5A06铝合金薄壁管材冷轧裂口成因与工艺措施研究

Research on Crack Cause and Processing Measure for Cold Rolling of 5A06 Aluminium Alloy Thin-walled Tube

针对5A06合金薄壁管材在冷轧过程中产生裂口缺陷这一棘手问题,从挤压管坯料质量、管坯退火制度以及送料量等方面分析其产生原因,探讨防止或消除冷轧过程中产生裂口缺陷的方法。

Aiming at involved problems of the crack defects in 5A06 aluminium alloy thin-walled tube during cold rolling,this paper analyzes its cause from many aspects,including blank material quality of the extrude tube,annealing process of the tube blank and material feeding amount,explores methods to prevent or eliminate crack defects during cold rolling.
