摘　　要：铝包钢在生产过程中由于拉丝速度、拉丝粉流动性、模具内压力稳定性等问题的影响,导致了铝包钢单丝机械性能的不稳定性。针对上述问题改进生产工艺,通过改进拉丝方法提高单道压缩率以及低温时效处理的方法来实现。经过实验验证,这些措施完全可行,能够有效提高铝包钢线机械性能提高单线强度以及伸率也能够保证其性能的稳定性。In the production process of aluminum clad steel,due to the influence of wire drawing speed,drawing powder fluidity,die pressure stability and other issues,the mechanical properties of aluminum clad steel monofilament are unstable.In view of the above problems,the production process is improved by improving the drawing method,increasing the single pass compression ratio and aging treatment at low temperature.Through the experimental verification,these measures are completely feasible,which can effectively improve the mechanical properties of aluminum clad steel wire,improve the strength and elongation of single wire,and ensure the stability of its performance.
