Abstract

Hot-rolled strips or sections from continuously cast primary material are manufactured in successive work steps in a closed process and arrangement chain. The endless continuously cast primary material is divided after solidification into individual slab pieces of predetermined length. The slab pieces are heated in an equalizing furnace to rolling temperature and are then rolled into the predetermined final dimensions. For bridging a comparatively short interruption, for example, a ten-minute interruption of the rolling process, a slab piece obtained from the uninterrupted casting process is moved into a buffer zone of the equalizing furnace. For bridging relatively long interruptions of the rolling process, primary material obtained during the uninterrupted casting process is divided into slab pieces having a predetermined length, the slab pieces are moved out of the process chain by a furnace part constructed as a transverse conveyor and the slab pieces are conveyed into a side line laterally and parallel offset next to the production line. The slab pieces are stored as necessary and stacked in a holding furnace and, after the interruption has been eliminated, the slab pieces are…
