대대형42 CrMoS4원강단재쉬화출현조정、위씨조직적원인진행분석표명，냉각방식급쉬화개질시산생조직결함적주요원인。우화쉬화공예가이유효개선조직、세화정립화제고역학성능，만족생산기술요구。
After the analysis for coarse grain and widmanstatten organization of large -size 42 CrMoS4 forging steel by quenching , it was found that main cause of structure defect is that cooling and quenching medium was unreason -able .Optimizing quenching process can improve the microstructure , mechanical properties and grain refinement ef-fectively, and meet production requirements .
