Research groups


 


CASR consists of nine research groups from three faculties of the University of Oulu and from LUT University. The participating groups and their special areas of expertise are shown in the picture above.

The activities of Materials and Mechanical Engineering Unit are particularly directed to the production of steels as well as to their properties and service applications. Strategic spearheads are steel research, thermomechanical processing of high strength steels utilizing physical simulation, metallography and mechanical testing. Weldability and formability studies on steels represent the second major activity. The equipment available to the laboratory consists of two thermomechanical simulators, a laboratory rolling mill, a range of mechanical testing facilities as well as metallographic techniques. The extensive research work is performed in close co-operation with Finnish and foreign universities and research institutes and with the steel industry in Finland and abroad. The head of the unit is professor Jukka Kömi.

The mission of the Process Metallurgy Unit  is to carry out research on metallurgical and other high-temperature processes utilizing interdisciplinary solution models and scientifically newsworthy experimental activities and to produce for the metallurgical industry diploma engineers and doctors, who understand and master the phenomena of high-temperature processes and know the work environment of the metallurgical industry. The research activities of the laboratory based on the understanding of reactions, reaction kinetics, thermodynamics and mass and heat transfer phenomena in high-temperature processes. These research actions contain all the individual unit processes of steelmaking onwards from raw material handling to continuous casting of steel but is focused on four areas: (1)reducing agents and reduction metallurgy, (2) primary and secondary metallurgy, (3) recycling and sustainable metallurgical processes and (4) new measurement and treatment methods in metallurgy. The head of the unit is professor Timo Fabritius.

Nano and Molecularl Systems Unit NANOMO is a highly international research environment presently formed by four professors and around 40 other researchers. The focus is on molecular scale materials research and novel applications of spectroscopic and imaging techniques. The main external funding sources are European Union ERC and Horizon2020 programs, Academy of Finland and China Scholarship council. The unit coordinates the Finnish national participation to the MAX IV facility, participates to the planning and constructing of the FinEstBeaMS beamline and contributes to the European Free Electron Laser Eu-XFEL project. The head of the unit is professor Marko Huttula.

The Biomimetics and Intelligent Systems Group (BISG) in the Faculty of Information Technology and Electrical Engineering, has the mission to carry out long-term research on novel technologies and applications of intelligent systems. The research specifically focuses on the creation of dynamic models that enable monitoring, diagnostics, prediction and control of target systems (living and artificial) or operating environments. It has extensive experience in creating data mining solutions for steel mills, for instance a system for predicting the post-roughing mill temperature of steel slabs and data mining in hot strip rolling, prediction models for mechanical properties of steel as well as a method for scale defect identification on the steel strip surface. The aim of its Data Mining Group is to develop methods and tools for knowledge discovery and information retrieval from large data. In the steel industry, the results are utilized to improve the production efficiency of manufacturing processes. The head of the BISG is professor Juha Röning.

The focus areas of Research Group of Environmental and Chemical Engineering are sustainable production and energy, air pollution control, waste minimization, resources optimization and applications of computational techniques in process automation.. The research profile is divided evenly between separation processes, catalysis and surface science, and sustainable production and energy as well as control engineering. Topics specific to the steel industry include energy-efficiency in steel production, emission control and utilisation of by-products and wastes, and regeneration of CO2 in the iron making process. Experimental and computational research is carried out using laboratory tests, pilot plant trials, and in full scale in industrial processes as well as using CFD-based modelling. Data-analysis is giving basis for process modelling. Statistical methods, soft sensors, multivariate analysis and intelligent methods, for example neural networks and fuzzy logic, are utilized to model processes and to give better understanding of them to manage and control their behavior. The head of the unit is professor Risto Laitinen. Dr. Esa Muurinen is leading the steel industry specific group. Contact person for control engineering within steel industry is Dr. Jari Ruuska.

The Future Manufacturing Technologies  (FMT)  is focused mainly on manufacturing final plate products using high strength and ultra high strength steel. The main part of the group is located in Nivala at ELME Studio, which is one of the Network of expertise locations, but has researchers also at the campus of University of Oulu. Fields of interest cover laser and laser assisted processes, ultra high strength materials and their behaviour in workshop environment, manufacturing technologies of thin sheet and plate products, forming, high speed machining, cost effectiveness and automation, design for manufacturing prototyping and mechanical wear. The head of the group is Dr. Antti Järvenpää.

The Industrial Engineering and Management is organized into three units: Industrial management, Work sciences, and Quality and Project Management. The research of Business and Strategic Management is focusing on the problems and development of small and medium sized companies. Work science is the principal institute of ergonomics, user-centred design and work science in Northern Finland. It’ s approach to the design problems and solutions is multidisciplinary and it accommodates researchers with backgrounds in engineering, psychology, social sciences and education. The aim of Quality and Project Management is to achieve lasting competitiveness. Integral factors are customer focus and continuous improvement. The head of the department is professor Pekka Tervonen.

The research group of Steel Structures (LUT) is working on design and fabrication of metal structures for demanding energy efficient applications with governed emission control, life cycle management and recycling. By conducting theoretical analyses, numerical simulations and experimental tests, the focus is to study and create novel ideas and rules for design and fabrication procedures, especially for high and ultra-high strength steels. The facilities of the Laboratory of Steel Structures are at high-level in terms of static and fatigue testing, along with different measurements, of structural details, components or even full-scale products. The Steel Structures executes collaboration at several levels starting from the LUT, where laboratories of Steel Structures, Welding Technology and Laser Processing forms the Welded Metal Structures (WMS) unit, of which research topics include: performance of welded and additive manufactured structures, digitized life cycle control and process from idea to product, modelling and design of robotized welding systems as well as metallurgical analyses and simulations of materials subjected to welding, laser processing and/or additive manufacturing. At national level, the University of Oulu is one of the main partners in cooperation due to their high-quality research in terms of high and ultra-high strength steel materials. Furthermore, the international collaboration with universities and institutes working on a same field (e.g. Monash University, KTH Royal Institute of Technology, IIW, CEN) as well as industrial networking by means the HRO Design Forum is active. Thus, the research work, along with the close connection to metal and engineering industry, carried out by the Steel Structures is one remarkable reason on the fact that Finland is one of the leading countries in the world in terms of using and utilizing modern high and ultra-high strength steels and the advanced high-tech products made from these materials have an important role in the Finnish export industry. The head of the unit is professor Timo Björk.
