Embodiment Construction

[0033] exist figure 1 with figure 2 A cast-rolling plant can be seen in the figure, in which the metal strip 1 is produced. For this purpose, the thin slab 3 is first cast in a casting machine 2 known per se and then fed to a rolling mill 4, 5, which here includes a roughing mill 4 (consisting of one or several stands) and a finishing mill5. The casting machine 2 has a continuous casting strand cooling device, which is provided with narrow cooling zone divisions (Kühlzonenteilung) for temperature zone regulation in a wide range, in order to be able to adjust the temperature from the continuous casting machine. Uniform outlet temperature.

[0034] The cast-rolling plant also has various other elements that are known per se from such plants. Arranged downstream of the casting machine 2 in the strip transport direction F is a water jet descaling device 12 for cleaning the slabs. The roughing mill 4 is followed by a strip shear 11 . The shearing machine is used to cut off t...

Abstract

The invention relates to a method for the production of a metal strip (1) by roll casting, wherein initially a thin slab (3) is cast in a casting machine (2), wherein said slab is subsequently rolled in at least one rolling train (4, 5) while utilizing the primary heat of the casting process, wherein in a first operating mode a continuous production of the metal strip (1) may occur by directly coupling the casting machine (2) to the at least one rolling train (4, 5) (continuous rolling), and wherein in a second operating mode a discontinuous production of the metal strip (1) may occur by decoupling the casting machine (2) from the at least one rolling train (4, 5) (batch operation). In order to increase the flexibility of the system, the invention provides according to the method that slabs (3) or pre-strips (3') cast in the belt conveying direction (F) behind the casting machine (2) are removed from the main transport line (6) during the operation of the discontinuous production of the metal strip (1), stored, and later re-transported into the main transport line (6), wherein the slabs (3) or pre-strips (3') removed are brought to a desired temperature or are maintained at a desired temperature before the same are re-transported into the main transport line (6). The invention further relates to a device for the production of a metal strip (1) by roll casting.

Description

technical field [0001] The invention relates to a method for producing metal strip by casting and rolling, in which first a thin slab is cast in a casting machine, wherein the thin slab is then processed in at least one rolling mill using the initial heat of the casting process rolling, wherein in a first mode of operation a metal strip can be produced continuously by direct coupling between the casting machine and the at least one rolling mill (endless rolling) and wherein in a second mode of operation The metal strip can be produced discontinuously (batch operation) by decoupling the casting machine from the at least one rolling mill. Furthermore, the invention relates to a device for producing metal strip by casting and rolling. Background technique [0002] Plants of this type are known under the name CSP plants as thin slab-thin metal strip cast-rolling plants. Endless rolling from casting heat has been known for a long time, but this has not yet been accepted by the ...
