酸洗是冷拔前一道重要的预处理工艺,影响酸洗效果的主要因素有酸液浓度、酸洗温度和酸洗时间等.本文以传动轴常用的冷拔材料45钢为例,利用正交试验法对酸液浓度、酸洗温度和酸洗时间等工艺参数进行优化,并对酸洗后的表面质量、材料塑性性能指标等进行评价分析.试验结果表明,当酸洗工艺参数为硫酸浓度17％、酸洗温度50℃、酸洗时间5 min时,45钢酸洗后的综合效果较佳.

Pickling is an important pretreatment process before the cold drawing, and the factors which influence the effects of pickling include acid concentration, temperature, pickling time, and so on. The cold drawn 45 steel materials which are commonly used in the drive shaft were taken as an example in this paper, it used the orthogonal experiment method to optimize the pickling process parameters such as acid concentration, pickling temperature, pickling time, and so on, then evaluated and analyzed the surface quality and the plasticity performance...
