在鋁卷制做的全過程中，以便協(xié)助更改它的樣子，鋁卷生產(chǎn)廠家都須對它開展高溫加溫解決的，在高溫的情況下它便會較為軟，其樣子也較為非常容易產(chǎn)生一些轉(zhuǎn)變，在樣子調(diào)節(jié)好以后，就可以將它的溫度給減少出來，使其維持一定的強度，可是一些狀況，在高溫制冷進行以后，鋁卷會出現(xiàn)一些打卷難題，這是怎么回事呢
In the entire process of aluminum coil production, in order to assist in changing its appearance, aluminum coil manufacturers must carry out high-temperature heating to solve it. In high temperature conditions, it will be relatively soft and its appearance is very easy to undergo some changes. After adjusting the appearance, its temperature can be reduced to maintain a certain strength. However, in some cases, after high-temperature cooling, Aluminum coils may encounter some rolling difficulties, what is the reason for this
制冷時候出現(xiàn)彎折狀況，緣故為：一般風(fēng)冷式的標(biāo)準(zhǔn)下，鋁卷的每個部位與氣體觸碰的傳熱指數(shù)均差不多，但由于厚度或樣子不一樣，各部位的熱管散熱速率不平衡，鋁卷生產(chǎn)廠家導(dǎo)致薄壁部或中空管的熱管散熱速率比厚壁部慢，導(dǎo)致它在制冷時候出現(xiàn)向中空部位或壁厚偏厚的部位坎坷的狀況。
The reason for the bending phenomenon during refrigeration is that under the standard of air cooling, the heat transfer index of each part of the aluminum coil is similar to that of the gas contact. However, due to the different thickness or appearance, the heat dissipation rate of each part of the heat pipe is uneven. The aluminum coil manufacturer causes the heat dissipation rate of the thin-walled or hollow pipe to be slower than that of the thick wall part, resulting in bumpiness towards the hollow or thicker wall parts during refrigeration.
彎折緣故及全過程以下：
The reasons for bending and the entire process are as follows:
1、厚壁一部分溫度降低快，先造成收縮力，薄壁一部分或中空管一部分溫度降低慢，基本上沒有收縮力
1. A part of the thick wall temperature decreases quickly, causing shrinkage force first. A part of the thin wall or hollow tube temperature decreases slowly, and there is basically no shrinkage force
2、厚壁一部分截面較小，造成的收縮力較小，或被光纜牽引機驅(qū)動力清除
2. A portion of the thick wall has a smaller cross-section, resulting in less shrinkage force or being removed by the driving force of the fiber optic cable traction machine
3、離去光纜牽引機，溫度再次降低
3. Leaving the fiber optic cable tractor, the temperature drops again
4、薄壁一部分或中空管一部分截面很大，伴隨著溫度降低慢慢造成很大收縮力，厚壁一部分溫度已大幅度降低，已不造成收縮力或收縮力較小
4. A thin-walled part or a hollow tube with a large cross-section, accompanied by a gradual decrease in temperature, causes a significant contraction force, while a thick wall part has a significant decrease in temperature, no longer causing shrinkage force or a small shrinkage force
5、鋁卷橫截面上遭受的收縮力尺寸不勻，沿擠壓成型方位往薄壁一部分或中空管一部分彎折。
5. The shrinkage force on the cross-section of the aluminum coil is uneven in size, and it bends towards a thin-walled part or a hollow tube part along the extrusion forming direction.
