减少不锈钢管内折缺陷提高成材率

RESEARCH ON REDUCING INTERNAL FOLDS OF STAINLESS STEEL TUBES FOR THE PURPOSE OF INCREASING YIELD

本文对不锈钢管穿孔时产生内折缺陷的原因进行了详细分析。文中提出,只要制定合理的工艺参数,严格操作,内折缺陷会大大减少,成材率大幅度提高。

A deep analysis is carried out for the causes of internal folds of stainless steel tubes formed during piercing. It is emphasized that provided proper technological parameters are set up and opera- tion requirements are strictly followed, internal folds will be greatly reduced so as to enhance the yield considerably.
