借助SEM和EDS,对氯化前后的碳化渣进行工艺矿物学研究,特别是碳化钛的矿物学特征对氯化效果的影响及规律。系统研究了氯化温度、通氯时间、氯气浓度和粒度对氯化率的影响。结果表明:在580℃、氯气体积浓度为50%,通氯时间为30~40 min的工艺条件下碳化渣的氯化效果较佳,碳化钛的最高氯化率达到91.77%,为高炉渣提钛综合利用提供理论依据。 With the help of SEM and EDS, the technological mineralogy of carbonized slag before and after chlorination was studied, especially the influence and regularity of the mineralogical characteristics of titanium carbide on the chlorination effect. The effects of chlorination temperature, chlorine passage time, chlorine concentration and particle size on the chlorination rate were systematically studied. The results show that the chlorination effect of carbonized slag is better under the conditions of 580 ℃, the chlorine concentration is 50% and the passage time of chlorine is 30 ~ 40 min. The maximum chlorination rate of titanium carbide reaches 91.77% Provide a theoretical basis for comprehensive utilization of titanium.
