Patent number: 11806769Abstract: A device for laterally guiding a metal strip (1, 13) running over a loop lifter (4, 12) between two roll stands (2, 3, 8, 9) of a finishing train. The device includes at least one main member module (14) extending in a direction between the roll stands. The module has a guiding plane (15), and also supports a number of wear members (18, 19, 20), each with a wear surface (21, 22, 23). Those wear members can be turned to a number of rotational positions. At least two wear members (18, 19, 20) are respectively arranged between one of the roll stands (2, 3, 8, 9) and the loop lifter, wherein, seen in the direction of the loop lifter (4, 12), the surface area of the wear surface (21, 22, 23) of adjacent wear member bodies (18, 19, 20) increases. During the operation of the device, at least one of the wear members is rotated while the metal strip (1, 13) is running to expose another area of the wear surface to the side of the strip.Type: GrantFiled: June 30, 2022Date of Patent: November 7, 2023Inventors: Klaus Frauenhuber, Walter Grabner, Friedrich Moser, Juergen Schiefer

Publication number: 20230226584Abstract: The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.Type: ApplicationFiled: December 14, 2022Publication date: July 20, 2023Applicant: Primetals Technologies Austria GmbHInventors: Heinz Fürst, Franz Hermann Glaser, Simon Grosseiber, Slaven Ilic, Lukas Preuler, Juergen Schiefer, Christian Strasser
