摘要： A hot-rolling stand (10) for a hot-rolling mill comprises an adjusting device (12), which is intended for receiving a pair of work rolls (17) and for positioning work rolls (18, 19; 20, 21) of the pair of work rolls (17) in relation to one another to define a roll gap. In order to create a hot-rolling stand (10) that can be adapted as flexibly as possible, the adjusting device (12) is designed to interchangeably accommodate, in the pair of work rolls (17), different roll diameter ranges by means of mutually complementary work rolls (18, 19; 20, 21).

摘要： A modular rolling train, particularly a hot rolling train, preferably in conjunction with an upstream casting facility, and a method for operating a modular rolling train are described. The rolling train is standardized and modularized by dividing the rolling train into discrete units n and by modularization of the discrete units. The rolling train can be flexibly adapted to new requirements by exchanging a module.

摘要： A flatness measuring apparatus for measuring the flatness of a metallic strip, including a measuring roller which has a roller axis and which makes contact with the strip for the measuring the flatness. The measuring roller is connected to a cooling system, using which the measuring roller can be cooled. To ensure that a high degree of measuring accuracy can be maintained even at high temperatures, the cooling system has a nozzle bar that extends parallel to the roller axis. At least one spray nozzle is arranged on the nozzle bar, using which cooling medium can be sprayed on the surface of the measuring roller in a spraying direction. The spraying direction meets a surface section of the measuring roller, and the angle between the spraying direction and the tangent on the measuring roller at the location of the surface section is less than 30°.

摘要： An intermediate stand guide on a vertical roll stand of a rolling line for guiding the rolled material into a horizontal roll stand or out of a horizontal roll stand having at least one guide element, which is mounted on the vertical roll stand and is adjustable jointly with an adjustment movement of a vertical roll assigned thereto and which follows the adjustment movement of the vertical roll. The guide element is arranged set back transversely to the rolling direction by a predefined offset dimension to the edge of the vertical roll engaged with the rolled material. The guide element is connected to a traverse of the vertical roll stand and the offset dimension is pre-definable via an installation distance of the vertical roll to the traverse of the vertical roll stand.

摘要： The invention relates to a device (1) for the internal welding of pipes and profiles, comprising a cantilever arm (2, 2a), which is secured to a suspension (3), which cantilever arm can be inserted into the pipe or profile to be welded and on which a welding head (4) is displaceably attached, the cantilever arm (2, 2a) further comprising at least one laser (5) and at least one camera (6). To avoid the disadvantageous effects of magnetism and heat on the position of the welding head (4), the invention proposes that a laser (5) is attached on the suspension (3), and a camera (6) for observing the laser beam (5a) is attached on the end of the cantilever arm (3) or on the welding head (4). A correction signal is calculated from the change in position of the laser beam (5a) observed with the camera (6) and forwarded to a control unit for adjusting the welding head (4) by means of displacement devices (8, 9).
