| 摘 要： | 对比分析了QT400-18AL风电球墨铸铁件底座的本体以及附铸试块的力学性能、金相组织,结果表明：珠光体以及夹杂物的存在对铸件本体力学性能有不利影响,使本体性能与附铸试块相比存在很大的差异,需要对生产过程作严格的质量控制;珠光体体积分数越高,低温冲击值及其伸长率越低;石墨球直径越小,石墨分布越均匀,低温冲击值、伸长率以及抗拉强度越高;石墨球数增加,低温冲击值以及伸长率呈增加的趋势.

| Abstract: | The mechanical properties and microstructure of QT400-18AL grade nodular iron foundation casting of wind power generator and its attached test block was compared and analyzed.The results showed：pearlite and inclusions have disadvantageous effect on the mechanical properties of casting body that caused quite big difference between the properties of casting body and attached test block and made it＇s necessary to strictly control the production process;the higher the content of pearlite,the lower the low temperature impact toughness and elongation;the smaller the graphite nodules size and the more uniform the graphite nodules distributing,the higher the low temperature impact toughness,elongation and tensile strength; when nodule number increasing,the low temperature impact toughness and elongation tended increasing. |
