Abstract
A method for producing a metal strip, in which the strip is rolled in a multi-stand rolling mill, is removed behind the final rolling stand of the rolling mill in the direction of conveyance, and is cooled in a cooling device. The strip or metal sheet is subjected to additional rapid cooling immediately after passing the working rollers of the final rolling stand, wherein the strip or the metal sheet is cooled at least partially within the extent of the final rolling stand in the direction of conveyance, wherein rapid cooling is performed by applying a coolant to the strip or metal sheet from above and from below, wherein the volume flow of coolant that is applied to the strip or metal sheet from below measures at least 120% of the volume flow of coolant that is applied to the strip or metal sheet from above.
