1、铸锭未均匀化处理，使铸锭安排中分出的Mg2Si相无法在揉捏的较短时间内重新固溶，形成固溶不充分而影响了商品功能；需求强对铝卷铸锭进行均匀化处理。
1, the inhomogenization treatment of ingot can make the Mg2Si phase separated from ingot arrangement unable to re solve in a relatively short time during kneading, resulting in inadequate solid solution and influence on commodity function, and strong demand for homogenization of aluminum coil ingot.
2、铝卷揉捏时温度过低，揉捏速度太慢，铝卷型材在揉捏机的出口温度达不到固溶温度，起不到固溶强化效果；需求合理操控铝卷揉捏温度和揉捏速度，使型材在揉捏机的出口温度保持在较低固溶温度以上。
2, when the low temperature aluminum roll kneading, kneading speed is too slow, not to roll aluminum profiles of solid solution temperature at the outlet temperature of kneading machine, not to the solid solution strengthening effect; the reasonable demand for aluminum roll kneading manipulation temperature and kneading speed, the profiles in the kneading machine outlet temperature maintained at a minimum solution temperature above.

3、铸锭成分不合格，铸锭中的Mg、Si含量达不到规范请求；需求强加强铸锭的质量管理。
3. The ingot components are not qualified, the content of Mg and Si in ingot can not reach the standard request, and the quality management of ingot is strengthened.
4、铝卷出口处风机少，风量不够，导铝卷致冷却速度慢，不能使型材在较短的时间内降到200℃以下，使粗大的Mg2Si过早分出，从而使固溶相削减，影响了型材热处理后的机械功能；需求强化风冷条件，有条件的工厂可设备雾化冷却设备，以期到达6063合金冷却梯度的较低请求。
4, aluminum coil outlet fan, air guide is not enough, aluminum volume caused by cooling speed is slow, cannot make the profile in the shortest time is reduced to 200 DEG C, the coarse Mg2Si premature separation, so that the solid solution phase reduction, affecting the mechanical function profile after heat treatment; strengthening cooling conditions demand conditions of the factory equipment, atomization cooling equipment, in order to reach the lowest request of 6063 alloy gradient cooling.
5、时效技术不妥、热风循环不畅或热电偶设备位置不准确，导致时效不充分或过时效；需求强合理断定时效技术，铝卷准确设备热电偶，准确摆放型材以保证热风循环晓畅。
5, with aging technology and hot air circulation is not smooth or thermocouple device position is not accurate, resulting in inadequate or aging aging; reasonable that aging technology demand is strong, the aluminum coil accurate equipment to ensure accurate placement of thermocouple, hot air circulation and profile.
