[0002] The five-roller tensile roller is an important component of the five-roller mill. In the process of cold-rolled thin plate production, the tensile roller is mainly used to measure the tension of the strip. The tensile roller is mainly used to measure the tension on the tensioned strip. It achieves this function by using the position change of the floating roller on the tensioned strip due to the gravity. This position change reflects the change of the strip tension, thus providing the operator with real-time information about the tension status.

[0003] In the process of five-roll steel strip continuous rolling, it is necessary to detect the scratches on the surface of the steel strip.

At this time, the surface of the steel strip is easily affected by the debris, which in turn affects the detection effect and cannot meet production needs. Therefore, a five-roll measuring roller scratch steel strip surface detection device is proposed to solve the above-mentioned problems. Utility Model Content
