The iron and steel metallurgy industry faces the question of how to replace carbon in iron ore reduction to reduce CO 2 emission in basic industries and achieve the expectation of "double carbon". This study investigates the reduction swelling of individual iron ore pellet under mixed H 2-CO atmospheres and at temperatures of 800–1000 ℃ by in-situ observation.
According to Yuan et al., the metallization degree of the reduced iron ore-straw fiber pellets was slightly lower than those of the bamboo char-iron ore pellets and the charcoal-iron ore pellets at 600–800 °C. However, it will reach a comparable metallization value to the other two pellets at temperatures above 1000 °C.
