1. From the experiment study on the preparation of cold-bonded self-fluxed coal-containing pellets and their compress strength, it is concluded that the compress strength of three kinds of pellets are comparatively ideal:(1) self-fluxed coal-containing pellet with silica-magnesium-calcium compound binder(water glass+magnesia lime(2)self-fluxed coal-containing pellet with magnesium compound binder(magnesia cement+limestone powder(3) self-fluxed coal-containing pellet with calcium-aluminum magnesium-calcium...
    Self-fluxing ； Compound binder ；通过冷固结自熔性含碳球团的制备和抗压强度的研究，得出3种球团的抗压强度比较理想：①硅质-镁钙质复合粘结剂自熔性含碳球团；②镁质复合型粘结剂自熔性含碳球团；③钙铝质-钙镁质复合粘结剂自熔性含碳球团。其中，镁氧水泥自熔性含碳球团和高铝水泥自熔性含碳球团平均冷抗压强度分别为749N/个球和790N/个球。
