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.
