Method of producing a metallic strip in a casting and rolling plant, wherein the casting and rolling plant comprises: - a casting machine for casting a slab, - a first furnace and/or a first roller path insulating section following the casting machine in the conveying direction of the metallic strip, - first shears arranged between the casting machine and the first furnace and/or the first roller path insulating section, - a roughing train with a plurality of roll stands (R1, R2), - a second furnace and/or a second roller path insulating section following the roughing train in the conveying direction of the metallic strip, - second shears arranged between the roughing train and the second furnace and/or the second roller path insulating section, - a finishing train with a plurality of roll stands (F1, F2, F3, F4, F5, F6), - a cooling path, - at least two coilers or a reversing coiler and - third shears arranged between the cooling path and the coiler installation, wherein one of the following operating modes is selected for production of the strip: a) endless rolling in which the casting machine, the roughing train and the finishing train are operatively connected with one another and rolling of the material is carried out with casting machine mass flow, wherein the finished strips are separated at the coiler installation by means of the third shears; b) endless rolling in the roughing train, in which the casting machine and the roughing train are operatively connected with one another and rolling of the material is carried out with casting machine mass flow, as well as individual strip rolling (batch operation) in the finishing train, wherein the pre-strips rolled in the roughing train are separated by means of the second shears for individual strip rolling in the finishing train; c) individual strip rolling (batch operation) in the roughing train and individual strip rolling (batch operation) in the finishing train, wherein the slabs produced in the casting machine are separated by means of the first shears for individual strip rolling in the roughing train and in the finishing train; d) semi-endless rolling in the roughing train and/or semi-endless rolling in the finishing train, wherein the slabs produced in the casting machine are separated by means of the first shears for semi-endless rolling in the roughing train and/or wherein the pre-strips rolled in the roughing train are separated by means of the second shears for semi-endless rolling in the finishing train, wherein the finished strips are separated at the coiler installation by means of the third shears, characterised in that rolling in the finishing train is carried out with a plurality of roll stands, which takes place in accordance with the equation: 2.316 × h B × v B × e − 0.167 × n ≥ 480 m / min mm wherein n: number of stands in the finishing train h B: thickness of the slab in mm v B: slab speed in m/min. - a casting machine for casting a slab, - a first furnace and/or a first roller path insulating section following the casting machine in the conveying direction of the metallic strip, - first shears arranged between the casting machine and the first furnace and/or the first roller path insulating section, - a roughing train with a plurality of roll stands (R1, R2), - a second furnace and/or a second roller path insulating section following the roughing train in the conveying direction of the metallic strip, - second shears arranged between the roughing train and the second furnace and/or the second roller path insulating section, - a finishing train with a plurality of roll stands (F1, F2, F3, F4, F5, F6), - a cooling path, - at least two coilers or a reversing coiler and - third shears arranged between the cooling path and the coiler installation, a) endless rolling in which the casting machine, the roughing train and the finishing train are operatively connected with one another and rolling of the material is carried out with casting machine mass flow, wherein the finished strips are separated at the coiler installation by means of the third shears;
