Description

一种线材退火设备
技术领域
本发明属于铜丝处理设备技术领域,尤其涉及一种线材退火设备。
背景技术
在实现本发明的过程中,发明人发现现有技术至少存在以下问题:
传统Y型母线采用废杂铜、锌、铝、硅等材料进行熔炼,产品冲击韧性和抗断裂性能差,硬度较低,易导致铜线断裂,产品质量差。传统退火工艺会导致铜合金表面氧化甚至烧损的问题。铜合金线材退火过程中,由于空气中含有大量的O2、CO2、H2O等,会使铜合金表面氧化,产生“脱锌”现象,造成制品表面粗糙、花脸、发红等缺陷,严重影响制品表面的光亮效果,必须经过酸洗后,才能进行下一步加工。而酸洗过程中会造成大量污水排放,不仅污染环境也增加环保处理成本。
发明内容
本发明所要解决的技术问题是提供一种对铜丝进行均匀化退火与去应力退火,消除了铜材合金内部的应力,确保铜合金线材表面的光亮,同时实现免酸洗,减少酸洗对环境的污染的线材退火设备。
为了解决上述技术问题,本发明所采用的技术方案是:一种线材退火设备,具有:
炉体,其为密封结构;
加热电阻,设置在所述退火炉体内,铜丝穿过所述加热电阻;
引导轮,设置在所述退火炉体内,所述引导轮引导所述铜丝穿过加热电阻并穿出所述退火炉体;
氨分解炉,其出气口通过管路与所述炉体内部连通;
抽气泵,通过管路与所述炉体内部连通。
所述氨分解炉通过管路接入所述炉体的上部,所述抽气泵通过管路接入所述炉体的下部。
所述炉体上设有供铜丝穿入和穿出的通孔,所述通孔上设有耐热密封圈,所述铜丝通过耐热密封圈穿入和穿出。
所述抽气泵和氨分解炉的管路上各设有一个阀门。
上述技术方案中的一个技术方案具有如下优点或有益效果,对铜丝进行均匀化退火与去应力退火,消除了铜材合金内部的应力,确保铜合金线材表面的光亮,同时实现免酸洗,减少酸洗对环境的污染。
附图说明
图1为本发明实施例中提供的线材退火设备的结构示意图;
上述图中的标记均为:1、炉体,2、引导轮,3、加热电阻,4、铜丝,5、氨分解炉,6、抽气泵,7、阀门。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
参见图1,一种线材退火设备,具有:
炉体,其为密封结构;
加热电阻,设置在退火炉体内,铜丝穿过加热电阻;
引导轮,设置在退火炉体内,引导轮引导铜丝穿过加热电阻并穿出退火炉体;
氨分解炉,其出气口通过管路与炉体内部连通;
抽气泵,通过管路与炉体内部连通。
氨分解炉通过管路接入炉体的上部,抽气泵通过管路接入炉体的下部。氨分解产生的氢气和氮气密度小于空气,因此氨分解炉接入炉体的上部,抽气泵接入炉体的下部,通过抽气泵从下部将空气抽出,上部慢慢通入氢气和氮气,使炉体内逐步充满氢气和氮气的保护气体。
炉体上设有供铜丝穿入和穿出的通孔,通孔上设有耐热密封圈,铜丝通过耐热密封圈穿入和穿出。
抽气泵和氨分解炉的管路上各设有一个阀门。通过阀门控制管路的通断。
经过均匀化退火与去应力退火后,消除了铜材合金内部的应力,使铜杆中的元素进行固态扩散,消除或减轻晶内偏析,有效解决目前铜合金线材易断的缺点。
采用罩式炉氨分解保护气氛进行铜合金线材的退火,使炉体内充满氨分解产生的氢气和氮气,形成保护气氛,防止铜丝表面氧化。确保铜合金线材表面的光亮。同时实现免酸洗,减少酸洗对环境的污染。
采用上述的结构后,对铜丝进行均匀化退火与去应力退火,消除了铜材合金内部的应力,确保铜合金线材表面的光亮,同时实现免酸洗,减少酸洗对环境的污染。
上面结合附图对本发明进行了示例性描述,显然本发明具体实现并不受上述方式的限制,只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进,或未经改进将本发明的构思和技术方案直接应用于其它场合的,均在本发明的保护范围之内。
