1、鑄錠未均勻化處理,使鑄錠安排中分出的Mg2Si相無(wú)法在揉捏的較短時(shí)間內(nèi)重新固溶,形成固溶不充分而影響了商品功能;需求強(qiáng)對(duì)鋁卷鑄錠進(jìn)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(shí)溫度過(guò)低,揉捏速度太慢,鋁卷型材在揉捏機(jī)的出口溫度達(dá)不到固溶溫度,起不到固溶強(qiáng)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(jī)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(dá)不到規(guī)范請(qǐng)求;需求強(qiáng)加強(qiáng)鑄錠的質(zhì)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(fēng)機(jī)少,風(fēng)量不夠,導(dǎo)鋁卷致冷卻速度慢,不能使型材在較短的時(shí)間內(nèi)降到200℃以下,使粗大的Mg2Si過(guò)早分出,從而使固溶相削減,影響了型材熱處理后的機(jī)械功能;需求強(qiáng)化風(fēng)冷條件,有條件的工廠可設(shè)備霧化冷卻設(shè)備,以期到達(dá)6063合金冷卻梯度的較低請(qǐng)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(shí)效技術(shù)不妥、熱風(fēng)循環(huán)不暢或熱電偶設(shè)備位置不準(zhǔn)確,導(dǎo)致時(shí)效不充分或過(guò)時(shí)效;需求強(qiáng)合理斷定時(shí)效技術(shù),鋁卷準(zhǔn)確設(shè)備熱電偶,準(zhǔn)確擺放型材以保證熱風(fēng)循環(huán)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.
