摘　　要：通过分析铝合金TTP曲线,扭曲敏感度曲线和冷却速率的关系,提出了复杂截面铝型材在线淬火过程需要一个合适的冷却速率。研究得出:复杂截面铝型材在线淬火装置的冷却速度需要可分区段控制和周向多路冷却差异化调节,提高了复杂截面铝型材的产品性能,并减小了铝型材变形程度。By analyzing relationship between TTP curve,contortion sensitivity curve and cooling rate of aluminum alloy,a suitable cooling rate has been put forward for on-line quenching of aluminum profile with complicated section.The research concluded that cooling rate of on-line quenching device for aluminum profile with complicated section was supposed to sectional control and circumferential multipath cooling difference adjustment,which improved products performance and reduced deformation degree of aluminum profile with complicated section.
