在整个生产过程的铝轧制,为了帮助改变它的外观,花纹铝卷生产厂家必须在高温加热解决方案,在高温的情况下它会更加柔软,外观也很容易产生一些变化,调整后,它可以将温度降低出来，使其保持强度，但是有些情况，在高温制冷后，会出现一些铝卷轧制的问题，这是怎么回事呢?
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?
打卷的原因及整个过程如下:
The reasons and the whole process of rolling are as follows:
1、厚壁部分温度下降迅速，引起收缩力，薄壁部分或空心管部分温度下降缓慢，基本没有收缩力;
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、部分厚壁断面小，造成收缩力较小，或被电缆牵引车的驱动力拆下;
2. Some thick wall sections are small, causing small shrinkage, or are removed by the driving force of the cable tractor;
3、离开电缆牵引机后，温度再次降低;
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，随着温度的缓慢降低造成很大的收缩力，部分厚壁温度已经大大降低，没有造成收缩力或收缩力小;
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.铝卷在截面上所受的收缩力大小不均匀，沿挤压成型方向向一部分薄壁或一部分空心管弯曲。
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.
在加工过程中发生打卷问题，原因如下:一般在风冷的标准下，接触到的每一个部位的铝盘管和气体的传热指标都大致相同，但由于厚度或外观不一样，不同部位的热管散热率不平衡，铝卷生产厂家在薄壁部分或空心部分的热管散热率比厚壁部分慢，造成它在冷却时来到空心部分或厚部分壁厚粗糙。更多内容就来我们网站咨询了解吧。
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.
