摘　　要：耐火材料作为钢铁冶炼用高温窑炉的内衬,对其提高热效率、降低能耗起着至关重要的作用。近年来,先进钢铁冶炼用耐火材料轻量化的研究受到广泛关注。基于此,根据轻量化耐火材料的种类,综述了先进钢铁冶炼用轻量化耐火材料的研究进展,以期指导长寿轻量化耐火材料的设计和开发,促进先进钢铁冶炼用高温窑炉的节能减排。耐火材料的轻量化可通过引入轻量骨料和密度梯度的结构设计实现。轻量化耐火材料具有较低的热导率和体积密度,较好的隔热性能,可直接作为工作层使用。轻量化耐火材料的制备技术、种类及损毁机制尚需深入研究。Refractories,as the high-temperature furnace lining for the smelting of iron and steel,play a crucial role in improving thermal efficiency and reducing energy consumption in the industry.In recent years,the research on lightweight refractories for the smelting of advanced steel has been paid extensive attention.Thus,the research progress of lightweight refractories for the smelting of advanced steel based on the types of lightweight refractories were reviewed,in order to guide the design and development of long-lived lightweight refractories and promote the energy conservation and emission reduction in high-temperature furnaces for the smelting of advanced steel.The lightweight of refractories can be achieved by the introduction of lightweight aggregates or the design of a density gradient structure.Lightweight refractories have low thermal conductivity and bulk density and good thermal insulation properties,which can be directly used as working linings.The preparation technology,types,and damage mechanism of lightweight refractories still need to be further studied.
