摘要
对两件有内孔壁折叠缺陷的进口接管进行了热返修。实践证明,先用吹氧方法清除折叠,再用合适的马杠扩孔。这样更易于得到符合质量及尺寸要求的锻件。
Two inlet nozzles with folding defect on bore wall have been repaired in heat.Practices improve that oxygen blast to eliminate folding first and then borehole enlargement by proper bar can obtain the forgings meeting the quality and size requirements.
