摘　　要：根据高炉灰特性,进行了高炉灰含碳球团添加黏结剂的试验研究。研究结果表明,不同种类黏结剂对高炉灰含碳球团的粘结机理不同,导致对高炉灰含碳球团生球、干球以及成品球的粘结效果不同。根据高炉灰含碳球团黏结剂的使用效果,应优先考虑使用复合黏结剂,其次考虑使用无机黏结剂水玻璃。研究结果为高炉灰高效使用提供了技术依据。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.
