  • In the ironmaking process, adding organic binder replaces a portion of bentonite is a potential solution to improve the performance of the pellets. The interaction between the original bentonite (OB) and the organic binder was investigated. The results illustrate that the micro-morphology of the organic composite bentonite (OCB) became porous and the infrared difference spectrum was a curve. Additionally, the residual burning rates of OB and organic binder were measured, which were 82.72% and 2.30%, respectively. Finally, the influence of OCB on the properties of pellets were studied. The compressive strength of OCB-added green pellets (14.7 N/pellet) was better than that of OB-added pellets (10.3 N/pellet), and the range of melting temperature (173℃) was narrower than that of OB-added pellets (198℃). The compressive strength of OCB-added pellets increased from 2156 N/pellet to 3156 N/pellet with the roasting temperature increased from 1200℃ to 1250℃.

Abstract: In the ironmaking process, adding organic binder replaces a portion of bentonite is a potential solution to improve the performance of the pellets. The interaction between the original bentonite (OB) and the organic binder was investigated. The results illustrate that the micro-morphology of the organic composite bentonite (OCB) became porous and the infrared difference spectrum was a curve. Additionally, the residual burning rates of OB and organic binder were measured, which were 82.72% and 2.30%, respectively. Finally, the influence of OCB on the properties of pellets were studied. The compressive strength of OCB-added green pellets (14.7 N/pellet) was better than that of OB-added pellets (10.3 N/pellet), and the range of melting temperature (173℃) was narrower than that of OB-added pellets (198℃). The compressive strength of OCB-added pellets increased from 2156 N/pellet to 3156 N/pellet with the roasting temperature increased from 1200℃ to 1250℃.
