Effect of Different Binder Addition on Strength of Carbon-containing Pelletized Blast Furnace Dusts

According to physical and chemical characteristics of blast furnace dusts,an experimental study on different binder for the carbon-containing pelletized dusts was carried out. The experiment results show that different binder has different mechanism for binding pellets,which leads to different binding effect on green pellets,dry pellets and finished pellets. According to using effects of the binders,it can be concluded that the best choice is the composite binder,followed by the inorganic binder of sodium silicate. This study can provide theoretical and technical basis for efficient utilization of blast furnace dusts.
