Abstract

In this study,physical,chemical and microscopic characteristics of celestine were investigated firstly. Then,the thermodynamic analysis of celestine reduction was discussed. And the experiments of celestinecarbon-containing pellets used in rotary hearth furnace process were studied. The results showed that it is feasible to deal with celestine by rotary hearth furnace direct reduction process. When the temperature is 1 200 ℃,C /O is 0. 8 and holding times is 20 min,the conversion rate of SrSO4in celestine is above 95%,the utilization rate of Celestine is nearly 100%. This study can provide theoretical and technical basis on economical and rational use of celestine.

转底炉直接还原天青石的试验研究

本文首先对天青石的物理、化学和显微特性进行了研究。然后，对天青石还原过程进行了热力学分析。并对天青碳球团在转底炉工艺中的应用进行了试验研究。结果表明，采用转底炉直接还原法处理天青石是可行的。当温度为1 200℃时，C /O为0。8、保温时间为20 min时，天青石中srso4的转化率达95%以上，天青石的利用率接近100%。本研究可为天青石的经济合理利用提供理论和技术依据。
