摘　　要：对典型蠕变曲线的特征 ,蠕变理论以及影响耐火材料蠕变变形的因素等作了综述。根据Al2 O3 -SiO2 系耐火材料蠕变性能研究的现状和进展 ,分析指出 ,在Al2 O3 -SiO2 系耐火材料中 ,高铝 (Al2 O3 ≥ 70 % )低蠕变制品的生产技术目前是比较成熟的 ,而对于低铝 (Al2 O3 ≤ 5 0 % )低蠕变制品的研制和生产 ,还需要采取一定的技术措施。The review is confined to the low creep refractory development in the Al 2O 3-SiO 2 system.The characteristics of typical creep curve,theories relating to creep performance and factors affecting refractory creep property are discussed.The situation and development of low creep refractory in the Al 2O 3-SiO 2 system over 20 years are reviewed.It is found that the manufacturing technology for low creep refractories with high alumina content(Al 2O 3≥70%)in Al 2O 3-SiO 2 system is well developed, however,the production of superior creep resistant refractories with low alumina content (Al 2O 3≤50%) is still difficult as long as the factor of cost effectiveness is concerned.
