在铝卷生产厂家的铝卷冷轧板形控制系统中，板形检测是实现板形自动控制的重要前提之一。对形状检测装置的主要要求是什么呢？
In the shape control system of aluminum coil cold rolling produced by aluminum coil manufacturers, shape detection is one of the important prerequisites to realize automatic shape control. What are the main requirements for shape detection devices?
(1)精度高，即能如实、准确地反映带材的形状，为操作人员或控制系统提供可靠的在线信息；
(1) High precision, that is, it can accurately reflect the shape of the strip and provide reliable online information for operators or control systems;
（2）适应性好，即可以测量不同材质和规格的产品，能在轧线的恶劣环境中长期工作而不出现故障或降低精度；
(2) Good adaptability, that is, it can measure products of different materials and specifications, and can work in the harsh environment of the rolling line for a long time without failure or reduced accuracy;
(3)安装方便，结构简单，维修方便；
(3) Convenient installation, simple structure and convenient maintenance;
(4)不会对条带造成任何损坏。
(4) There will be no damage to the strip.

因此，铝卷厂家对冷轧铝卷的形状检测确实是一个比较困难的问题。板形本身受多种因素影响，板形缺陷表现形式多样，给精密检测带来困难。尤其是在进行张力轧制时，往往会掩盖平整度缺陷。在生产过程中，轧机的运行环境非常恶劣。剧烈振动、水、油、灰尘等介质的侵入，往往会降低检测精度，甚至损坏平面度检测装置。
Therefore, it is really a difficult problem for aluminum coil manufacturers to detect the shape of cold-rolled aluminum coil. The shape itself is affected by many factors, and the shape defects have various forms, which makes it difficult to detect accurately. Especially in tension rolling, flatness defects are often covered up. In the production process, the operating environment of the rolling mill is very bad. Violent vibration, invasion of water, oil, dust and other media will often reduce the detection accuracy, and even damage the flatness detection device.
此外要知道其实铝卷的加工方式有很多种，通过不同的加工方式，可以适应不同的使用环境。铝卷采用风冷方式存在弯曲问题，主要是我们需要控制风冷条件，使铝卷与空气接触的各个部分的传热系数相同，但因为壁厚或形状不一样。同理，各部分的散热速度不均衡，导致厚壁部分或空心管的散热速度比薄壁部分慢。在这种情况下，铝卷会出现一个空心部分，从而弯曲到空心部分。
In addition, you should know that there are many ways to process aluminum coils, and different processing methods can adapt to different use environments. The bending problem of aluminum coil by air cooling is mainly that we need to control the air cooling conditions so that the heat transfer coefficient of each part of aluminum coil in contact with air is the same, but because the wall thickness or shape is different. Similarly, the heat dissipation speed of each part is uneven, resulting in that the heat dissipation speed of thick wall part or hollow tube is slower than that of thin wall part. In this case, the aluminum coil will have a hollow part, which will be bent to the hollow part.
