碳氮化钛粒度与熔渣粘度关系的研究

AN INVESTIGATION OF THE RELATIONSHIP BETWEEN THE PARTICLE SIZE OF TITANIUM CARBONITRIDE AND THE VISCOSITY OF BLAST FURNACE SLAG BEARING HIGH RITANIA

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。

n this paper the effect of particle size of TiC and TIN in high titania blast furnace slag on the viscosity of this type slag is discussed.The viscosity and melting termperature of the slag samples having dlfferent amount and size of TiC and TiN particle are measrued in the laboratory.Also the dispering pattern of TiC and TiN in slag samples has been analyzed by an image analysis device,The results show that the viscosity of the slags will increase with the increase of the amount of TiC and TiN added in the range of 0～8%. When the same amount of either TiC or TiN added,the smaller the particle size is,the thicker the slag is. But TiC has more effect on the slag viscosity than TiN when their amount in slag is equal and their particle sizes are approximate.
