The invention relates to a device for changing the temperature of a metal strip including means for changing the temperature of the metal strip by heating or cooling. By using means for conveying the metal strip, the metal strip is moved in the strip direction relative to the means for changing the temperature of the metal strip. The object of providing a device for changing the temperature of metal strips, which allows improved process control and improved flatness of the treated metal strip, is achieved according to the invention by a device in that means for changing the temperature of the metal strip include a plurality of individual temperature-control means which each heat or cool the metal strip only in some regions, and at least the position of a plurality of the temperature-control means can be individually changed translationally and/or rotationally relative to the metal strip.

Method and device for changing the temperature of metal strips in a flatness-adaptive manner

The invention relates to a method for forming an aluminium composite material which has a core alloy made from an aluminium alloy of type AA5xxx or AA6xxx and at least one outer aluminium alloy layer provided on one or both sides, wherein the aluminium composite material is formed and the outer aluminium alloy layer provided on one or both sides has a yield strength Rof 25 MPa to 60 MPa in the soft or solution-annealed state. The method enables the production of large-surface, heavily formed aluminium alloy sheet metal parts, in particular also in outer skin quality.
