摘　　要：耐火钢是一种功能性的新型建筑用特殊钢材,钢材的耐火性能是指钢材耐高温的强度。介绍近年来耐火钢在我国建筑业的开发现状和工程应用,并对这类钢材的耐火性能和生产机理进行分析。试验研究表明:与普通钢相比,耐火钢在高温下的强度和弹性模量均显著提高,具有良好的高温性能。Fire-resistant（FR） steel is a new type of building steel material with special function and FR properties of steel material were thought to be high-temperature-resistant strength. The paper presents the recent development and engineering application of FR steels to building industry in China, analyzes its FR properties and production mechanism. The results of test study have shown, as compared with normal steels, that the high-temperature strength and elastic modulus of FR steels have obviously increased and FR steels have good high-temperature performance.
