Abstract: A method for coating a metal strip by means of a metallic substrate in a strip coating system, wherein the coating is carried out according to the principle of physical vapor deposition and the layer thickness is set via the parameters of the strip speed and the vaporization rate. It is provided according to the invention that in the event of a layer thickness change and/or a width change of the metal strip, the vaporization rate and the strip speed are changed simultaneously, so that the layer thickness change can be implemented directly independently of the thermal vaporization process.

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 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: A metal strip is guided on transportation rollers through a strip treatment installation. The installation includes successive strip movement control devices along a transportation direction. The strip movement control devices detect and adjust the position of the strip transverse to the transportation direction. A method for operating the installation includes: detecting the position of the strip transverse to the transportation direction by sensors of upstream strip movement control devices; identifying properties that influence the position of the strip transverse to the transportation direction of the strip by the sensors; assigning the identified properties of the strip to corresponding points or segments of the strip; and proactively adjusting the position of the strip transverse to the transportation direction at downstream strip movement control devices based on the properties for the corresponding points or segments of the strip identified by the upstream strip movement control devices.

Abstract: The invention relates to a method for the heat treatment of a metallic product (P), in particular a strip or sheet, in which the product (P) is controlled and/or regulated by means of a control and/or regulating device (100) controlled and/or regulated furnace device (110) is carried out at a predetermined speed in a conveying direction (F), the product (P) being heated up to a first point (I) and then up to a second location (H) or is cooled down to a third location (III). The method according to the invention is characterized in that an austenite content of the product P is predicted for the second location (H) or for the third location (III) and it is then checked whether this austenite proportion is within a desired target range, in which case If a deviation from this is found, for example a zone temperature of the furnace device 110 is adjusted and preferably regulated in such a way that the austenite proportion of the product P predicted for the second location (II) or for the third location (III) is within a desired quality window for the target value of the austenite content.

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).
