Abstract

A method for producing a metallic strip by continuous casting-rolling, wherein a slab is cast in a casting machine and then sent to a finishing mill located downstream, relative to the transport direction of the strip. In the event that the transport of the slab or strip comes to a complete or substantially complete standstill, the following steps are carried out: (a) cutting through the strip at a first point; (b) cutting through the strip at a second point that is 0.1-5.0 m upstream from the first point; (c) removing the cut-out piece of strip to create a gap in the strip; (d) conveying new strip material into the area of the gap from the area located upstream of the first point; and (e) cutting off pieces of the new strip material conveyed from upstream according to step (d) and removing the pieces from the transport line.
