Research progress of sintering optimization ore blending method based on basic process performance of iron ore

The difficulty of sintering ore blending has significantly increased due to the complex and changeable supply of iron ore, which leads to the instability of sintering production and sinter properties. The traditional sintering ore blending method by sinter pot test is time consuming and laborious. Thus developing novel methods of optimization ore blending is an important way for improving the sintering ore blending efficiency and reducing costs in iron and steel enterprises. The methods of guiding optimization ore blending were introduced, which based on the basic process performance of iron ore at room temperature and high temperature, and the thermodynamic calculations. The main technical characteristics of these methods were analyzed, and the research directions of sintering optimization ore blending was prospected. The high temperature performance of iron ore is the core of the optimization ore blending method based on the basic process performance of iron ore. The relationship between the key basic process performance of iron ore and the sinter production and quality is found out, which is the key to improving the reliability of optimization ore blending.
