在鋁卷生產(chǎn)廠家的鋁卷冷軋板形控制系統(tǒng)中，板形檢測是實現(xiàn)板形自動控制的重要前提之一。對形狀檢測裝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，即能如實、準確地反映帶材的形狀，為操作人員或控制系統(tǒng)提供可靠的在線信息；
(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）適應性好，即可以測量不同材質(zhì)和規(guī)格的產(chǎn)品，能在軋線的惡劣環(huán)境中長期工作而不出現(xiàn)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)安裝方便，結構簡單，維修方便；
(3) Convenient installation, simple structure and convenient maintenance;
(4)不會對條帶造成任何損壞。
(4) There will be no damage to the strip.

因此，鋁卷廠家對冷軋鋁卷的形狀檢測確實是一個比較困難的問題。板形本身受多種因素影響，板形缺陷表現(xiàn)形式多樣，給精密檢測帶來困難。尤其是在進行張力軋制時，往往會掩蓋平整度缺陷。在生產(chǎn)過程中，軋機的運行環(huán)境非常惡劣。劇烈振動、水、油、灰塵等介質(zhì)的侵入，往往會降低檢測精度，甚至損壞平面度檢測裝置。
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.
此外要知道其實鋁卷的加工方式有很多種，通過不同的加工方式，可以適應不同的使用環(huán)境。鋁卷采用風冷方式存在彎曲問題，主要是我們需要控制風冷條件，使鋁卷與空氣接觸的各個部分的傳熱系數(shù)相同，但因為壁厚或形狀不一樣。同理，各部分的散熱速度不均衡，導致厚壁部分或空心管的散熱速度比薄壁部分慢。在這種情況下，鋁卷會出現(xiàn)一個空心部分，從而彎曲到空心部分。
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.
