为了解决酒泉钢铁公司３号烧结机酸性球团烧结矿在烧结过程中负压偏高的问题，对添加不同配比的ＣａＦ２、ＭｇＯ和ＴｉＯ２的球团烧结矿粘结相的粘度、表面张力和熔点进行了测定。结果表明：ＣａＦ２、ＭｇＯ和ＴｉＯ２对酸性球团烧结矿粘结相均有降低粘度和表面张力的作用，其中ＣａＦ２的作用较为显著，而ＭｇＯ不但可以降低球团烧结矿粘结相的粘度和表面张力，还可以提高其熔点，并且随着ＭｇＯ配比的增加，粘结相熔体性质由长渣变为短渣，从而使烧结过程中液相存在的温度区间变窄，可以说从两个方面减小了对空气的阻力。
In order to solve the problem of high negative pressure in sinter sinter pellets of No. 3 sintering machine of Jiuquan Iron & Steel Co., Ltd., the viscosity, surface tension and the surface tension of the pellet sinter binder phase with different proportions of CaF2, MgO and TiO2 Melting point was measured. The results show that CaF2, MgO and TiO2 have the effect of reducing the viscosity and surface tension of acidic pellet sinter binder phase, and the effect of CaF2 is more obvious. However, MgO can not only reduce the viscosity and surface of the pellet sinter binder phase Tension, but also can increase its melting point, and with the MgO ratio increases, the nature of the melt phase of the binder phase from long slag into short slag, so that the liquid phase during sintering temperature range narrowing, it can be said from two Aspects reduce the resistance to air.
