The pollution caused by sintering process in China’s iron and steel industry is especially serious. Strengthening the research on sintering process is of great significance to sustainable development. In this paper, a physical model of flue gas full-cycle sintering process is established, and the new process is simulated and calculated. The distribution of material layer temperature, flue gas temperature and flue gas composition content is obtained, and compared with the conventional sintering process from the five aspects of material layer maximum temperature, high temperature duration, material layer cooling speed, sintering time and emission reduction. The results show that the new process can increase the maximum temperature of the upper material layer, improve the uniformity of the temperature distribution in the material layer, and can enrich SO 2 , improve the removal efficiency of pollutants, and reduce emissions.
