Abstract
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.
