A method and an arrangement for rolling hot wide strips from continuously cast thin slabs in successive steps of operation of a rolling line which includes a continuous finishing train. One or more casting lines and individual thin slabs are severed from the cast strand. The thin slabs are homogenized and adjusted to rolling temperature in an equalizing furnace and the thin slabs are transferred from the equalizing furnace to the rolling line. Roller-type turning furnaces provided in each of the casting lines and in the rolling line are use by turning the roller-type turning furnaces toward each other into positions which are inclined relative to the casting and rolling lines in the manner of switches for alternatingly conveying thin slabs from one of the casting lines through the roller-type turning furnaces into the rolling line.

Method and arrangement for rolling hot wide strips from continuously

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 returned in the reverse direction into the process chain.

Method and apparatus for manufacturing hot-rolled strips or sections

An invention is directed to a method and an installation for producing a hot-rolled steel strip from continuously cast primary material in consecutive work steps, wherein the primary material is brought to hot rolling temperature after solidification and is inserted into a rolling mill for rolling out into a finished strip, wherein the primary material is coiled after reaching the hot rolling temperature, is stored intermediately in a rotary hearth furnace, and is recalled, as needed, uncoiled and rolled out to form a finished strip, the intermediate storage being effected immediately prior to entering the finishing train, the coils being preferably stored intermediately in a horizontal position and with a horizontal coiling axis, a subsequent heating being effectable during the intermediate storage.

Rolled stock running out of a rolling mill is parted into lengths suitable for the cooling bed. Rolled stock cross sections of various sizes are retarded both at approach speeds of more than approximately 20 m/sec and slower, alongside the cooling bed in an approach roller feed bed and then transversely conveyed over the cooling bed. In order to avoid requiring an uneconomically long cooling bed as a result of the sequence times of the lengths of rolled stock, three or more longitudinal braking sections are arranged side by side to enable thin lengths at a high approach speed to be retarded in rapid succession and conveyed across to the cooling bed. Covering means of the braking sections are constructed to provide additional retardation of the lengths, e.g. by blowing air, by lowering brake shoes or by the action of linear electromagnetic motors.
