摘要
通过调整氧化硅微粉加入量和活性氧化铝微粉的类型 ,研究了Al2 O3-SiC -C浇注料的流动性和流动性衰减以及可工作时间的变化。结果表明 :在浇注料流动性相近的情况下 ,随着氧化硅微粉加入量的增加 ,加水量显著降低 ;浇注料的流动性与所引入的活性氧化铝微粉的特性密切相关 ;氧化硅微粉加入量的增加有助于延长浇注料的可工作时间 ;浇注料流动性的衰减呈现出先缓慢后迅速降低直至凝结的特点 。
Effects of microsilica addition and reactive alumina type on flowability,flow decay and working time of Al 2O 3-SiC-C castables for BF trough were investigated.The results show that at a targeted self flow value of (180±10) mm, water demand markedly decreases with increased microsilica addition.The nature of reactive alumina has a strong influence on flowability of the castables.Higher microsilica content shares a longer working time.The flow decay goes gradually until the working time and then drop down abruptly.
