摘要
火电机组中高温受热面管氧化皮一直是研究人员重点关注问题,氧化皮对火电机组的安全、经济运行有着重要影响.文中列举五种(材质分别为T22、T91、T122、304、347HFG)典型高温受热面管材料,对其生成氧化皮的微观形貌、结构特点、生成机理以及剥落形式进行系统的归纳分析.通过这五种材料氧化皮生成机理分析,总结可以获得,普通铁素体钢,9-12Cr铁素体钢,300系列奥氏体钢和细晶奥氏体钢氧化皮的生成特点,该分析结果为电站金属材料研究人员提供一定的理论研究基础.
High temperature heating-surface tube oxide in fuel fired units is an important problem for the researcher. The oxide has great effect on the unit safe and economical service. Five typical materials （T22, T91, T122,304 and 347HFG） of high temperature heating-surface tubes were listed in the paper. The corresponding oxide micro-pattern, structure character, formation mechanism and exfoliation model were summarize and analyzed in detail. Based on the analysis of the five materials oxide, the character of common ferritic steels, 9-12Cr ferritic steels, 300-series austenitic stainless steels and fine-crystal austenitic stainless steels can be concluded. The research results will provide the theoretical foundation for the researchers of power station metal materials.
