It is considered by examination and analysis that the main causes of brittle fracture in drawing and lower specific elongation of finished wire are local martensite existence for alloy elements’segregation, carbon segregation leading net cementite and the continuity of metal being destroyed by high nonmetal inclusion; the transverse crackles of steel wire surface are due to the deep.
借助金相组织观察和电子探针检测,对PC钢丝生产中出现的质量问题进行研究,检测和分析认为拉拔脆断和成品钢丝延伸率低的主要原因是合金元素偏析导致局部马氏体存在、碳偏析引起网状渗碳体及严重的非金属夹杂物破坏金属的连续性;钢丝表面横裂主要是轧钢过程中折叠的表面氧化铁皮较深,或拉拔过程中润滑不良造成局部过热,导致表层产生马氏体引起的;钢丝表面划伤主要由线材出现耳子和椭圆度过大以及拉丝模安放不正所致。
