摘　　要：针对圆拉扁工艺生产黄铜拉链线伤模具及难镀色的问题,通过对样品分析、物理性能、金相组织检测,认为导致伤模具及难镀色的主要原因是在线退火方式导致圆拉扁工艺生产黄铜拉链线产品,晶粒细小,材料表面硬度高,易伤模具及难镀色。通过改变在线退火工艺为罩式炉退火工艺,可有效避免问题的出现。For round,flat technology to mold production brass zipper line and effect of plating color problem,through analysis,physical properties and microstructure of the sample testing,think it's difficult to lead to injury mold and plating color is the main reason of the online annealing methods lead to round,flat for brass zipper production line products,small grains,high surface hardness of materials,easy injury mold and plating color.The problem can be effectively avoided by changing the on-line annealing process to the hooded furnace annealing process.
