Abstract (en)
[origin: WO2014177664A1] The invention relates to a method for producing a metal strip (1), in which the strip (1) is rolled in a multi-stand rolling mill, is removed behind the final rolling stand (2) of the rolling mill in the direction of conveyance (F), and is cooled in a cooling device (3). In order to achieve a favourable grain structure and a high degree of surface evenness, the strip or metal sheet (1) is subjected to additional rapid cooling (4) immediately after passing the working rollers of the final rolling stand (2), wherein the strip or the metal sheet (1) is cooled at least partially within the extent of the final rolling stand (2) in the direction of conveyance (F), wherein rapid cooling is performed by applying a coolant to the strip or metal sheet (1) from above and from below, wherein the volume flow of coolant that is applied to the strip or metal sheet (1) from below measures at least 120 % of the volume flow of coolant that is applied to the strip or metal sheet (1) from above.
