Problems solved by technology

[0008] On finished or processed or pending metal strips, slippery rollers can also significantly affect the quality
As the metal belt slips on the rollers, it damages its surface, which can also lead to production rejects

Embodiment Construction

[0041] figure 1 The industrial plant shown is designed as a processing line 1 for processing metal strip B (in particular cold-rolled strip). This processing line 1 may comprise several areas for processing the metal strip B, such as a rolling area, an area for coating the metal strip, an area for cleaning the metal strip, an area for thermal conditioning of the cold-rolled strip and other areas. they are figure 1 not shown in .

[0042] This processing line 1 has in particular at least one roller set 2 . In the exemplary embodiment, this roll set 2 has four rolls 3 which guide the cold strip. This roller set 2 is used to adjust the strip tension of the metal strip B in the processing pass 1. Roller sets 2 are arranged in particular between the areas of the processing line 1 in which different strip tensions are set for processing the metal strip B.

[0043] It is also possible to use roll packs with more or less than four rolls in the industrial plant 1 , especially for...

Abstract

The invention relates to an industrial plant (1), to a controller and / or regulator (5), to a machine-readable program code (7), to a storage medium (6), and to a method for controlling and / or regulating a slipping motion of a roller  (3, 3-1, 3-2) relative to a strip (B), particularly a cold strip to be processed in a metal processing unit, said strip being guided through a roller interconnection (2) comprising the roller (3, 3-1, 3-2) and at least one further roller (3, 3-1, 3-2) at an adjustable strip speed. By monitoring (21) the occurrence of the slipping motion by means of detecting at least one technical operating variable of the roller (3, 3-1, 3-2), and due to the fact that with the occurrence of a slipping motion of the roller (3, 3-1, 3-2), a current circumferential speed of the roller (3, 3-1, 3-2) and / or of at least one of the at least one further roller (3, 3-1, 3-2) and / or of the strip speed is changed (24, 25, 26, 27, 34) such that the current circumferential speed of the slipping roller (3, 3-1, 3-2) and the strip speed approach each other, it becomes possible to detect a slipping of a strip relative to a roller in a system, and to reduce or remedy the same, particularly during the operation of the plant.

Description

technical field [0001] The invention relates to a method for controlling and / or regulating the slipping movement of a roller relative to a strip. Furthermore, the invention relates to a control and / or regulating device, a machine-readable program code, a storage medium and an industrial plant for carrying out the method. Background technique [0002] The problem of roller slipping relative to the strip is dealt with for example in US 3764050 . [0003] Roll sets (also called tensioner sets) are as used in the present invention, e.g. when rolling metal strips, especially cold rolling, and in processing lines (e.g. when coating, pickling, etc. , heating or similar treatment). For this purpose, this set of rollers is used to adjust the strip tension of the metal strip to be processed. This strip tension, for example, has a major influence on the processing technology, for example reducing the thickness during rolling of the rolled stock. [0004] However, such roll sets are...
