| Abstract Scope |
Driving toward net-zero CO2 emissions in steel industry, both iron-making and steel-making should be more sustainable. While the sustainability of iron-making is supported by the prospering hydrogen-based direct reduction, research on the sustainability of alloying ingredients used in steel making has been limited. In this study, we applied a “green” FeMn pre-alloy, produced by a novel hydrogen pre-reduction and aluminothermic (HAlMan) process, as the Mn alloying ingredient in both medium- and high-Mn steel production. In order to elucidate the effect of this “green” FeMn on steel-making, two reference Mn sources, Electrolytic Mn and Medium Carbon FeMn, were also applied for making the steels with similar composition. Comparability between these steels were demonstrated by a thorough microstructure characterization, and mechanical testing. In summary, similar grade of steel properties can be achieved while utilizing the sustainable FeMn with low amount of impurity, reducing the overall energy consumption without compromising the steels’ performance. |
