As one of the important processes in the long process steel complex, sintering is characterized by high energy consumption and high pollution, so energy conservation and emission reduction in sintering is one of the key links to achieve the goal of “peak carbon dioxide emissions and carbon neutrality” in iron & steel industry. The main research and exploration works done by Meishan Iron & Steel in recent years in sintering energy conservation and emission reduction are emphasized, such as optimized sintering ore distribution technology, enhanced sintering technology with coke oven gas injection, vertical cooling technology for sintering ore and ultra-low emission control technology for sintering flue gas. Its overall application effect: the sintering solid fuel consumption (dry basis) and process energy consumption of Meishan Iron & Steel gradually decreased from 51.23 kg/t and 53.98 kgce/t to 48.90 kg/t and 45.77 kgce/t respectively, and sintering head flue gas SO₂, NO_x and mass concentration of particulate matter emissions (16% base oxygen, dry state) reached 2.31, 41.83, and 0.99 mg/Nm³, respectively. Although there is progress in indicators, a large gap between advanced enterprises at home and abroad still exists. In the context of achieving the "carbon peaking and carbon neutrality" goals and creating an environmental protection A-class enterprise, the development of key technologies for the sintering process and the development of green, low-carbon and high-quality development are still the focus of the next step.
