How to control the thickness of the steel strip for packaging during production

In order to ensure that the thickness reaches the required accuracy, it is necessary to ensure that the thickness of the auxiliary coil of the same specification reaches the target thickness, and to ensure that the thickness of the packaging steel strip is uniform (the same plate difference). Therefore, it is actually necessary to control these two control targets through two completely different but interrelated functions. The accuracy of the thickness is mainly determined by the thickness setting model. The task of setting up the model is to pre-set the roll gap, speed and tension of each frame before wearing the belt. According to the introduction of the packaging steel strip manufacturer, the difference between cold continuous rolling and hot continuous rolling is that the speed of the belt is very low, and the speed of the belt is increased to the rolling speed after the belt is worn, so the displacement of the cross section is accelerated, so it is necessary to adjust the roll The gap, the speed and tension of the acceleration part. The thickness will be determined by the accuracy of the set model and the adjustment of the acceleration part, and due to the coiling time correction of cold rolling, various model adjustments will be performed during the coiling and milking process, and the 'post-positioning' will be performed after the adjustment to increase Thickness accuracy. The accuracy of the thickness of the strip is mainly determined by the AGC function added after the start of the stable rolling section. The above is all about the steel belt for packaging.
