中文摘要: 考察了实验室条件下霞石石灰石的烧成温度,分析了烧成机理,同时研究核素在烧成过程中的损失。做出温度—熟料Al2O3溶出率曲线和温度—体积收缩率曲线。结果表明,该配料的烧成温度区间为1 267~1 350 ℃。烧成过程中,会伴随有少量Na2O、K2O的挥发。由于挥发产物返回备料,并最终进入熟料,因此,核素的此种少量挥发行为对核素平衡不产生影响。
Abstract:The sintering temperature of nepheline limestone was studied, sintering mechanism was analyzed, and the loss of radionuclide in the course of sintering was investigated. The curves of Al2O3 solubility and volume shrinkage rare vs. temperature were obtained. The results show that the sintering temperature range is 1267~1 350 ℃ accompanied by a small amount of Na2O, K2O volatilization. This volatilization behavior has no effect on nuclides equilibrium because those volatized products will return to materials preparing process and be recovered in the product of sinter.
