Abstract: The invention essentially is characterized in that downstream of the casting machine and upstream of the rolling device, in particular immediately behind shears for cutting the thin slab or the pre-strip, there is provided a scrap removal device, in particular a coiling device that winds the thin slabs or pre-strip into a coil which is removed from the installation as scrap. Therefore, the quality of the coil winding is not important as the wound then slab or pre-strip need not anymore be advanced to the rolling train. The resulting coil can be lifted with a forklift and bind during the emergency maintenance of the rolling train, without use of any personnel. No additional crane is required for scrap removal. In addition, no constructional measures, e.g., construction of a gravel pit for material cut by shears, are necessary.

Abstract: A rolling mill for rolling metal products, comprising two roller stands with a stand cross-member. A roller is rotatably mounted in the roller stands. The roller is operatively connected to a balancing cross-member, and at least one hydraulic piston-cylinder system is arranged in the stand cross-member, with which a tensile force can be generated between the stand cross-member and the balancing cross-member by the hydraulic piston-cylinder system. In order to prevent leakages in particular in the event of tall mill ascending paths, the piston-cylinder system has a cylinder housing with an upper axial end and a lower axial end. A piston is movably arranged in the cylinder housing, and the piston protrudes beyond the cylinder housing both at the upper axial end as well as at the lower axial end in each operating state.
