在整個(gè)生產(chǎn)過程的鋁軋制,為了幫助改變它的外觀,花紋鋁卷生產(chǎn)廠家建議在高溫加熱解決方案,在高溫的情況下它會(huì)更加柔軟,外觀也很容易產(chǎn)生一些變化,調(diào)整后,它可以將溫度降低出來，使其保持強(qiáng)度，但是有些情況，在高溫制冷后，會(huì)出現(xiàn)一些鋁卷軋制的問題，這是怎么回事呢?
In the whole production process of aluminum rolling, in order to help change its appearance, the manufacturer of patterned aluminum coil must solve the problem of high temperature heating. It will be softer under high temperature, and the appearance is easy to change. After adjustment, it can reduce the temperature to maintain its strength, but in some cases, after high temperature refrigeration, there will be some problems of aluminum coil rolling. What's the matter?
打卷的原因及整個(gè)過程如下:
The reasons and the whole process of rolling are as follows:
1、厚壁部分溫度下降迅速，引起收縮力，薄壁部分或空心管部分溫度下降緩慢，基本沒有收縮力;
1. The temperature of thick wall part decreases rapidly, which first causes the shrinkage force. The temperature of thin wall part or hollow pipe part decreases slowly, and there is basically no shrinkage force;
2、部分厚壁斷面小，造成收縮力較小，或被電纜牽引車的驅(qū)動(dòng)力拆下;
2. Some thick wall sections are small, causing small shrinkage, or are removed by the driving force of the cable tractor;
3、離開電纜牽引機(jī)后，溫度再次降低;
3. After leaving the cable tractor, the temperature decreases again;

4、部分薄壁或部分空心管截面很大，隨著溫度的緩慢降低造成很大的收縮力，部分厚壁溫度已經(jīng)大大降低，沒有造成收縮力或收縮力小;
4. Some thin-walled or partially hollow tubes have a large cross-section, which causes a large shrinkage force with the slow reduction of temperature. The temperature of some thick walls has been greatly reduced, which does not cause shrinkage force or small shrinkage force;
5.鋁卷在截面上所受的收縮力大小不均勻，沿?cái)D壓成型方向向一部分薄壁或一部分空心管彎曲。
5. The shrinkage force on the section of the aluminum coil is uneven, and it bends to a part of the thin wall or a part of the hollow tube along the extrusion direction.
在加工過程中發(fā)生打卷問題，原因如下:一般在風(fēng)冷的標(biāo)準(zhǔn)下，接觸到的每一個(gè)部位的鋁盤管和氣體的傳熱指標(biāo)都大致相同，但由于厚度或外觀不一樣，不同部位的熱管散熱率不平衡，鋁卷生產(chǎn)廠家在薄壁部分或空心部分的熱管散熱率比厚壁部分慢，造成它在冷卻時(shí)來到空心部分或厚部分壁厚粗糙。更多內(nèi)容就來我們網(wǎng)站http://ssstlc.com咨詢了解吧。
The reasons for the coiling problem during processing are as follows: generally, under the standard of air cooling, the heat transfer indexes of the aluminum coil and gas at each part of the contact are roughly the same, but due to the different thickness or appearance, the heat dissipation rate of the heat pipe at different parts is unbalanced, and the heat dissipation rate of the heat pipe at the thin-walled part or hollow part of the aluminum coil manufacturer is slower than that of the thick wall part, causing it to come to the hollow part or thick part when it is cooled, and the wall thickness is rough.
