立窑水泥熟料显微结构特征

以陕西某水泥厂立窑熟料为研究对象,利用偏光显微镜对水泥正常熟料、过烧和欠烧熟料进行了显微结构分析,揭示了水泥熟料显微结构与烧结过程中室内温度、通风、氧分布等烧结工艺的关系。正常熟料尽管符合出厂条件,但由于烧结工艺实施不合理,使得熟料显微结构欠缺,导致熟料水化性能和抗压强度降低。研究结果表明,正常熟料、过烧和欠烧熟料的判定与C2S的干涉色高低有直接关系。研究结果可用于各水泥厂熟料质量检测和烧结工艺制定。

Microstructure Characteristics of Upright Kiln Cement Grog

Through micropolariscope study on normal clinker, overburning clinker and underburnt clinker fromvertical kiln of a Shaanxi’ s cement factory, this paper disclosures the relationship between clinker’ s fine textureand technological conditions. Even though the normal clinker agrees with the factory-condition, because of tech-nology system’ s irrational implement, the fine texture of clinker appears lack and results in physical property re-duction. The incomplete technological conditions in overburning process and underburnt process can be defined bythe interference color and texture of C3S.
