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) High precision, that is, it can accurately reflect the shape of the strip and provide reliable online information for operators or control systems;
(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) Convenient installation, simple structure and convenient maintenance;
(4) There will be no damage to the strip.
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.
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.
We have generally understood the main requirements of aluminum coil manufacturers for the shape inspection of cold-rolled aluminum coil and other precautions. We also need to maintain more in daily use, so that it can be used more smoothly. If you have any questions, please come to our website http://www.skyequiltedcards.com Consult.
