    Abstract: Apparatus (1) for inspecting and sampling a wound coil (2) of metal strip (3) having a supporting arrangement for the wound coil (2). The supporting arrangement has at least two base rollers (4) arranged adjacent to one another. The rollers have roller axes (5) extending parallel to one another and onto which the coil (2) is placed for support. An inspection device (6) is arranged alongside the supporting arrangement. The inspection device (6) performs an inspection of the metal strip (3) at least when the metal strip (3) is a thin metal strip. A sampling device (10) arranged opposite the inspection device (6) with respect to the supporting arrangement, such that the supporting arrangement is located between the inspection device (6) and the sampling device (10). The sampling device (10) has a separating device (12) which takes a sample of the metal strip (3) when the metal strip (3) is a thick metal strip (3).

    Abstract: A cooled strand guide roller (1) mounted at more than one location for guiding a metal strand (S) in a continuous casting machine, and a method for cooling a strand guide roller (1) mounted at more than one location. An internally cooled strand guide roller (1) is mounted at more than one location. The height of the strand guide roller (1) is intended to be adjustable easily and quickly. The strand guide roller (1) has a collecting bar (7) for supplying the strand guide roller (1) with cooling water. The collecting bar (7) includes a plurality of brackets (10, 10a, 10b). Between two successive brackets (10, 10a, 10b), there is at least one coolant pipe (11) for fluidically connecting the brackets (10, 10a, 10b). An outer bracket (10a) has at least one first connection (8) for internal cooling of the cooled strand guide roller (1) and at least one second connection (9) for cooling the bearing blocks (4). The first connection (8) is fluidically connected to the ducts (3) of the individual rollers (2a, 2b) and the second connection (9) is fluidically connected to the bearing blocks (4) via the brackets (10).

    Abstract: A method measures the flatness of a metal product and an associated device. The method applies to a metal product, in the form of either a strip or a plate from a metallurgical processing line. The product to be measured being, by default, free of external traction. The method contains the following steps: a) illuminating a portion of a face of the product under uniform intensity; b) capturing an image of a light line of the illuminated portion; c) relatively moving the illuminated portion and the light line in a defined direction in relation to the product; d) repeating steps a), b), c); and e) collecting the images of lines in a two-dimensional distribution of intensities and selecting a strand direction of the product in which, if at least one wave of intensities is detected, a local amplitude variation of the wave delivers a local strand flatness defect value.
