中钢衡重成功试制风电设备发电机球铁铸件［图］
发布日期：2024-02-07
8月4日下午，中钢衡重铸锻公司用球铁材质为湘电风能试制的风电设备发电机定子、转子实现成品交货，通过北京航天万源工业有限公司和湘潭电机股份有限公司电机事业部对其超声波探伤及超低温环境冲击功检测，其铸件致密度经超声波探伤检测达到了EN12680—3二级标准，-40℃超低温环境冲击功满足EN1563标准要求，其他各项性能全面满足要求。
湘潭电机有限公司是国内大型风力发电装备制造业的龙头企业，中钢衡重铸锻公司自2008年起投资约1000万元为其试制风电产品以来，已经为其成功生产130多台套叶片法兰、制动环、制动盘等高品质的风电小件产品，去年9~12月仅用3个月时间又一次性完成两套风电关键零部件机舱、轮毂、锥形支撑的试制任务，该公司不断用高质量和高技术迅速抢占国内高端风电产品市场。
风电设备电机球铁定子、转子属于高韧性铁素体球墨铸铁，因其安装的地点特殊，对铸件致密性及低温（超低温）冲击韧性要求甚高，其制造技术目前仅有国际市场少数企业所拥有，当前仅有两台样机在意大利运行。今年5月初，在国内两家顶级风电铸件生产企业试制半年尚未成功的情况下，铸锻公司毅然接受了湘电风能转包北京航天万源工业有限公司风电设备发电机关键部件定子、转子球铁铸件的试制任务。
此次铸锻公司追加投入100多万元试制费用，组成项目攻关小组，在没有任何外来技术支持的情况下，通过艰苦攻关，仅用3个月时间实现定子、转子球铁铸件试制成品交货且一次获得成功，其中木模和砂箱制作、造型与冶炼浇注、精整等工序试制工作仅用一个月时间完成。
