  • connection hooks are arranged on the module.
  • the substantially vertical support surfaces are oriented parallel to the strand conveying direction.
  • a very expedient embodiment of the invention is that the first strand guide segment after a successful removal of the mold and after the release of fasteners from the substantially vertical support surfaces substantially vertically upwards by the mold accommodating mold cavity is designed expandable.
  • the free mold space occupied by the mold is dimensioned such that the expansion of the segment support frame with a mounted or connected to it Strand guide segment with, for example, a hall crane through this free Kokillenraum is possible.
  • the first strand guide segment after releasing fasteners together with the mold substantially vertically upwardly form.
  • cooperating support surfaces are provided, for example, on the mold and the first strand guide segment, which produce a supportive contact with the mold during an upward movement of the first strand guide segment and entrains the mold during the upward movement of the first strand guide segment.
  • the first strand guide segment is releasably secured to the first segment support frame and each further strand guide segment supported on the first segment support frame is fixedly connected to the first segment support frame. At least another strand guide segment is firmly connected to the segment support frame.
  • the first segment support frame forms an extension of the outer arch frame of the detachable strand guide segment subsequent
  • Strand guide segment The extension of the outer arch frame of the one strand guide segment extends in the direction of the mold and carries the substantially vertical support surfaces for the further strand guide segments arranged between the mold and the connected strand guide segment.
  • all strand guide segments supported on the first segment support frame are detachably fastened to this segment support frame.
  • at least the last strand guide segment in the strand conveying direction together with the segment frame can be installed or removed as a structural unit in the continuous casting plant. But it can also all mounted on the first segment frame Strand guide segments together with this as a unit in the continuous casting and on this expanded.
  • At least the first strand guide segment in it rotatably mounted strand guide rollers on the metal strhack both in the direction of its width extension and in the direction of its thickness extension adjustable are formed.
  • This employment preferably takes place with hydraulic adjusting devices. These act on the one strand side associated strand guide rollers, which are grouped together on a roll holder rotatably supported.
  • the strand guide rollers are assigned spray nozzles for coolant application to the surface of the metal strand, which are aligned in the direction of width extension and in the direction of the thickness extension of the metal strand to different thicknesses and widths with a Spritzdüsen- adjustment.
  • the last strand guide segment supported on the first segment support frame is provided with strand guide rollers which are adjustable against the metal strand at least in the direction of its thickness extension.
