A fundamental study was carried out on the high-temperature zone flow resistance during iron ore sintering. In present work, firstly, quartz sand was used to replace iron ores to investigate the impact of temperature if bed structure has no change; then a three-layer bed structure was used to explore the primary factors controlling high-temperature zone structure for airflow. The zone where tem...

During the granulation process of Iron ore sinter mixture, there are many factors affect the granulating effect, such as chemical composition, size distribution, surface feature of particle, and so on. Some researchers use traditional fitting calculation methods like least square method and regression analysis method to predict granulation effects, which exists big error. In order to predict it...

Sinter quality is a key element for stable blast furnace operation. strength and reducibility depend considerably on the mineral composition associated textural features. During sinter optical image analysis (OIA), it important to distinguish different morphologies of same such as primary/secondary hematite, types silico-ferrite calcium aluminum (SFCA). Standard red, green blue (RGB) thresholdi...

The synthesis and characterisation of SFCA-I compounds has been performed. is one the key bonding phases in iron ore sinter, influencing physical properties such as strength, reducibility, strength degradation during reduction. results reported herein extend understanding solid solution limits phase, with single-phase materials containing 2.71, 3.23 3.73 mass% Al2O3. These contain less Al2O3 th...
