Abstract: A method and a vacuum-coating system (10) for coating a strip-shaped material (11), in particular made of metal, are disclosed. Thereby, the strip-shaped material (11) is moved over a conveying section (12) in a transport direction (T) and vacuum-coated within a coating chamber (14) in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (11), at least one trimming shear (38) is arranged upstream of the coating chamber (14), with which the strip-shaped material (11) is trimmed at at least one strip edge, preferably at both strip edges, in order to produce a constant width for the strip-shaped material (11) over its longitudinal extension.

Abstract: In a method for the online determination of at least one rolling parameter when rolling a rolling material rolled along a rolling line in a rolling mill including at least two rolls on a roll stand, the rolling material is guided past or through at least one measuring device during the rolling, which interacts with a rolling material variable of the rolling material, the rolling material variable being changeable along the length of the rolling material, and outputs a measurement signal, wherein: (i) the measurement signal is transferred into the frequency space, and the rolling parameter is determined from the measurement signal transferred into the frequency space, and/or (ii) a frequency inherent in the change of the rolling material variable is determined from the measurement signal, and the rolling parameter is determined on the basis of the determined frequency.

Abstract: A method for operating an annealing furnace to anneal a metal strip provides that, initially, at least one target material property (MPTarget) is specified for a point or a section of the metal strip after passing through the annealing furnace. In addition, information (E) on the metal strip is provided before or in the annealing furnace. A calculation of a target temperature distribution (TTarget) and/or a target speed (VTarget) of the metal strip in the annealing furnace is then carried out with the assistance of a computer-aided model as a function of the target material properties and the specified information. The target temperature distribution and/or target speed calculated in this manner is/are subsequently set in the annealing furnace in order to transfer the material property of the metal strip behind the annealing furnace to the desired target material property MPTarget.

Abstract: The invention relates to a method and a vacuum-coating system (10) for coating a band-type material (11), in particular made of metal. For this, the band-type material (11) is moved, via a conveying section (12), in a transport direction (T) and is vacuum-coated within a coating chamber (14), in which a vacuum is applied. As seen in the transport direction (T) of the band-type material (11), at least one flatness optimization device (39) is arranged upstream of the coating chamber (14), through which flatness optimization device the band-type material (11) can be guided. In this way, a desired flatness is generated for the band-type material (11).

Abstract: A heat-treatment method for controlling austenite content in steel during conveying, heating and cooling the steel though a furnace. The method includes heating the steel until reaching a first location, then cooling the steel until reaching a downstream second or third location in the furnace. First, a quality window of the austenite content having minimum/maximum values at the second or third locations is determined. Upstream from the second/third locations, temperature of the steel for the second/third locations is predicted by a heat-transfer equation and/or conveyance speed of the steel through the furnace. The austenite content is then predicted at the second/third locations by metallurgical/data-based modelling using the predicted temperature. The furnace temperature and/or conveyance speed is adjusted when the predicted steel austenite content for the second/third locations is outside the quality window, whereby after the furnace adjustment, the predicted austenite content for the second/third locations falls within the quality window.

Abstract: A measuring device that is able to function even in rough environments, for example under great heat or in environments in which water or steam is found, as is the case in rolling mills, among other environments, has a housing, a central measuring device that passes through the housing in a straight line, and a measuring coil that is disposed in the housing and encloses the measuring opening. The device has a coil carrier that is disposed in the housing radially outside of the measuring coil and carries the measuring coil.
