In 1982, SSAB, Luleå Works, converted the blast furnace ferrous burden from an acid to an olivine pellet with a high Fe content. This change made it possible to gradually reduce the slag volume

SSAB’s blast furnace in Luleå, Sweden is now turning out premium quality crude iron after undergoing full modernization lasting more than three months. The blast furnaces in Raahe, Finland were modernized as recently as 2011 and an investment in a pulverized coal injection system has now been completed there. This investment will reduce annual costs by around SEK 200 million from 2016 onwards.

Remote control of locomotives enables total control of 300 tons of molten steel in 2000, SSAB invested in a state-of-the-art blast furnace for the Luleå operation. Flue dust becomes blast furnace fuel. By recirculating flue dust as fuel in the blast furnace, both raw-material costs and environmental impact can be reduced. The method is now used at SSAB in Oxelösund. The idea of using blast furnace dust and sludge as a fuel supplement in the blast furnace was conceived as early as the late 1990s. ** SSAB Tunnplåt AB, SE-971 88, Luleå, Sweden *** Luleå Tekniska Universitet, SE-971 87, Luleå, Sweden Key words: CO2-emissions, steelmaking, ironmaking, blast furnace, energy efficiency, alternative iron- and steelmaking ABSTRACT Possibilities to reduce the CO2-emissions from SSAB Tunnplåt AB’s ore based steel production in Continuous progress of the blast furnace (BF) process for almost 200 years Step change in 1980’s −LKAB development of iron ore pellets −SSAB development of BF-process: •Shut down sinter plants in Luleå, Oxelösund & Raahe Source: SSAB and Stahl-Zentrum.

31 August, 2017. Use of biocarbon in blast furnace-based steelmaking could reduce carbon dioxide emissions by as much as 30 percent in the short to medium term. In a recently started research project under the direction of Swerea MEFOS the methods will be developed and tested at SSAB. Lowering the carbon consumption and fossil CO2 emissions is a priority in blast furnace (BF) ironmaking. Renewable biomass is one option that can play an important role in future low-carbon ironmaking particularly in the countries rich in biomass resources.
