大规格厚壁挤压材在线淬火可行性研究

Feasibility study on on-line quenching of large size thick wall extruded material

铝合金挤压材固溶淬火一般有两种形式,在线淬火和离线淬火。在线淬火一般适用于6×××系和铜元素含量较低的7×××系合金小规格挤压材或薄壁型材。对大规格厚壁挤压材在线淬火的可行性进行了的相关试验和分析,阐述了大规格厚壁挤压材实现在线淬火达到的必要条件。

The solid solution quenching of aluminum alloy extrusion material is generally in two forms,online quenching and offline quenching.On-line quenching is generally suitable for small size extrusions or thin-walled profiles of 6×××series and 7×××series al⁃loys with low copper content.The feasibility of on-line quenching of large-size thick wall extruded material is tested and analyzed,and the necessary conditions for on-line quenching of large-size thick wall extruded material are expounded.
