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.
