Sintering ore accounts for about 70% of furnace charge in China's blast furnaces, and energy consumption of sintering process accounts for 8% to 10% of energy consumption in iron and steel production, so reasonable optimization of sintering ore blending process is conducive to increasing production and reducing consumption of iron and steel enterprises. Using the basic characteristics of iron ore sintering at high temperature to guide the optimization of ore blending is more in line with the production practice. The assimilation property in the basic characteristics reflects the difficulty of forming liquid phase between iron ore powder and CaO flux, and affects the mineral composition, cold state performance and metallurgical performance of sintering ore. In recent years, great progress has been made in related research. Firstly, the research history for assimilation property of iron ore powder, as well as the current assimilation detection methods and equipment are summarized, and the advantages and disadvantages of various methods are discussed. Then, the effects of different chemical components of iron ore powder on the minimum assimilation temperature are analyzed. The results show that the minimum assimilation temperature first decreases and then increases with the increase of SiO₂ and Al₂O₃ contents, the minimum assimilation temperature increases with the increase of MgO and (Al₂O₃+SiO₂+MgO) contents. For different Fe-bearing minerals, limonite has better assimilation than hematite, and magnetite has the worst assimilation. Finally, based on the previous studies, existing problems at present stage are summarized and discussed based on the sintering process, optimized ore blending and practical experience, and an attempt is made to propose the direction of related research in the future.
