Rolling mill, and device and method for determining the rolling or guiding gap of the roll stands or guide stands in a multi-stand rolling mill

Rolling mill (1, 2, 3, 4) having an arrangement of roll stands (10) and/or guide stands (18) carrying rolls (15) and/or guides (17) along a center line (20), disposed in a rolling direction, and having a device for determination of the rolling gaps or guiding gaps of the rolls or guides, which comprises a camera (60), wherein the rolling mill (1, 2) has an input side (12) and an output side (13), wherein a holder (53) for the support (50) of a comparison scale (40) is disposed at the other of the input or output sides (12, 13).

Apparatus for determination of the roll gaps or guide gaps of the roll stands (10) and/or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), comprising a support (50) vertically attached to a comparison scale (40).

Apparatus for determination of the rolling gaps or guiding gaps of the roll stands (10) or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), having an image processing apparatus (70) that determines the rolling gap or guiding gap, in each instance, from an image of a reference means (30) taken by a camera (60), a comparison scale (40), and at least one roll (15) or guide (17), wherein the position of the reference means (30) in the image is determined and equated with a center line (20) of the rolling mill (1, 2, 3, 4), and proceeding from this, the position of the roll (15) or guide (17) is determined by way of the comparison scale (40).

Method for determination of the rolling gaps or guiding gaps of the roll stands (10) or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), having a center line (20), wherein first, a camera (60) is disposed at one of the input or output sides (12, 13), and subsequently the rolling gap or guiding gap of the stands (10, 18) is determined, wherein before determination of the rolling gap or guiding gap of the stands (10, 18), the camera (60) is aligned to the center line (20), using mechanical reference generators, and at least one reference scale is recorded by way of the camera (60) and passed to image processing.

Method for determination of the rolling gaps or guiding gaps of the roll stands (10) or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), wherein a comparison scale (40) is positioned on at least one, preferably on the first and the last stand (10, 18), and subsequently the rolling gap or guiding gap of the stand (10, 18), in each instance, is determined, wherein before positioning of the comparison scale (40), a camera (60) is disposed on one of the input or output sides (12, 13), and a transmitter (35) for reference means (30), a reference generator and/or a reference scale is disposed at the other of the input or output sides (12, 13).

Method for determination of the rolling gaps or guiding gaps of the roll stands (10) or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), wherein a comparison scale (40) is positioned on at least one, preferably on the first and the last stand (10, 18), and subsequently the rolling gap or guiding gap of the stand (10, 18), in each instance, is determined, wherein before positioning of the comparison scale (40), a transmitter (35) for reference means (30) and/or a camera (60) is aligned on a center line (20) of the rolling mill (1, 2, 3, 4).

Method for determination of the rolling gap or guiding gap of the roll stands (10) or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), wherein a comparison scale (40) is positioned on at least one, preferably on the first and the last stand (10, 18), and subsequently the rolling gap or guiding gap of the stand (10, 18), in each instance, is determined, wherein comparison scale (40) is positioned on each stand (10, 18), carried from an input side (12) or from an output side (13) of the rolling mill (1, 2, 3, 4).

Method for determination of the rolling gaps or guiding gaps of the roll stands (10) or guide stands (18) in a multi-stand rolling mill (1, 2, 3, 4), wherein a comparison scale (40) is positioned, and subsequently the rolling gap or guiding gap of the stand (10, 18), in each instance, is determined, wherein light is passed through the comparison scale (40).

Method for determination of the rolling gaps or guiding gaps of the roll stands (10) or guide stands (18) in a multi-stand rolling mill, wherein roll or guide positions are determined on-line, by way of measurement value generators, and the measurement value generators are previously calibrated in-line.
