摘　　要：针对我国贫钛原料氯化转化率低、排放尾气含氯量高的问题,分析了影响氯化的主要因素,提出适于泥浆料返炉二次氯化的熔盐组分、反应温度、氯气浓度以及配碳比,经生产实践说明上述工艺参数范围对提高熔盐氯化法的氯化率,降低尾气的含氯量是有效的,为粗四氯化钛的生产提供参考依据。To solve the proplem of the low conversion rate of poor titanium chloride and high discharge of chlorine in tail gas, we analyzed the key factors that have influence on the chlorination of molten salt, and come up with composition of molten salt, reaction temperature, concentration of chlorine gas and C/O ratio which are suitable for slurry to return into secondary chloride in the furnace. The production practice shows that the range of main parameters of production technology helps to improve the chlorination rate of molten salt chlorination and reduce the amount of chlorine emission, which provides reference for the production of crude titannium tetrachloride
