摘　　要：我国耐火原料资源丰富,特别是高铝矾土、菱镁矿和石墨,具有重要的国际地位和影响力。但是,我国矿山开采多数不规范,存在滥采乱挖现象,资源浪费严重且影响环境。此外,我国原料生产企业多数“小、散、乱”,存在生产设备落后与排放不达标的问题。近年来,我国进行了矿山开采规范整治,同时,我国耐火原料生产企业还进行环保改造和淘汰落后产能,导致了原料供应紧缺,价格大幅上涨,如高铝矾土、镁砂、鳞片石墨、碳化硅的价格波动幅度大,给耐火材料的生产造成重要影响。然而,通过整改与更新换代,我国耐火矿物的供应及原料生产逐步规范化,运行趋于稳定,耐火原料生产向自动化、规模大型化、高质量的方向发展,为我国耐火材料行业的稳定运行提供了有利环境。China is rich in refractory raw materials,especially bauxite,magnesite and graphite,which play an important role in the world. Currently,Chinese government is paying more and more attention to resources and environment. The management of mining areas has been strengthened,and refractory raw material producers in China have also updated the environmental protection facilities and abandoned the backward production capacity,resulting in a shortage of raw material supply and a sharp rise in prices. The prices of main refractory materials,such as bauxite,magnesia,flake graphite and silicon carbide,fluctuate greatly,which have an important impact on the production of refractories. A favorable environment for the stable operation of refractory industry will be provided depending on more orderly mining operations in China,more complete supply chain of refractory raw materials,and the production lines of refractory materials with high automation degree and large-scale.
