Problems solved by technology
Although the current cold rolling mills are equipped with an online flatness AFC (automatic flatness control) control system, the strip cold rolling process generally adopts a relatively large uncoiling and coiling tension, and the strip is rolled before and after the cold rolling mill. Flattening, the shape "distortion" appears, resulting in various shape defects appearing in the offline detection although the actual online shape display is good
Therefore, the traditional equipment has certain functional defects, which can only guarantee rolling, but cannot guarantee that strips that meet the requirements can be rolled.

Embodiment
[0017] Please refer to figure 1 , an on-line device for controlling the shape of an off-line strip, including an uncoiler 1, a deflector roll 2, a rolling mill, and a coiler 4 arranged in sequence, and the rolling mill includes a back-up roll 31 and a work roll arranged between the back-up rolls 31 32. The back-up rolls 31 and the work rolls 32 are vertically arranged. Between the rolling mill and the coiler 4, a first tension roll set 51 and a second tension roll set 52 controlled in conjunction with the rolling mill are arranged to form a three-stage tension control mode and The strip material between the first tension roller set 51 and the second tension roller set 52 is in a state of no tension or slight tension. The micro tension in the present invention refers to a tension of 0-1 MPa. The linkage control between the first tension roll set 51 and the second tension roll set 52 and the rolling mill can better realize the coordinated control between the first tension roll ...

Abstract
The invention discloses a device for controlling the shape of an off-line strip in an on-line manner, and belongs to the technical field of cold-rolling mills. A first tension roll assembly and a second tension roll assembly which are controlled by a rolling mill in a linkage manner are arranged between the rolling mill and a coiling machine, so that a single tension control mode of an outlet section of the rolling mill is changed into a three-section type tension control mode; a strip between the first tension roll assembly and the second tension roll assembly is in a tension-free or micro-tension state, at the moment, the shape of the observed strip is equivalent to the shape of the off-line strip, and if the shape of the strip is not good, an operator of the rolling mill can adjust the shape of the strip in real time. While normal rolling tension and pass arrangement are not changed, the shape of the off-line strip can be observed and adjusted in the on-line manner, and therefore, the inspection capability and the control capability of the shape of the strip of a cold-rolling mill are improved effectively.
Description
technical field [0001] The invention relates to the technical field of cold rolling mills, in particular to an on-line device for controlling off-line strip shape. Background technique [0002] At present, with the requirements of industrial automation, the downstream manufacturers of aluminum alloy strips have continuously improved the shape requirements, and good shape has gradually become an important indicator for measuring aluminum alloy strips. Although the current cold rolling mills are equipped with an online flatness AFC (automatic flatness control) control system, the strip cold rolling process generally adopts a larger uncoiling and coiling tension, and the strip is rolled before and after the cold rolling mill. Flattening, the "distortion" of the plate shape appears, resulting in that although the actual online plate shape is displayed well, various plate shape defects appear in the offline detection. Therefore, the traditional equipment has certain functional d...
