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

A butt joint deep penetration laser welding method is used for joining facing end sections of flat steel products, each having a carbon content CS<0.02%. In order to improve such a method such that an improved weld quality in terms of geometry and strength is achievable with it, at least one carbon-containing carrier material is inserted into a butt joint gap between the end sections, the carbon content of which is C≥20·C, preferably C≥100·C, and/or carbon is inserted into the butt joint gap or applied to at least one end section, such that the volume of the carbon inserted into the butt joint gap corresponds to 1% to 20% of the volume of a melt produced by a butt joint deep penetration laser welding process.

A method for rinsing an overflow chamber at the bath-side end of a snout of a device for hot-dip coating a metal strip is presented. The snout guides the metal strip in a protective gas atmosphere before the metal strip is coated with a metal melt. A rinsing cycle is carried out in the overflow chamber of the snout by feeding metal melt from the molten bath into the overflow chamber and at the same time, sucking and pumping said melt out of the overflow chamber back into the molten bath. This rinsing cycle can be performed even when the snout has been retracted from the melt by supplying the melt from the molten bath to the overflow chamber with a delivery pump.

A method and a vacuum-coating system () for coating a strip-shaped material (), in particular made of metal, are disclosed. Thereby, the strip-shaped material () is moved over a conveying section () in a transport direction (T) and vacuum-coated within a coating chamber () in which a vacuum is applied. When viewed in the transport direction (T) of the strip-shaped material (), at least one trimming shear () is arranged upstream of the coating chamber (), with which the strip-shaped material () 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 () over its longitudinal extension.

The invention relates to a method for coating a metal strip with the aid of a coating device. Within the coating device, the strip first runs through a coating container with a liquid coating agent and then a stripping nozzle device for stripping off excess coating agent from the surface of the strip. After the stripping nozzle device, the strip typically runs through a strip stabilizing device with a plurality of magnets on both broad sides of the strip. A form control deviation is determined as the difference between a determined actual form of the strip and a specified desired form of the strip and this form control deviation is used for activating the magnets of the strip stabilizing device in order to transform the actual form of the strip into the desired form. As an alternative possibility for producing a moment, in particular a bending moment, in the strip, on the basis of the form control deviation the magnets of the strip stabilizing deviceare moved in the widthwise direction R of the stripinto a traversing position in relation to the magnets on the respectively opposite broad side of the strip.

A device for coating a metal strip substrate includes a guiding apparatus for guiding the strip substrate along a movement path. A first coating apparatus coats a first main side of the strip substrate with an electrostatically charged coating powder which is in a fluidized state. The first coating apparatus is arranged under a first path section of the movement path. A second coating apparatus coats a second main side of the strip substrate with an electrostatically charged coating powder which is in a fluidized state. A redirecting unit redirects the strip substrate between the first and the second coating apparatus in such a way that the strip substrate in a second path section travels oppositely to the strip substrate in the first path section. The second coating apparatus is arranged at least partly geodetically under the second path section.

A method for operating an annealing furnace to anneal a metal strip provides that, initially, at least one target material property (MP) 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 (T) and/or a target speed (V) 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 MP.

A method for operating a coating device for coating a metal strip. The corresponding coating device has an electromagnetic strip-stabilizing device having a plurality of electromagnetic actuators or coils for applying forces to the metal strip. In order to ensure that the strip-stabilizing device is operated only within the operating limits thereof, the magnitudes of the set currents for the actuators or the coils are compared with a specified current threshold value or the forces applied to the metal strip by the actuators are compared with a specified force threshold value and the correction roller is moved into such an adjustment position that the magnitudes of the set currents are below the current threshold value or the magnitudes of the forces are below the force threshold value.

A rolling system has a rolling mill a rod workpiece, a wire block comprised of at least two roll stands downstream of the rolling mill, and a calibrating block comprised of three roll stands spaced apart in the direction downstream of the wire block. The workpiece is passed in the direction downstream in the direction from the rolling mill through the wire block and thereafter through the calibrating block with thickness reduction in each block. The gaps of the stands of the calibrating block are set at a fixed spacing and not varied during a rolling operation. A sensor measures the thickness of the workpiece upstream of the calibrating block, and gaps of the roll stands of the rolling mill or wire block are adjusted in accordance with the measured thickness such that the workpiece has a predetermined thickness on entering the calibrating block.

A rolling-mill cooling unit has a cooling-unit conveyor transporting fanned-out loops of wire in a transport direction toward a coiler spaced downstream from the cooling-unit conveyor and serving to organize the fanned-out loops of wire into coils or bundles. A feeder conveyor extending in the direction has an upstream end juxtaposed with the cooling unit and a downstream end juxtaposed with the coiler and is operable to advance the loops of wire from the unit to the coiler. The entire feeder conveyor can be shifted relative to the coiler and to the cooling unit in the direction so as to displace the upstream and downstream ends relative to the cooling unit and coiler.
