As the Al 2 O 3 content increasing in iron ore, some problems presented in blast furnace (BF) processing, such as worsened burden permeability and slag viscosity. Injection of H 2 may improve the permeability and reduce the CO 2 emission of BF, because of its less density and higher reduction potential when temperature is higher than 820 °C. Therefore, the …
