摘　　要：原料粒度对熔盐氯化反应所得粗四氯化钛具有重要影响,当加入熔盐氯化炉的钛渣、石油焦粒度偏粗时,熔盐氯化炉生产运行的稳定性差,生产出的粗四氯化钛中溶解的COCl_(2)、Cl_(2)含量升高,在对粗四氯化钛蒸馏除钒过程中,馏出液中VOCl_(3)和AlCl_(3)含量容易超标。结合理论分析和生产实践,获得了保证熔盐氯化炉稳定运行的原料粒度分布控制范围。The particle size of raw material has an important effect on the crude titanium tetrachloride obtained by chlorination of molten salt.When titanium slag and petroleum coke are added to molten salt chlorination furnace with coarse particle size,the operating stability of molten salt chlorination furnace is poor,and the content of dissolved COCl_(2)and Cl_(2)increases in the crude titanium tetrachloride produced.In the process of vanadium removal by distillation of crude titanium tetrachloride,the content of VOCl_(3)and AlCl_(3)in distillate is easy to exceed the standard.Combined with theoretical analysis and production practice,the control range of raw material particle size distribution is obtained to ensure the stable operation of molten salt chlorination furnace.
