The present invention provides a method for air bending a plate of metallic material such as steel which is characterised by having two bending steps, wherein the bending punch in the second bending step has a smaller radius and/or the die width (204) used in the second bending step is smaller than the die width (104) used in the first bending step. The method of the invention can achieve a significant improvement in the bendability of metallic materials, particularly high strength steels. The invention also provides new bending apparatus that are specifically adapted to carrying out the method of the invention, including a nested double die having a second narrower die (203) residing below and within the first die (103), and an adjustable die having a height adjustment means (either in the support, bending punch or both) capable of accommodating movement of the metallic material during the adjustment to form the second die width.

The five partners EFD (Norway), SSAB, Outokumpu, and University of Oulu (Finland), and WIAS (Germany) propose an EID programme on Mathematics and Materials Science for Steel Production and Manufacturing, where eight PhD projects are jointly carried out, providing a unique interdisciplinary and inter-sectorial training opportunity. The research is focussed on three major topics - induction heating, phase transformations in steel alloys, ladle stirring. Two theses concern hardening: one is the hardening of helical and bevel gears by an optimized single or multi-frequency approach and the other is a novel idea about the hardening of the inner surface of pipes. Two of the theses are related to induction heating applications in the production of high-frequency welded pipes and for pre- and post-heating in the thermal cutting of steel plates. Two theses are concerned with phase transformations during steel production and the final two theses are related to secondary metallurgy in the ladle, optimal alloying strategies and an inverse problem related to stirring efficiency. Despite the fact that most theses projects deal with established processes, they are not fully understood nor fully controllable from a quality point of view. Improved and optimized process control requires quantitative mathematical modelling, simulation and optimization of the complex thermal cycles and thermal gradients experienced by the processed material. Such models require an understanding of the behaviour of the materials from a materials science and phase transformations perspective. Tailored industrial on-site trainings, customized courses in physical modelling and testing of steels as well as numerical simulation of induction heating and flow phenomena combined with scientific research in carefully selected topics on the interface of materials science and applied mathematics will provide the early stage researchers with excellent qualifications to pursue a career in academia or industry.

The FReSMe project, From Residual Steel gases to Methanol, will produce a methanol that will be demonstrated in ship transportation. This green fuel will be produced from CO2, recovered from an industrial Blast Furnace, and H2 recovered both from the blast furnace gas itself, as well as H2 produced by electrolysis. The two different sources of H2 will enable (i) maximum use of the current residual energy content of blast furnace gas, while at the same time (ii) demonstrating a forward technology path where low carbon or renewable H2 become more ubiquitous. The project will make use of the existing equipment from two pilot plants, one for the energy efficient separation of H2 and CO2 from blast furnace gas, and one for the production of methanol from a CO2-H2 syngas stream. This can be realised with a small amount of extra equipment, including supplemental H2 production from an electrolyser and a H2/N2 separation unit from commercially available equipment. Methanol is a high volume platform chemical of universal use in chemical industry as well as applicable for fuelling internal combustion engines. As such it provides a promising pathway for the large scale re-use of CO2 to decarbonize the transportation and chemical sectors in Europe and decrease the dependence on fossil fuel imports. Production of methanol from CO2 offers the unique combination of scale, efficiency and economic value necessary to achieve large scale carbon reduction targets. The pilot plant will run for a total of three months divided over three different runs with a nominal production rate of up to 50 kg/hr from an input of 800 m3/hr blast furnace gas. This size is commensurate with operation at TRL6, where all the essential steps in the process must be joined together in an industrial environment. The project will address the new integration options that this technology has within the Iron and Steel industry and contains supplementary and supporting research of underlying phenomena.

STEPWISE is a solid sorption technology for CO2 capture from fuel gases in combination with water-gas shift and acid gas removal. The main objectives of the proposed STEPWISE project is to scale up the technology for the CO2 capture from Blast Furnace Gases (BFG) with three overall demonstration goals in comparison to state-of-the-art amine-based technologies: Higher carbon capture rate i.e. lower carbon intensity, 85% reduction Higher energy efficiency i.e. lower energy consumption for capture (SPECCA ), 60% reduction Better economy i.e. lower cost of CO2 avoided, 25% reduction The STEPWISE project will achieve this by the construction and the operation of a pilot test installation at a blast furnace site enabling the technology to reach TRL6 as the next step in the research, development and demonstration trajectory. Hence further reducing the risk of scaling up the technology. The STEPWISE project has the potential to decrease CO2 emissions worldwide by 2.1Gt/yr based on current emission levels. The conservative estimate is that by 2050, a potential cost saving of 750 times the research costs for this project will be realized each year every year, with a much larger potential. The overall objective is to secure jobs in the highly competitive European steel industry, a sector employing 360 thousand skilled people with an annual turnover of 170 billion.

Rail freight transportation is a system service where a multitude of players, participants and systems providers bear a high degree of responsibility for its attractiveness and performance. It shows high efficiency as transportation means, in terms of land use and energy consumption and low greenhouse gas emissions. However rails market share of freight transportation and its economic efficiency continues to be limited. Aimed at overcoming such uncertainty, this project addresses one of the most important key resources for further developing rail freight transportation: the optimization of the performance of the rail freight wagon. The continuous pressure on environmental issues and energy efficient transport is forcing the rail transportation sector to enhance the rail logistics services and to incorporate innovative solutions to improve load capacity to keep the best-in-class position and, therefore, acquiring a much privileged position beyond alternative terrestrial transport source, as truck transportation. Thus, aimed at optimizing rail freight transportation, the main objective of this project is to holistically address the aspects that may improve freight wagon performance: enhanced logistics, improved multimodal operative, higher load capacity, optimized filling/emptying time and flexibility to transport multi-products. This project aims to achieve such optimization by combining industrial expertise on the freight wagon design and construction, advanced materials for lightweight construction and logistics with the research capabilities to incorporate innovation solutions and optimize material performance.
