Under the background of carbon neutrality and carbon peaking, the iron and steel industry is facing new opportunities and challenges. As an important part of the long-process production of iron and steel, the sintering process is an inevitable requirement for the progress of iron ore sintering technology to reduce its total pollutant emissions, realize its low-carbon production process, expand its sintering function and achieve its high added value. The characteristics of the traditional ultra-low emission technology, the heating mode of sintering solid fuel and the technology of collaborative solid waste disposal in industrial furnace are reviewed. Then, the new technologies of low-carbon and low-cost deep purification, high-ratio hydrogen-rich fuel sintering and collaborative solid waste disposal in sintering are emphatically introduced, and the application prospect of the above technologies in realizing reduction of pollution and carbon emissions in sintering and the social benefits is prospected.
