In the ironmaking process, the addition of an organic binder to replace a portion of bentonite has the potential to improve the performance of pellets. The interaction between original bentonite (OB) and organic binder was investigated. Results indicated that the micromorphology of organic composite bentonite (OCB) became porous and the infrared difference spectrum exhibited a curved shape. In addition, the residual burning rates of OB and organic binder were determined to be 82.72% and 2.30%, respectively. Finally, the influence of OCB on the properties of pellets was investigated. The compressive strength of OCB-added green pellets (14.7 N per pellet) was better than that of OB-added pellets (10.3 N per pellet). Moreover, the range of melting temperature of OCB-added green pellets (173°C) was narrower than that of OB-added pellets (198°C). The compressive strength of OCB-added green pellets increased from 2156 to 3156 N per pellet with the increase in roasting temperature from 1200 to 1250°C.

在炼铁过程中，添加有机粘合剂来代替一部分膨润土有可能提高球团矿的性能。研究了原始膨润土（OB）和有机粘合剂之间的相互作用。结果表明，有机复合膨润土（OCB）的微观形貌变得多孔，红外差谱呈现弯曲形状。此外，OB 和有机粘合剂的残留燃烧率分别为 82.72% 和 2.30%。最后，研究了OCB对球团矿性能的影响。添加 OCB 的生球团的抗压强度（每球 14.7 N）优于添加 OB 的球团（每球 10.3 N）。此外，添加 OCB 的生球团的熔化温度范围（173°C）比添加 OB 的球团（198°C）更窄。
