摘要

对超(超)临界机组国产与进口10Cr钢制汽轮机转子锻件的各项性能进行了对比试验。研究结果表明:国产和进口锻件的拉伸强度、硬度和金相组织无明显差异

但国产锻件的冲击韧度、断裂韧度明显低于进口材料

持久强度和低周疲劳性能也低于进口材料。应根据国产材料的性能特点

有针对性地制订国产转子的运行监督措施

如合理控制转子的启停次数及启停机时的升/降温速度等。

Abstract

The properties of domestic 10Cr rotor forging steel used for USC turbine were compared with imported one

including tensile strength

hardness

microstructure

impact toughness

room temperature(RT)fracture toughness

low-cycle fatigue

creep rupture strength.The results indicate that properties like tensile strength

hardness and microstructure of the two materials are similar

while properties like impact toughness

RT fracture toughness

creep rupture strength

low cycle fatigue of domestic rotor steel are obviously lower than those of foreign steel.In view of the inferior of domestic steel

special supervision measures should be taken

such as controlling the times of shutdown/startup and warming/cooling rate during that period.
