  • the surface treatment treatment tools are thermally less heavily loaded than in the methods known from the prior art.
  • There are even temperature-sensitive or not specially designed for high temperatures processing method used because due to the previous partial temperature reduction, the life of the tools, such as abrasive belts or grinding wheels, and thus their life is increased. Disadvantageous decomposition of the abrasive belt with smearing of the residues on the metal surfaces or bursting of grinding wheels does not occur.
  • the targeted temperature reduction is limited to the surface of the metallic product and advantageously tuned so that the machining resistance of the workpiece is not affected in an undesirable manner.
  • both all surfaces of the metallic product for example a thin slab section, i. Bottom and top as well as the side surfaces to be cooled.
  • only one surface for example, only the top of the metallic product is cooled, or only defined portions of surfaces.
  • the method is not limited to the application of slabs or thin slabs for the production of sheets and strips.
  • the surface treatment complex with the step sequence surface inspection, partial cooling of the surfaces and surface treatment immediately precedes a cleaning process, preferably a descaling process.
  • the grinding can be used using known tools such as abrasive belts, discs or stones with different Komart and grain.
  • the surface treatment on the partially cooled surfaces takes place together with the preferably proposed preparatory process steps in a continuously cast steel product preferably between the casting and - preferably directly following - rolling process instead.
  • Surface treatment is either integrated inline into this production line (X) or taken offline in a sideline (Y).
  • the plant for the production of steel sheets and strips consists essentially of a continuous casting plant 1 (schematically indicated here by a mold) for a strand 2 of 30 to 250 mm thickness, preferably 30 to 130 - this thickness specification does not limit the scope of the invention - a cross-cutting device 3, a device 4 for heating or balancing the temperature, for example a Hubbalkenofen or a roller hearth furnace, and a rolling mill 5 (here schematically with two rolling stands 5a, 5b indicated ).
  • the details of the rolling train (Vorgerüste, Coilbox, etc.) and adjoining the rolling mill 5 cooling devices and coiler are not shown.
  • the separator can be dispensed with the separator.
  • the cast slab strand 2 is divided after the deflection in the horizontal by the cross-cutting device 3, preferably in the form of a dividing shear, into sections and conveyed through the oven 4.
  • the heated in the oven 4 to homogenous rolling temperature or thermally balanced slab sections are then rolled in the embodiment shown in the rolling train 5 to tapes. This process is referred to below as production line (X).

  • a device for partial cooling 7 is arranged before the device for surface treatment 6 - seen in the conveying direction -.
  • both the lower and upper side of the respective slab section are simultaneously cooled in a defined section by means of a two-part cooling device (parts 7a, 7b), for example by means of nozzles, which apply a cooling medium to the surface.
  • the core temperature of the slabs by the partial cooling substantially unaffected. It is only a slow steady temperature drop due to the overall thermal conditions, i. the cooling after the casting process, determine.
  • the surface temperature of the slabs drops to temperatures below 900 ° C, preferably to a temperature range between 500 to 900 ° C, which has an advantageous effect on the service life of the tools used for machining surface treatment.
  • a homogenization of the temperatures or structural regions over the slab cross-section in the furnace 4 is ensured.
  • austenitic and acid-resistant austenites which do not convert on cooling, partial cooling of the surface or parts of the surface, even at low temperatures, is unproblematic.
  • corresponding components are provided with the same reference numerals.
  • the processing means 6 are preceded by a device for surface inspection 8 in addition to a surface cooling device 7.
  • This is also composed of two components 8a, 8b, in order to take in each case the top and bottom of the slabs 2 over a defined section continuously as they pass through and to detect any surface defects.
  • only a selective surface processing is performed automatically in the subsequent surface treatment device 6, for example by the Only apply abrasives locally to the slab surface.
