The shaft furnace direct reductionelectric arc furnace (DREAF) route (Fig. 1) is the primary alternative to the BFBOF route, which reduces lump ore/pellets to direct reduced iron (DRI) primarily using natural gas (NG), and further converts the DRI in an EAF. The DREAF route significantly reduced the consumption of coke and coal while ...

Iron ore is one of the two essential inputs for producing direct reduced iron (DRI); the other being natural gas or another hydrocarbon fuel that can be reformed to create a reducing gas rich in CO and H2. Although direct reduction processes can operate with pellets having an iron content of 65% or lower, typical of blast furnace (BF)grade ...
