摘　　要：中国每年产生大量含有较高铝硅含量的工业固废,有望成为冶金行业制备铝硅系轻质耐火材料的原料。总结了尾矿、冶金废渣、尘泥、粉煤灰、煤矸石等工业固废在制备轻质骨料方面的研究现状,通过对比总结了人工骨料替代天然骨料制备轻质耐火材料的性能优势,对制备轻质耐火材料中的轻质骨料微孔化与基质均匀化的相关研究进行了总结,阐明了使用工业固废骨料制备轻质耐火材料的合理性与发展前景,提出了开发固废骨料制备轻质耐火材料新工艺、新技术的需求,以及不断改善铝硅系轻质耐火材料的绝热性能与抗渣侵蚀性能的方式,以实现工业固废资源的高效利用以及冶金高性能耐火材料的轻量化和功能化发展。A large amount of industrial solid waste containing high aluminum-silicon content was generated in China every year,which was expected to become the raw material for the preparation of lightweight refractories in the metallurgical industry.The research status of industrial solid waste such as tailings,metallurgical slag,dust sludge,fly ash,and coal gangue in the preparation of lightweight aggregates was summarized.The performance advantages of preparing lightweight refractories by using artificial aggregates instead of natural aggregates were compared and summarized.The relevant research on the microporosity of lightweight aggregates and the homogenization of the matrix in the preparation of lightweight refractories was summarized,clarifying the rationality and development prospects of using industrial solid waste aggregates to prepare lightweight refractories.The need for developing new processes and technologies for preparing lightweight refractories from solid waste aggregates,as well as continuously improving the thermal insulation performance and slag resistance of aluminum-silicon lightweight refractories,was proposed to achieve efficient utilization of industrial solid waste resources and the lightweight and functional development of high-performance refractories in metallurgy.
