Objective

The low nitrogen content required for highly ductile steel grades (strips, bars, wire) is not usually achieved in conventional, 100% scrap-based EAF steel-making. The aim of the research is to establish the feasibility and the features of an industrial process for producing low nitrogen (50 ppm and less) steels in the EAF, using scrap as iron source, in adapting technologies, which are already available (coal/oxygen injections, arc setting, bath stirring, etc.). This new ability of the EAF will enlarge the production range of the short, steel recycling route towards higher grade steels without the need to import special iron sources (pre-reduced ore) which are not yet produced economically in Europe.
