Description

结晶器铜管成型芯棒
技术领域
本实用新型涉及一种芯棒,尤其是一种结晶器铜管成型芯棒。
背景技术
现在所使用的结晶器铜管成型芯棒,芯棒为单层结构,芯棒采用40Cr合金钢材质制成,硬度高,加工难度大,锻打容易出现缺陷,容易出现裂纹,寿命短,而且40Cr合金钢价格较高,增加了生产成本。目前,还未有好的解决方案。
实用新型内容
本实用新型的技术任务是针对上述现有技术中的不足提供一种结晶器铜管成型芯棒,该结晶器铜管成型芯棒具有减小了加工难度,锻打时不容易出现裂纹等缺陷,增加了使用寿命,降低了生产成本的特点。
本实用新型解决其技术问题所采用的技术方案是:它包括芯棒本体,所述的芯棒本体的外层设置有一金属层,所述的金属层为硬铬镀层,所述的芯棒本体为45号钢材质。
所述的金属层的厚度为0.06-0.08mm。
本实用新型的结晶器铜管成型芯棒和现有技术相比,具有以下突出的有益效果:芯棒为双层结构,内层芯棒本体采用45号钢材质制作,芯棒本体的外层为硬铬镀层,减小了加工难度,锻打时不容易出现裂纹等缺陷,增加了使用寿命,降低了生产成本,使用方便等特点。
附图说明
附图1是结晶器铜管成型芯棒的结构示意图;
附图标记说明:1、芯棒本体,2、金属层。
具体实施方式
参照说明书附图1对本实用新型的结晶器铜管成型芯棒作以下详细地说明。
本实用新型的结晶器铜管成型芯棒,其结构包括芯棒本体1,所述的芯棒本体1的外层设置有一金属层2,所述的金属层2为硬铬镀层,即在芯棒本体的外层电渡一层硬铬,所述的芯棒本体1为45号钢材质。
所述的金属层2的厚度为0.06-0.08mm。
当使用芯棒时,芯棒本体1的外层金属层2硬铬镀层与结晶器铜管内侧相接触,由于硬铬镀层硬度较高,不会损坏芯棒内层的芯棒本体1。内层芯棒本体1为45号钢材质,硬度比40Cr合金钢小,在进行锻打时不会出现工件开裂现象,而且价格较低,降低了生产成本。
除说明书所述的技术特征外,均为本专业技术人员的已知技术。
