European Research of Secondary Metallurgy: with Emphasize on Connected Auxiliary Materials


During this lunch-to-lunch workshop, the past and present researches on the topic of secondary steelmaking will be presented. Presentations will be given by European experts including researchers from Swerea MEFOS.

DissTec – Valorisation and dissemination of technologies for measurement, modelling, and control in secondary metallurgy – is a continuation of the previous RFCS project VALEAF (Valorisation and dissemination of EAF technology) which focuses on disseminating the projects funded by RFCS on the subject of secondary metallurgy. Within the current project, results obtained in previous RFCS projects will be valorized and disseminated.

There have been significant numbers of research projects on secondary metallurgy technology within the RFCS programme over the past 25 years, aimed to improve the chain of process performance in terms of resource optimisation, productivity, flexibility and environmental impact. This effort contributed to the development of a number of models, technological solutions, and hardware and software tools. The objectives of DissTec are to promote the knowledge and various outputs derived from the European projects, clarify the efforts, obstacles and gains of the European industries and develop a road-map to promote the future research on the secondary metallurgy.

The workshop is intended for Swedish and European steel industry and research institutes.
