Abstract

Tensioning unit for a rolling apparatus (11), which includes at least one rolling stand (46), comprising a contact unit (13) provided with a tensioning roll (12) and rotatable around an axis of rotation (Z), an actuation element (26) to drive the contact unit (13), a detection unit (17) to measure the forces to which the contact unit (13) is subjected. The contact unit (13), the actuation element (26) and the detection unit (17) are disposed at least partly aligned with each other, one after the other, so as to define a main development of the column type of the tensioning unit (10).

Description

technical field [0001] The invention relates to a tensioning device for a rolling installation for detecting and adjusting the tension of a strip or sheet metal in an intermediate stand section between two adjacent rolling mills. Background technique [0002] Tensioning devices are known for hot-rolling equipment for sheet metal placed in an intermediate position between two adjacent rolling stands to detect and adjust the tension of the strip or sheet metal being processed in the intermediate stand section. under tension. [0003] In order to impart the desired properties to the product and to achieve high quality standards, the tension of the strip or sheet metal is monitored. [0004] For example, it is known that properties such as profile and flatness of a strip or plate depend on maintaining a proper and constant tension value throughout the rolling process, especially in intermediate stand sections where the strip or plate is not directly supported. [0005] Tension...
