Description
技术领域
本发明涉及一种电梯升降机举升机构用高强度锰铝合金材料。
背景技术
升降机是一种将人或货物升降到某一高度的升降设备，在工厂、自动仓库等物流系统中进行垂直输送时，升降机上往往还装有各种平面输送设备，作为不同高度输送线的连接装置。为了满足承载量大，升降稳定性好的特点，升降机的举升机构需要采用高强度锰钢矩形管制备。。
发明内容
本发明所要解决的技术问题是提供一种电梯升降机举升机构用高强度锰铝合金材料。
为解决上述技术问题，本发明是这样实现的
一种电梯升降机举升机构用高强度锰铝合金材料，含有以下重量百分数的合金元素：
硅0.005-0.015%、铁0.002-0.008%、Ag1.5-2.5%、锰10-20%、镁1-5%、锌5-15%、硒0.05-0.1%、钪0.05-0.1%、锆0.005-0.01%以及余量的铝。
以上各组份中，铁，能增加铝合金的尺寸稳定性和支撑性能，使其在高温下具有高强度、硬度，但过量的铁与铜形成Cu2FeA7组分而降低热处理效应所需的铜量；硅，与铁结合，防止铁与铜结合降低合金的拉伸性能；在本申请中，Fe、Si是杂质元素，不利于铝合金综合性能的提高，需要尽量减少其含量，加入的稀土元素Cr能与Fe、Si等杂志元素形成化合物熔渣，将其从熔体中排除，且稀土元素形成的金属间化合物作为第二相能有效增加铝合金的强韧性。 能改善含铁的硅铝合金的强度和延伸性；
铜，能够提高铝合金的强度、硬度，但会降低延伸性；镁能够提高铜铝合金的固熔热处理和淬火后合金的强度，使铝合金在室温下具有更高的强度和延展性能，但会降低拉伸强度。
在合金材料中添加锰能细化晶粒，阻碍基体晶粒长大和再结晶，显著提高铝合金的拉伸强度，但延伸率不降低，而且Mn弥散相可以降低基体中Zn原子的浓度，有利于形成具有保护作用的Al的氧化膜，提高铝合金的耐腐蚀性能，抑制铝合金焊接时的开裂，传统认为在Mn-Al合金中加入过量的Ag（大于0.5%）会造成非平衡共晶相体积分数增加，消耗主合金元素，在均匀化过程中难以充分消除，因而不利于提高合金强度，但少量的Ag（小于0.2%）不存在这些不利影响，但本发明加入适量的硒元素后可以克服该现象，加入的Ag含量为1.5-2.5%，用量易于控制，且进一步提高了铝合金的综合性能。
将以上组份采用反向挤压法制备电梯升降机举升机构（挤压速度18m/min,挤压温度450-550摄氏度），获得的举升机构在高冲击负载下，安全可靠，耐磨耐用，具有较高的抗剪强度和耐热性能，压力加工性能和可切削性能以及耐蚀性良好，可热处理强化，在退火和刚淬火状态下塑性良好。
