SSAB’s (Svenskt Stål AB) Luleå steel plant, situated in northern Sweden, is a cornerstone of the region’s industrial landscape. Established in 1940, it has evolved into a comprehensive facility encompassing various stages of steel production. The plant’s operations include coke making, where coal is processed into coke; iron making, primarily conducted in the blast furnace; steelmaking, involving the conversion of pig iron into steel; and continuous casting, where molten steel is solidified into slabs. These slabs are subsequently rolled into finished products, catering to diverse industrial applications.

Central to the plant’s ironmaking process is Blast Furnace No. 3. This furnace has undergone significant upgrades to enhance its efficiency and longevity. Notably, in 2015, a major reline and modernization project was executed, which included the installation of advanced copper stave cooling systems and other technological enhancements. This refurbishment aimed to improve the furnace’s performance and ensure its operational reliability for the ensuing campaign. 

In line with global sustainability trends, SSAB has embarked on a transformative journey towards fossil-free steel production. A pivotal aspect of this initiative is the planned transition from traditional blast furnace methods to electric arc furnace (EAF) technology. The forthcoming mini-mill in Luleå will feature two EAFs, advanced secondary metallurgy, a direct strip rolling mill, and a cold rolling complex. This transition is expected to reduce Sweden’s CO₂ emissions by 7%, marking a significant stride towards sustainable steel manufacturing.
