A Preliminary Study on Reduction Degradation of Iron Ore Sinter Using Sinter Analogue and X-ray Micro-computed Tomography (MCT)

The increase of hydrogen (H2) proportion in the blast furnace affects the reduction degradation of the ferrous burden materials. As one of the main ferrous burden materials, iron ore sinter consistently shows higher degradation than other burden materials. The typical analysis of reduction degradation of sinter utilises standard tests and microstructure observation from the sample after reduction. However, this method has limitations in terms of the view being limited in 2D and the analysis using the same samples was difficult.
