    Abstract: A method for the automatic calibration of vertical rolls of a vertical rolling stand, each of which is supported in a vertical roll unit which is adjustable with respect to a predetermined center line of a plurality of components arranged in a rolling train, including the steps of a) moving the vertical roll units into a calibration position transverse to the center line against at least one stationary stop of the vertical rolling stand, which has a certain known position with respect to the center line, b) calculating a calibrated initial distance Akal between an outer edge of a vertical roll facing a rolled stock or the center line and the center line in the calibration position, and c) adjusting the vertical roll units to a defined operating position.

    Abstract: A thin-film treatment apparatus for treating viscous material includes

    a process housing oriented at an incline of at most 20° with a heatable and/or coolable housing casing, which surrounds a housing interior forming a material treatment space,
    an inlet nozzle arranged in an inlet zone of the process housing to introduce the material to be treated into the material treatment space,
    an outlet nozzle arranged in an outlet zone of the process housing to discharge the treated material from the material treatment space, and
    a drivable rotor shaft arranged in the material treatment space and extending coaxially for producing a material film on the inner surface of the housing casing and for conveying the material in the direction of an outlet zone.


    The rotor shaft includes at least one lift element arranged on the rotor shaft body, for producing a lifting force in the direction of the rotating rotor shaft body.

    Abstract: The present invention relates to a method for correcting placement errors in a photolithographic mask comprising a substrate and structures formed on the substrate, the method involving at least one local density change, preferably a plurality of local density changes, each of which defines a pixel, being introduced into the substrate by use of a laser beam in order to correct placement errors of the structures, wherein in an examination step, an incidence surface of the mask, via which the laser beam radiates into the substrate, is examined for contaminations and, in regions in which a contamination of the incidence surface has been ascertained in the examination step, no laser irradiation or a laser irradiation with at least one changed laser beam parameter takes place, the laser beam parameter(s) being changed such that no damage to the incidence surface or near-surface regions occurs in the case of an interaction between laser beam and contamination.

    Abstract: A system for the thermomechanical rolling of long semi-finished steel products includes a first rolling unit; a second rolling unit, arranged downstream of the first rolling unit; a first thermomechanical sizing block, arranged downstream of the second rolling unit; a second cooling device, arranged between the second rolling unit and the first thermomechanical sizing block; a cooling-bed, ring-laying and/or coil-winding device, arranged downstream of the first thermomechanical sizing block; a third cooling device, arranged between the first thermomechanical sizing block and the cooling-bed, ring-laying and/or coil-winding device; and a structure-sensor device, which is arranged between the first thermomechanical sizing block and the cooling-bed, ring-laying and/or coil-winding device, and can be used for determining directly in the ongoing process a martensitic structure, in particular a proportion of martensite in percent by area, in the thermomechanically rolled long semi-finished steel product or in the steel product.

    Abstract: A precise shearing process can be made possible, with a cost-advantageous embodiment of extrusion residue shears, if the shearing forces and the shearing movement are applied or carried out in as compact and targeted a manner as possible. This can be implemented, in the case of a suitable embodiment of the corresponding extrusion residue shears or of the corresponding method, in each instance, by a suitable embodiment of the drive train that belongs to the shearing movement, by pulling of the related shear blade, by a shearing drive that is separate from positioning and/or by suitable regulation.

    Abstract: A cooling device for cooling a metallic product has at least one cooling bar with a plurality of spraying regions which are adjacent in pairs defined by one or more moveable partition walls. Each spraying region has at least one spray nozzle for spraying a coolant onto the metallic product. A control device controls a pump and valves for individually adjusting pressure and/or volume flow of the coolant in each of the spraying regions. The one or more partition walls divide the interior of the cooling bar into at least two chambers, each of the spraying regions being assigned to a different one of the chambers. The partition wall is shaped at least approximately in accordance with a temperature distribution along a width section of the metallic product before it enters the cooling device. The partition wall is arranged in the cooling bar over this width section.
