The sintering machine head ash has large output, abundant potassium resources, complex composition, and high alkali metal chloride salt content, which is a typical high-salt solid waste in the iron and steel industry. At present, domestic steel and iron works mainly use direct return sintering to treat sintering machine head ash, but this method will lead to equipment corrosion and reduced finished ore grade. Aiming at making suggestions on the industrial application and research direction of sintering ash disposal technology, the current fire and wet disposal technologies are summarized, the advantages and disadvantages of different types of technologies are compared, and the research progress and direction of each technology is analyzed. By comparing the fire and wet disposal technology, it is found that the fire disposal technology has a short process flow, simple operation and low cost; The wet disposal technology can recover salt products through wastewater pretreatment and resource utilization while realizing the harmlessness of solid waste, which is more suitable for the current environmental protection requirements and the characteristics of solid waste phase. After summarizing the characteristics of sintering machine head ash and the current disposal technology, the research direction of sintering machine head ash disposal technology in the future is prospected.
