Abstract
The invention relates to a method and an installation for hot-rolling strips using a reversible Steckel rolling frame (8), each side of which is equipped with a respective furnace coiler (9, 10) and a driving mechanism (17,18), provided between the furnace coiler (9, 10) and Steckel rolling frame (8). The aim of the invention is to crop particularly thin, hot strips. To achieve this, the strip is cropped during the reversible rolling process by a single pair of flying cropping shears (20), positioned between one of the driving mechanisms (17) and the Steckel rolling frame (8). The cropping shears comprise in particular a drum blade.

Installation for hot rolling strip with a reversing Steckel rolling stand (8), on either side of which a furnace reel (9, 10) is arranged, with drivers (17, 18), which are installed between each furnace reel (9, 10) and the Steckel rolling stand (8), and with a cropping shear, wherein a single flying cropping shear (20) is installed between one driver (17) and the Steckel rolling stand (8), wherein the cropping shear (20) is a drum blade cropping shear with both an upper and lower adjustable blade drum (28a, b) for making the flying cut of the strip material, such that each blade drum (28a, b) can be adjusted between a position some distance from the strip material during the rolling operation and a cutting position, wherein a heat shield (41a, b) can be swung into the space between the strip material and the corresponding adjustable blade drum (28a, b), which has been moved into its position some distance from the strip material.
Installation for hot rolling strip with a reversing Steckel rolling stand (8), on either side of which a furnace reel (9, 10) is arranged, with drivers (17, 18), which are installed between each furnace reel (9, 10) and the Steckel rolling stand (8), and with a cropping shear, wherein a single flying cropping shear (20) is installed between one driver (17) and the Steckel rolling stand (8), wherein a roller table area, which is located immediately adjacent to the cropping shear (20) and serves to convey the strip material through the shear, is formed by two independently swiveling roller table units (42, 43), wherein, to allow removal of the crop end, each roller table unit (42, 43) can be swiveled out of the horizontal position in such a way that the crop end can fall freely, without hindrance by the roller table unit (42, 43), and that the roller table unit (42, 43) can then be swung further in the same swiveling direction, until it again reaches its horizontal position.
