CHIRON: Towards a carbon-lean HIsarna ironmaking process
Influence of H2 enrichment, mineralogy and microstructure on smelting reduction of iron-bearing raw materials
In the CHIRON project the influence of H2 enrichment, mineralogy and microstructure on smelting reduction of iron-bearing raw materials will be investigate. The project goals are to gain deep understanding of the effects of increased hydrogen levels on the in-flight melting and pre-reduction of the fine iron ores in the HIsarna furnace; and to evaluate the role of hydrogen on microstructure and mineralogy evolution of different ore types. This will provide guidance for selection of ore feeds for industrial plants. The knowledge developed within the scope of the current project will also be utilized by integrating the kinetic data and model into Tata Steel’s computational models of the HIsarna process, for upscaling to a demonstration plant of 0.5 mt/a, and further to 1.0-1.5 mt/y full commercial scale.
