Improvement in quality and quantity indices of sinter with high proportion of limonite

In order to improve the quality and quantity indices of sinter with high proportion of limonite,the influence of factors such as binary basicity and calcareous flux on the quantity,strength and type of bonding phase as well as the quality and quantity indices of sinter were studied through micro-sintering test and sintering pot test based on the characteristics of blending ores for sintering.The experiment results show that the quality and quantity indices of sinter with high proportion of limonite can be improved through the following measures:the binary basicity of sinter increases to 2.0,the proportion of quicklime increases in a certain range,and the sintering negative pressure and the depth of the sintering bed increase properly.
