Abstract

本发明公开了一种Hpb63-2铅黄铜线材生产工艺，工艺流程为：挤压至12.3mm→酸水洗→拉至9.5mm→半成品退火→拉至7.6mm→半成品退火→拉至5.8mm→半成品退火→拉至4.5mm→半成品退火→拉至3.2mm→半成品退火→拉至2.2mm→成品退火→拉制成品2.032±0.0254mm→检验→困料→入库。工艺简单，操作方便，易于控制，生产周期短。采用中间退火消除加工硬化，使其恢复塑性再继续加工，保证了其机械性能，制品表面光洁。

Description

Hpb63-2铅黄铜线材生产工艺
 
技术领域
本发明属于线材生产工艺，具体涉及一种Hpb63-2铅黄铜线材生产工艺。
 
背景技术
Hpb63-2铅黄铜属复杂黄铜，其铜含量在61.0％～64.5％，铅含量在1.3％～2.3％，铁杂质小于0.1％，其它杂质含量符合ASTM标准，余量是锌。国内生产工艺还未成型。
 
发明内容
为了克服现有技术领域存在的上述缺陷，本发明的目的在于，提供一种Hpb63-2铅黄铜线材生产工艺，工艺简单易控。
本发明提供的Hpb63-2铅黄铜线材生产工艺，工艺流程为：挤压至12.3mm→酸水洗→拉至9.5mm→半成品退火→拉至7.6mm→半成品退火→拉至5.8mm→半成品退火→拉至4.5mm→半成品退火→拉至3.2mm→半成品退火→拉至2.2mm→成品退火→拉制成品2.032±0.0254mm→检验→困料→入库。其中，酸水洗是在常温下，在含15％～25％硫酸水溶液中洗10～30min，控酸5min，高压水冲洗，洗净后干燥；半成品退火温度650～670℃，保温65～75min，氧化进行；成品退火温度630℃，保温2.5h，氧化进行。
本发明提供的Hpb63-2铅黄铜线材生产工艺，其有益效果在于，工艺简单，操作方便，易于控制，生产周期短。采用中间退火消除加工硬化，使其恢复塑性再继续加工，保证了其机械性能，制品表面光洁。
 
具体实施方式
下面结合一个实施例，对本发明提供的Hpb63-2铅黄铜线材生产工艺进行详细的说明。
