摘要
分析了铝型材表面晶粒粗大的原因。表面粗晶与铸棒晶粒度,挤压温度、挤压比、模具设计制作等因素有关,与铸锭Zn含量无关,避开临界变形量是消除粗晶的主要措施。
The cause of surface coarse grain of aluminium profile is analyzed. It relates to the billet grain, extrusion temperature, extrusion ration, and extrusion die, having nothing to do with Zncontent. The main precaution against surface coarse grain is to avoid critical strain.
