This paper presents the development and commercialization of a novel dust extraction technology. Driven by stringent EU emission regulations, the need for more efficient dust removal solutions has become paramount in industries like mining and metallurgy. By combining fundamental fluid dynamics research with industrial practice, SSAB researchers and Oulu University developed a modular dust...
The steel industry is a cornerstone of the European economy, contributing 6.7% of global crude steel production (126.3 Mt in 2023). However, it is also a major source of greenhouse gas emissions, accounting for 4% of total EU emissions and 23% of those from manufacturing industries. Achieving carbon neutrality in this high-energy-intensity sector requires innovative solutions to reduce...
The increasing need for steel has rised the consumption of metcoke where in Europe 45 million tons of metcoke are used annually in steelmaking processes. In the attempt for green transition, this growing need is accelerating the search for sustainable alternatives to fossil carbon products.
Pyrolysis of wood pellets from pine and spruce at temperatures above 500°C has proven effective in...
Improving the circularity of steel products requires reliable tools for ECO design that integrate key environmental properties, such as CO₂ footprint and embodied energy. These data are typically de-rived from environmental reporting and Life Cycle Assessment (LCA) analyses. However, ensuring physically consistent and traceable information - grounded in fundamental principles such as mass and...
Desulphurisation in the steel ladle requires a reactive slag with high CaO dissolution. Conventional slag fluxing agents applied during this secondary metallurgical refining step include calcium aluminate additives and fluorspar to maximise the dissolved CaO. However, calcium aluminate additives can have a high carbon footprint due to their energy-intensive production process and the use of...
The steel industry accounts for approximately 10% of global CO₂-equivalent (CO₂e) emissions, producing around 1.7 tonnes of CO₂e per tonne of crude steel. A transformation towards green steel production by replacing fossil carbon based materials and by using alternatives energy sources such as renewable electricity and hydrogen is essential. However, this transition involves significant...
