As a new carbon-iron composite furnace burden,iron coke can promote the indirect reduction in the blast furnace,lower the temperature of the softeningand melting zone,improve smeltingefficiency,reduce coke ratio,and thus achieving CO₂ emission reduction. Therefore,in the context of carbon peaking and carbon neutrality,the development of low-carbon iron-making technology using iron-coke composite as a novel burden serves as an effective means to support the sustainable development of low-carbon blast furnaces. Based on the curent research status globally and combined with relevantresearchworkconductedbytheresearchgroup,thispaperelucidatestheprinciplesof low-carboniron-making using iron-coke composite,systematically reviews the preparation processes of iron-coke composite both domestically and internationally,clarifies its reaction behaviorin blast furnaces,and prospects futureresearchanddevelopmentdirections, aiming to promote the innovation,development,and aplication of iron-coke composite technology in the field of low-carbon iron-making in China.
