  • CSP plants or also under the name CEM (Compact Endless Cast & Rolling Mill) .
  • CSP plants or also under the name CEM (Compact Endless Cast & Rolling Mill) .
  • Such systems can be operated in endless operation, in which the rolled metal strip is produced continuously. During this continuous operation, the cast thin slab is then fed continuously to the roller hearth furnace and the rolling mill.
  • the problem with the continuous operation is that this creates a "rigid" connection between the continuous casting plant and the rolling mill, the temperature in the entire plant, in particular in the finishing mill in the endless process, not always being able to be kept at the necessary level, depending on the casting speed.
  • Such systems have therefore also been further developed in such a way that a batch operation is possible in which, by separating the cast thin slab, there is a decoupling between the casting plant / casting machine and the rolling mill, and thereby a discontinuous production of the metal strip is possible.
  • Such a production facility is from the DE 10 2008 020 412 A1 known.
  • roller hearth furnace and rolling mill which are arranged in series, this system also already has two slab or belt cutting devices and an oven conveyor system.
  • the thin slab casting line is first fed to a first rolling stand on the rolling mill, which is then followed by a first slab or strip cutting device.
  • the job of the furnace is to heat the slab after cutting and to even out the temperature of the slab.
  • the slab is then drawn into the rolling mill at a higher speed than the casting speed.
  • This is followed by a furnace conveyor system followed by a roller hearth furnace with a downstream second slab or belt separating device, which is arranged on the inlet side to a second stand group of the rolling mill.
  • the EP 2399683 shows a production system, which in series a thin slab caster upstream of a roller hearth furnace, the roller hearth furnace receiving the casting strand or at least a part length of the casting strand and a casting line which is heated or kept warm in the roller hearth furnace or the at least one part length separated therefrom and which is connected downstream of the roller hearth furnace assigned coiler system, wherein the continuous caster and the rolling mill can be operated in an endless operating mode, and wherein the outlet side of the roller hearth furnace is assigned an oven conveyor system arranged laterally to the roller hearth furnace and the rolling mill has a first stand group and a second stand group spaced apart therefrom, with one arranged between first and second stand group Heating device, in particular induction heating, and furthermore in the slab inlet direction on the inlet side in front of the roller hearth furnace a first slab or Belt separator arranged and in the slab outlet direction on the outlet side after the roller hearth
