技术介绍
随着科技的发展与人文的进步,铝合金由于其材料特性决定了其在航空、航天、汽车、机械制造、船舶及化学工业中得到大量应用,这些行业对铝合金的可塑性及强度有着更高追求。铝合金铸件根据需求选择合适的热处理方法,以提高铝合金的力学性能,增加耐腐蚀性能,从而改善加工性能,从而获得尺寸稳定性。浇注铝合金铸件或铸锭时,由于冷却速度快,结晶在不平衡状态下进行,常常出现偏折及不平衡共晶体,第二相晶粒粗大以及硬脆相沿晶界分布等缺陷,使铝合金的强度、硬度及抗腐蚀性降低。为了消除上述缺陷,都要进行均匀化退火处理。均匀化退火处理就是将合金加热到接近熔点的温度,保持一定时间后,以缓慢速度冷却。铝合金均匀化退火处理中的冷却过程,需要用到铝合金退火冷却炉。根据中国专利201320176072.2公开的一种多功能铝合金冷却炉,其包括设置在炉体侧面的风冷系统、喷雾系统及设在炉体顶部的水冷系统。由于其喷雾系统设置多个口径较小的风嘴,大大增加冷却成本,同时,还存在空间利用不合理的缺陷。因此,急需要一种空间利用合理、降低冷却 ...
