摘要(Abstract)：

研究了二元碱度对微晶铸石晶化行为及抗折强度的影响。在Facts age热力学计算的基础上,借助扫描电镜(SEM)和X射线衍射仪(XRD)对微晶铸石的析晶行为和显微结构进行了分析。结果表明:高炉渣碱度在0.90～1.20时,微晶铸石的主晶相为钙铝黄长石和镁黄长石,析晶温度应控制在1100℃以下;炉渣碱度为0.96时,可以获得晶粒分布较为均匀、致密的显微结构;随着碱度的提高,微晶铸石抗折强度呈现先升高后降低的趋势,碱度为0.96时抗折强度达到峰值,为40.08 MPa,当碱度超过0.96时,晶界面积逐渐变小机械强度降低,碱度1.20时抗折强度仅有3 MPa。

关键词(KeyWords)： 高炉渣;碱度;微晶铸石;析晶;抗折强度
