Description

铝青铜合金及其制备方法
技术领域
本发明涉及合金及其制备方法。
背景技术
目前，用于加工大型板式换热器片、炊饮具、家用电器制品中的一些镜面不锈钢板和钛钢板等的模具一般采用Cr12、Cr12MoV、T10A、Cr15、Cr-Ni等合金钢制造。由于铁基材料相互粘着倾向严重，在拉伸、压延不锈钢坯料时易发生粘模、划伤工件等现象，产品表面滑痕、划伤较重，需要后续抛光工序来对工件进行表面处理，模具损耗严重，修模次数较多。
发明内容
本发明的目的是减少不锈钢及钛钢镜面板片工件生产过程中的滑痕、划伤，提高产品的一级品率，减少模具损耗，提高生产效率。
铝青铜合金，按重量百分比计量其成分为：Cu75～82％，Al13～16％，Mn0.8～2.5％，Fe2.5～5.0％，Co0.2～2.0％，Ni0.4～2.0％，Zn0.4～1.2％，稀土0.2～2.5％，杂质≤1.0％；
上述铝青铜合金的制备方法为：按上述Cu75～82％，Al13～16％，Mn0.8～2.5％，Fe2.5～5.0％，Co0.2～2.0％，Ni0.4～2.0％，Zn0.4～1.2％，杂质≤1.0％的成分进行配料，将配好的原材料装入电炉中在大气气氛中进行熔化，留少量的铝作为预脱氧剂，熔清后吹气预精炼，加入预脱氧剂预进行脱氧，在1250℃保温，进行化学精炼并加入0.2～2.5％的纯稀土进行终脱氧，除渣，含气量检验合格后加入覆盖剂，在1260℃保温3～5分钟，除净渣子，在1160～1200℃之间进行浇注。
本发明的有益效果为：其成分中的铝和铁能提高合金材料的硬度、耐磨性，铜基合金中加入过量(超过固溶度)的铝、铁可以在合金中生成硬质的K相质点，细化合金晶粒，提高合金的硬度和耐磨、减磨性能。加入纯稀土可以净化合金、细化晶粒、强化钢铝固溶体，提高了合金的耐磨和耐腐蚀性能，并有脱氧和排渣能力。镍和钻为铜基合金有效的固溶强化元素，有效地提高了合金的强韧性。合金在铸态时由于成分偏析严重，需要固溶时效热处理后可使其性能满足加工和模具使用要求。发明用于加工大型板式换热器片、炊饮具、家用电器制品中的一些镜面不锈钢板和钛钢板的模具，充分发挥其导热性好、与不锈钢材料的抗粘着性好、良好的耐磨、减磨和耐腐蚀性能以及精细的纹理结构等优点，产品表面质量达到要求，可省去产品的后续抛光工序，产品破损率为外风。模具损耗少，生产20000件修模一次。
具体实施方式
本发明的高强耐磨铝青铜合金，按重量百分比计量其成分为：Cu75～82％，Al13～16％，Mn0.8～2.5％，Fe2.5～5.0％，Co0.2～2.0％，Ni0.4～2.0％，Zn0.4～1.2％，稀土0.2～2.5％，杂质≤1.0％；
按上述合金成分进行配料，将配好的原材料纯电解铜板，电解铝、电解镍、电解锰、电解锌、铁(选用光洁度较好的去油铁丝或铁钉)、电解钴等一次性装入中频电炉中在大气气氛中进行熔化(留少量的铝作为预脱氧剂)，熔清后吹入氮等惰性气体预精炼，加入预脱氧剂预脱氧，在1250℃保温，进行化学精炼并加入0.2～2.5％的纯稀土进行终脱氧，进行化学精炼，然后加入稀土进行终脱氧，耙尽渣子，含气量检验合格后加入覆盖剂保温，1260℃静置3～5分钟，扒净渣子，在1160～1200℃之间进行浇注。
铸件经过固溶时效热处理，加工后可以直接作为模具使用。
