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。

补充资料：拔桩机
利用振动、静力或锤击作用将桩拔出地层的桩工机械。拔桩作业常采用相应的振动沉桩机、静力压桩机或双动汽锤,再配以桩架和索具,故也称振动沉拔桩机、静力压拔桩机。桩工施工中以振动拔桩较普遍,作业时,将振动拔桩机固装于桩头，通过弹簧吸振器和索具悬挂于吊钩下，开动拔桩机，振动器产生的振动，引起桩和土体共振，土体结构破坏，桩身与土体间摩擦力减小，同时收紧索具,将桩逐渐拔出。若采用偏心块式振动器,因沉桩和拔桩阻力方向不同，必须对偏心块进行调整。此种拔桩设备结构简单，拔桩效率高，有发展前途。液压拔桩机利用其夹桩器夹住桩头，液压缸强制顶压夹桩器，使之向上顶升一段距离,将桩逐段拔出,适用在粘土、砂土或含少量砾石的土层中拔工字钢或型钢桩。也有采用机械方法拔桩的，即由电动机驱动卷扬机，利用钢丝绳滑轮组的拉力将桩强制拉出地面。使用方便,成本低,但拔桩力不大、设备笨重、拔桩效率低，只适用于软土地层施工。利用双动汽锤拔桩，系将锤体倒置，固定于桩头，并悬挂于索具下，先将土中桩头晃动，减低桩和土壤间紧密度，然后开动汽锤，向上锤击振动，收紧索具，将桩逐渐拔出，可在各种土层中拔混凝土桩及其他桩。
