A method for drying a strip () or sheet metal that runs through a rolling mill is characterized in that the strip () or the sheet metal is cooled to a lower temperature in a cooling section by means of a coolant, in particular a cooling liquid, down-stream of a hot strip mill () or, in case of sheet metal, after passing through at least one roll stand (), and in that the coolant, in particular the cooling liquid, and subsequently the moisture remaining on the strip () or the sheet metal is removed from the strip () or sheet metal by means of a drying apparatus ().

The invention relates to a method for producing strips () of steel, preferably of silicon steel, in particular of grain-oriented silicon steel or of multiphase steel in which a slab () is initially cast in a casting machine (), wherein this is then rolled in at least one roll train () to form strip () and wherein before and/or after the at least one roll train (), the slab is heated in at least one furnace (). In order to improve the quality and the scope for producing grain-oriented silicon steel or multiphase steel, the invention provides that the slab () is heated to a pre-rolling temperature (T) after the casting machine () and before a pre-roll train () in a first furnace (), or the slab () enters into the pre-roll train () using the casting heat without the presence of the first furnace (), the slab () is then rolled in the pre-roll train (), the slab is then heated after the pre-roll train () in a second furnace () to a defined temperature (T) that is higher than the pre-rolling temperature (T), and then the slab () is rolled to the final strip thickness in a finish roll train ().
