摘要
压缩机压圈在调质处理后的机械加工过程中 ,在压圈端面及内孔壁上发现了裂纹。对失效压圈及其原材料进行了高、低倍组织检验以及化学成分分析 ,结果表明 ,压圈原材料中心疏松及锭型偏析是导致裂纹形成的主要原因。
Macro and microscopic metallographic examination and chemical composition analysis of compressor pressing rings cracks and its raw material were conducted. The results showed that central porosity and ingot shape segregate were the major causes of the cracking.
