摘要： A processing plant for metal strips (1) has a welding machine, a strip store downstream of the welding machine and a processing device downstream of the strip store. The metal strips are welded to form a continuous strip with the welding machine, which is stored in the strip store and output from there to the processing device. The metal strips are connected via diagonally extending weld seams. To join the weld seams, first the strip head (2) and the strip foot (3) of the metal strips are twisted and the two strips are connected by forming the weld seam. The weld seam extends only transversely to the transport direction (x) during the welding process. Finally, the strip head and the strip foot of the metal strips are twisted back again. As a result, the weld seam now extends diagonally to the transport direction (x).

摘要： A rolling mill has a rolling stand (1) in which a flat rolled product (2) composed of metal is rolled. A sensor device (6), which detects at least one measured variable (M) characteristic of a material property of the flat rolled product (2), is arranged upstream and/or downstream of the rolling stand (1). The material property can be, in particular, an electromagnetic property or a mechanical property of the rolled product (2). The sensor device (6) transfers the detected measured variable (M) to a control device (9) for the rolling mill. Taking into account the measured variable (M), the control device (9) determines a control value (A) for the rolling stand (1). The control of the rolling stand (1) influences the material property of the flat rolled product (2). The control value (A) is a ratio of the peripheral speeds (vO, vU) at which the upper and the lower working rolls (3, 4) of the rolling stand (1) rotate.
