| Abstract Scope |
Hydrogen plasma smelting reduction (HPSR) is a mixed chemical (H2) - electrical (excitation with electrons) breakthrough carbon-neutral ironmaking process due to the advantages of short processes, energy saving and high efficiency reduction. In this work, the green iron samples reduced by HPSR with different exposure times were melted and probed by high-temperature confocal laser scanning microscopy (HT-CLSM). The melting, solidification and gas bubble removal processes were observed in-situ. Furthermore, the motion of non-metallic inclusion particles was found to be different at the surface of melted iron with different reduction time. This is due to inclusion phase changes from SiO2-based type to Al2O3-based type when the reduction time prolongs from 10 to 15 min. Al2O3-based inclusions are easy to be agglomerated to form a large one to remove. The knowledge obtained here aims to support the refining of HPSR iron samples towards sustainable steel production. |
