Abstract
A rolling mill with a cooling zone for cooling and scissors for cross-cutting metal strips, which are preferably made of steel. A method and a device enables metal strips with thicknesses >4 mm and/or metal strips made of high-strength materials to be cross-cut by the scissors arranged after a production line and a cooling zone. In the method, the metal strip (6) is cooled in the cooling zone (10) to a specified temperature profile in the longitudinal direction of the metal strip (6) such that the metal strip (6) has a higher temperature in the region of the strip head of the trailing metal strip portion (31) and the strip base of the leading metal strip portion (32) than in the upstream and downstream regions.
