Effects of Metallization Degree of DRI on the Yield and CO2 Emission in Reduction Shaft Furnace Process

Reduction shaft furnace process is one of the future directions for low-carbon ironmaking. Different parameters can affect the yield and CO2 emissions. In the present work, the effect of metallization degree (MD) of direct reduced iron (DRI) on the yield and CO2 emission in reduction shaft furnace process was calculated by thermodynamics, considering the partial oxidation of coke oven gas (COG). The results indicate that (1) at a reduction temperature of 850 °C and an MD of 90
