Abstract In order to clarify the current development progress of the sintering granulation process and future development trends, the sintering granulation process and equipment of steel enterprises have been fully summarized and analyzed. Sintering granulation performance directly affects the air permeability of the materials layer and the distribution of quasi-particle structure and it is an important link in the sintering process of iron and steel enterprises. For a long time, the thermal performance of the iron ore sintering process has received more attention, while the granulation performance has not been paid much attention. In recent years, with the development of theory and technology, sintering granulation has received more and more attention from iron and steel enterprises and then many optimization measures of technology and equipment have been adopted for granulation. First, the significance of sintering granulation optimization was explained and then the optimization technologies made by domestic and foreign steel enterprises in the four aspects of raw material pretreatment, mixer equipment, quicklime digestion, and mixture moisture monitoring in recent years were summarized. The understanding of sintering granulation and the knowledge of emerging artificial intelligence technologies help to look forward to the trend of sintering granulation optimization in steel enterprises in the foreseeable future at the end.

Key words： sintering granulation technology and equipment optimization air permeability quasi-particle intelligent trend
