摘要:

介绍了超超临界机组用的Super304H钢管的国内外生产现状,分析了国产Super304H钢管质量状况,包括化学成分、力学性能和金相特征。调查分析结果表明,目前国内已有多家企业具备了Super304H钢管的生产能力,国产与进口Super304H钢管相比,在某些指标上还存在一定的差距,但已能满足相关标准的要求。国产Super304H钢管已在国内超超临界机组中投入使用,应加强运行监督。

Abstract:

This paper introduced the Super304H steel tube’s production situation at home and abroad in ultra supercritical units, and analyzed the quality situation of domestic Super304H steel tube including chemical composition; mechanical property; metallographic characteristics. The investigation results show that many manufacturers in China have the production capacity of Super304H steel tube at present. Compared with imported Super304H steel tubes, the domestic ones have difference in some indicators, but have been able to meet the requirements of relevant standards. The domestic Super304H steel tubes have been applied in ultra supercritical units in China, whose operation should be under strengthened supervision.

Key words: ultra supercritical unit, Super304H steel tube, localization, chemical composition, mechanical property, metallographic characteristics
