讨论了高钛型高炉渣中ＴｉＣ，ＴＩＮ颗粒的粒度对其粘度的影响；在实验室测定了不同粒度的ＴｉＣ，ＴｉＮ在不同配加量（０～８％）下的高钛型高炉渣粘度和熔化性温度。用图像分析仪对ＴｉＣ和ＴｉＮ在渣样中的分散形态进行了分析，实验结果表明：在实验范围内，随ＴｉＣ，ＴｉＮ配加量增加，炉渣粘度增加；配加量相同时，无论是ＴｉＣ还是ＴＩＮ，细粒度较粗粒度对炉渣变稠作用更为明显；粒度接近且配加量相同时，ＴｉＣ较ＴｉＮ的变稠作用明显。 The effects of particle size of TiC and TIN on the viscosity of high-titanium blast furnace slag were discussed. The viscosity of high-Ti-type blast furnace slag with different particle sizes of TiC and TiN at different dosages (0 ~ 8%) was measured in laboratory And melting temperature. The results of the experimental results show that with the increase of TiC and TiN content, the slag viscosity increases with the addition of TiC and TiN, Or TIN, the coarser grain size of the slag is more obvious on the thickening of the slag; when the grain size is close to the same dosage and the same dosage is added, the thickening effect of TiC over TiN is obvious.
