Abstract: In the case of a production plant which comprises in series a thin-slab continuous casting plant (1), which is arranged upstream of a roller hearth furnace (2), the roller hearth furnace (2) and a rolling mill (3), which is arranged downstream of the roller hearth furnace (2) and has an assigned reeling plant (21), wherein the continuous casting plant (1) and the rolling mill (3) can be operated in a continuous operating mode, the intention is to provide a solution that allows a slab buffer capacity to be provided for a continuously operated thin slab continuous casting plant when there is a fault causing a standstill in the transport of the slab or strip. This is achieved by the production plant having four slab or strip cutting devices (10, 14, 17, 24), which are arranged upstream and downstream of the roller hearth furnace (2), in a section along the length of the roller hearth furnace (2) and on the outlet side of a first separate roll line (12) of the rolling mill (3).

Abstract: A method for producing a metal strip in a cast-rolling installation, the cast-rolling installation includes the following: a casting machine, a first furnace, a first shear, a roughing train, a second furnace, a second shear, a finishing train, a cooling section, a reeling system, and a third shear. In order to allow a flexible reaction to different operating conditions, at least one of the following operating modes is selected in order to produce the strip: a) a continuous rolling, in which the casting machine, the roughing train, and the finishing train are operatively connected together; b) a continuous rolling in the roughing train and a single-strip rolling in the finishing train; c) a single-strip rolling in the roughing train and a single-strip rolling in the finishing train; and d) a semi-continuous rolling in the roughing train and/or a semi-continuous rolling in the finishing train.

Abstract: A method for producing a metal strip (1) by casting and rolling, wherein first a slab (3) is cast in a caster (2) by dispensing metal from a mold (4), wherein the slab (3) is deflected from the vertical direction to the horizontal direction in the region of a strand guide (5), wherein the slab (3) is then tempered in a furnace (6), wherein the slab (3) is rolled in a rolling train (7) after the furnace (6) and wherein the slab (3) is processed either in discontinuous batch operation or in continuous or semi-continuous operation in dependence on a specified manner of operation. According to the invention, in order to create optimal process conditions for all desired operating modes, the slab (3) to be rolled or the metal strip (1) being rolled is subjected to heating in the region of the rolling train (7) at least between two roll stands (8, 9, 10, 11, 12, 13, 14) by means of an inductor (15).
