摘要
以轮毂为例,介绍对大型风力发电机球墨铸铁件生产工艺进行的试验研究。通过优化铸型工艺,采用适当的浇注系统和低温石墨化退火工艺,选择合理的化学成分,控制球化处理与孕育处理,可生产出各项性能指标合格的风电铸件。
Taking wheel hub as example, the investigation on the production process of heavy nodular iron castings used for wind turbine generator was introduced. By optimizing casting method, adopting proper gating system and risers, adopting low temperature graphitization annealing process, optimizing chemical composition, and strictly controlling nodularizing and inoculating processes, it is possible to obtain qualified heavy wind turbine generator castings with all properties meeting requirements.
