主　　题：pellets organic composite bentonite softening-melting property interaction behavior 

摘      要：In the ironmaking process,the addition of an organic binder to replace a portion of bentonite has the potential to improve the per-formance of *** interaction between original bentonite(OB)and organic binder was *** indicated that the micromor-phology of organic composite bentonite(OCB)became porous and the infrared difference spectrum exhibited a curved *** addition,the residual burning rates of OB and organic binder were determined to be 82.72%and 2.30%,***,the influence of OCB on the properties of pellets was *** compressive strength of OCB-added green pellets(14.7 N per pellet)was better than that of OB-ad-ded pellets(10.3 N per pellet).Moreover,the range of melting temperature of OCB-added green pellets(173℃)was narrower than that of OB-added pellets(198℃).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℃.
