Current status of lightweight refractories prepared from industrial solid wastes and their metallurgical applications
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.
