采用强制润滑拉拔技术、金相观察和力学性能测试,研究了拉拔模角、道次变形程度等对铝包 钢丝毛坯断面上各层间的变形分布和钢铝间结合性能的影响在强制润滑拉拔的条件下,减小拉拔模角有 利于降低不均匀变形程度;减小道次变形程度有利于改善润滑条件,但易使变形集中在线材表层;合理的 拉拔变形提高了变形均匀性和钢铝间的结合性能
The forced lubrication drawing technique, metallographic observation and mechanical property test were used to study the effect of drawing die angle and degree of deformation on the deformation distribution and the bonding properties between steel and aluminum in the blank section of aluminum clad steel wire. Under the conditions of lubrication and drawing, reducing the draft angle is conducive to reducing the degree of uneven deformation; reducing the degree of pass deformation is beneficial to improve the lubrication conditions, but it is easy to concentrate the deformation on the surface of the wire; reasonable drawing deformation improves the deformation Uniformity and bonding properties between steel and aluminum
