40 tonnes. The facility will include a cold rolling complex aimed at serving the mobility sector with high-quality premium steel products.

At the core of the meltshop will be two 210-ton Digimelters, each outfitted with Danieli’s Q-One power feeder system that enables thermal energy recovery for district heating. Additional innovations include ECS continuous scrap charging for energy-efficient operations and the MeltModel suite for real-time melting control. The mini-mill will further enhance steel quality through twin-ladle refining and twin-tank vacuum degassing stations.

The facility’s use of endless scrap charging is expected to boost furnace efficiency and significantly reduce NOx emissions. Once operational, this mini-mill will replace SSAB’s existing blast furnace-based setup in Luleå, contributing to a 7% reduction in Sweden’s overall CO2 emissions. Coupled with the ongoing transformation of SSAB’s Oxelösund mill, the combined impact will cut national emissions by 10%.

This investment is central to SSAB’s ambition to lead the global shift toward fossil-free and premium steel production, reinforcing its commitment to climate responsibility and technological innovation.

SSAB is a Nordic and US-based steel company that builds a stronger, lighter and more sustainable world through value added steel products and services.
