Experimental investigation and CFD study of direct reduction of iron
Direct reduction of iron ore (DRI) is an important advancement in the ironmaking industry, due to its high productivity and low investment. Compared with conventional blast furnace iron production, DRI without costly coke-making and pollution sintering processes possess enormous benefits (Seetharaman, 2005, Small, 1981).The worldwide DRI production in 2021 is up to …
