Abstract
The invention relates to a method for controlling a metal strip to be heat-treated, contained in a continuously operated heat treatment furnace and proceeding in an essentially horizontal direction and suspended position in a zone arranged between elements meant for supporting the metal strip when said metal strip is being cooled. The trajectory of the metal strip is measured by a measuring device, and on the basis of the obtained measurement results, the metal strip is subjected to a controlled cooling agent jet, so that the trajectory of the metal strip, at least in the zone located between the elements meant for supporting the metal strip, is made to proceed in between devices installed around the trajectory and meant for conveying the cooling agent.
