伞骨钢成型过程中分层的原因分析

Analysis on causes to laminar defect for umbrella bone steel in the process of forming

采用化学分析及微观组织分析的方法,对伞骨钢压扁后成型过程中所产生分层缺陷的原因进行分析。结果表明,钢带中部严重的碳偏析是导致在冷弯成U形伞骨时,形成钢带分层的主要原因。

Causes to the laminar defect of the umbrella bone steel occurring in the process of cold forming are analyzed by chemical analysis and microstructure analysis. Results show that the primary cause to the laminar defect of the umbrella bone steel in the process of cold bending to U-shape is band. the severe carbon segregation in the steel
