1、鑄錠未均勻化處理,使鑄錠安排中分出的Mg2Si相無法在揉捏的較短時間內重新固溶,形成固溶不充分而影響了商品功能;需求強對鋁卷鑄錠進行均勻化處理。
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、鋁卷揉捏時溫度過低,揉捏速度太慢,鋁卷型材在揉捏機的出口溫度達不到固溶溫度,起不到固溶強化效果;需求合理操控鋁卷揉捏溫度和揉捏速度,使型材在揉捏機的出口溫度保持在較低固溶溫度以上。
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、鑄錠成分不合格,鑄錠中的Mg、Si含量達不到規范請求;需求強加強鑄錠的質量管理。
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、鋁卷出口處風機少,風量不夠,導鋁卷致冷卻速度慢,不能使型材在較短的時間內降到200℃以下,使粗大的Mg2Si過早分出,從而使固溶相削減,影響了型材熱處理后的機械功能;需求強化風冷條件,有條件的工廠可設備霧化冷卻設備,以期到達6063合金冷卻梯度的較低請求。
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、時效技術不妥、熱風循環不暢或熱電偶設備位置不準確,導致時效不充分或過時效;需求強合理斷定時效技術,鋁卷準確設備熱電偶,準確擺放型材以保證熱風循環曉暢。
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.
