<p>Under the strategic framework of “carbon peak” and “carbon neutrality,” low-carbon blast furnace ironmaking has emerged as a pivotal direction for the development of sustainable metallurgical technologies. To elucidate the reaction behavior of hydrogen-rich blast furnace burden, the reduction behavior of ferrous burden above the soft melting zone and the coke gasification line were investigated in this study using the course interruption method. Firstly, the reduction degree of ferrous burden at different temperatures was calculated and the reduction process of pellets was analyzed by optical microscopy, and then, the coke microstructure and morphology were characterized by XRD, Raman, and SEM. The study shows that the reduction degree of ferrous burden and the gasification reaction rate of coke increase with the increase of temperature. At a temperature of 1200&#xa0;°C, the reduction degree of sinter was 94.56%; the reduction degree of pellets was 85.56%; the reduction degree of lump ore was 94.53%, and the gasification reaction rates of lower coke and top coke were 6.71% and 29.69%, respectively. Moreover, the analysis of the microstructure of the coke showed that the graphitization degree and pore space of the coke increased gradually with the increase of temperature, and the tendency of the top coke to increase was greater than that of the lower coke.</p> Graphical Abstract <p></p>
